+npm install
+cd ..
+
+# Copy environment file
+cp server/.env.example server/.env
+```
+
+### 3. Configure (Optional)
+
+Edit `server/.env` to customize:
+
+```env
+# Server port
+PORT=3001
+
+# ACE-Step API URL (default: http://localhost:8001)
+ACESTEP_API_URL=http://localhost:8001
+
+# Database location
+DATABASE_PATH=./data/acestep.db
+
+# Optional: Pexels API key for video backgrounds
+# Get a free key at https://www.pexels.com/api/
+PEXELS_API_KEY=your_key_here
+```
+
+## Usage
+
+### Step 1: Start ACE-Step API Server
+
+In a terminal, start the ACE-Step API server:
+
+```bash
+cd /path/to/ACE-Step
+uv run acestep-api --port 8001
+```
+
+Wait until you see "Application startup complete" before proceeding.
+
+### Step 2: Start ACE-Step UI
+
+In another terminal:
+
+```bash
+cd ace-step-ui
+./start.sh
+```
+
+Or manually in two terminals:
+
+```bash
+# Terminal 1 - Backend
+cd server && npm run dev
+
+# Terminal 2 - Frontend
+npm run dev
+```
+
+### Step 3: Open the UI
+
+Open http://localhost:3000 in your browser.
+
+On first launch, you'll be asked to set a username. This is stored locally.
+
+## Generating Music
+
+1. **Simple Mode**: Enter a description of the music you want
+2. **Custom Mode**: Fine-tune parameters like BPM, key, duration, and add lyrics
+3. Click "Create" to generate
+
+Generated songs are saved locally and appear in your library.
+
+## Additional Features
+
+### Audio Editor
+Click the waveform icon on any song to open the built-in audio editor for trimming, fading, and effects.
+
+### Stem Extraction
+Extract vocals, drums, bass, and other stems from any song using the Demucs-powered stem separator.
+
+### Video Generator
+Create music videos with:
+- Custom backgrounds from Pexels (requires API key)
+- Gradient animations
+- Lyrics display
+- Album art overlay
+
+## Troubleshooting
+
+### "ACE-Step API not reachable"
+Make sure the ACE-Step API server is running on port 8001:
+```bash
+cd /path/to/ACE-Step
+uv run acestep-api --port 8001
+```
+
+### "CUDA out of memory"
+- Close other GPU-intensive applications
+- Try generating shorter clips (30-60 seconds)
+- Reduce batch size if available
+
+### Songs show 0:00 duration
+This can happen if FFprobe is not installed. Install it:
+```bash
+# Ubuntu/Debian
+sudo apt install ffmpeg
+
+# macOS
+brew install ffmpeg
+```
+New songs will automatically detect duration. For existing songs, they'll update when played.
+
+## Development
+
+```bash
+# Run in development mode with hot reload
+./start.sh
+
+# Build for production
+npm run build
+cd server && npm run build
+```

+<h3>The story behind AudioMass. And a short rant on web interfaces.</h3>
+
+<p>I wrote AudioMass back in June 2018 and it stayed dormant on my hard disk until I decided to share it with the world today (July 13th, 19 -- but you might be seeing this in 2020. Hi!!).
+It started as a personal small tool for quick visualization of waveforms. Later I added the ability to cut/copy/paste as well as fade in and out. And soon after good 'ol feature creep and perfectionism took over! Soon after, it turned to a challenge to see how close to a full-featured waveform editor it can get, whilst maintaining acceptable performance and small filesize.</p>
+
+<p>In general I am a big fan of the interfaces of DAWs <i>(Digital Audio Workstations)</i>, they are extremely, complex, intricate, versatile, and they manage to remain visually pleasant even through their infinite options and knobs. Many times I feel the web has taken a very wrong turn, as amazing interfaces such as...
+
+<p class="nomarg">Sonar</p>
+<img class="mid" src="/about/sonar.jpg" />
+
+<br />
+<p class="nomarg">Fruity loops</p>
+<img class="mid" src="/about/fruity.png" />
+
+<br />
+
+<p>Existed for more than 10-15 years now, while we are struggling with animating some rectangles for 60fps... So for AudioMass I wanted to try and make a fast and performant interface. Drawing inspiration from the examples I mentioned earlier rather than the tradiional web development practices. This is my unconvincing but truthfull excuse as to why the code is ugly; it is focused on being fast and getting the job done, with little regard on structure.</p>
+
+</div>
+
+<hr />
+
+<div>
+
+<h3>Building the interface</h3>
+
+<p>Let's say we have a <i>"PLAY"</i> button and when we press it the track begins to play. I suppose we would want the button's color and state to reflect that the track is now playing. So naively we would do something like;</p>
+
+
+<pre><code>btn.onclick = function () {
+	this.classList.add ('active');
+};</code></pre>
+
+<p>But what happens if we have a hotkey that triggers the same action? Let's say we press <i>[SPACEBAR]</i> and the track begins to play. Do we modify that button's class in the spacebar's handler?</p>
+
+<pre><code>document.onkeypress = function ( e ) { 
+  if ( e.keyCode === 32) {
+       e.preventDefault ();
+
+       document.querySelector ('.playbtn').classList.add ('active');
+  }
+};</code></pre>
+
+<p>And what happens, if there are 2 buttons, or one gets dynamically removed? Do we do selectAll and iterate? Hmmm...<br />
+And if the track is playing and we hit <i>[SPACEBAR]</i> or the play button again, we need to stop playing. What do we do then? You can see how this becomes messy very quickly as everything gets very tighlty coupled together in a big dependency ball.</p>
+
+
+
+<p>Introducing the observer pattern. Actions are represented by events. So the above logic and be expressed as;</p>
+
+
+<pre><code>btn.onclick = function () {
+	FireEvent ('RequestTogglePlay');
+};
+
+On ('WillPlay', function () {
+	btn.classList.add ('active');
+});
+
+On ('WillStop', function () {
+	btn.classList.remove ('active');
+});
+
+
+
+document.onkeypress = function ( e ) {
+  if ( e.keyCode === 32) {
+       e.preventDefault ();
+
+       FireEvent ('RequestTogglePlay');
+  }
+};
+
+
+
+On ('RequestTogglePlay', function () {
+	if (track.is_playing) {
+		FireEvent ('WillStop');
+		track.stop ();
+	}
+	else {
+		FireEvent ('WillPlay');
+		track.play ();
+	}
+});
+
+track.onPlayStart = function () {
+	FireEvent ('DidPlay');
+};
+track.onPlayStop = function () {
+	FireEvent ('DidStop');
+};
+</code></pre>
+
+<p>Now this is completely decoupled and dependency free! The button will set its state according to the events it receives, and both the button and the spacebar key rely on the same mechanisms.
+You may notice the vocabulary we are using. <i>"Request"</i>, <i>"Will"</i> and <i>"Did"</i>. These are arbitrarilly chosen to impose some extra structure.<br /> <i>"Request"</i> denotes intent to perform an action, it is not guaranteed that the action will execute as there might be conditions preventing it (eg unitialized or still loading objects). <i>"Will"</i> means that the conditions passed and we are attempting to perform the action. And <i>"Did"</i> means that the action just got performed.<br />
+It might be a bit too verbose, but it worked very well for structuring AudioMass's interface.</p>
+</div>
+
+<hr />
+
+<div>
+<h3>Dockable UI</h3>
+
+<p>One thing I love about DAW interfaces, is that every window can be pulled out of the main host. I fondly remember having 3 screens full of VST plugins. So can we do the same in the browser?</p>
+
+
+<video src="/about/dock_ui.mp4" autoplay muted playsinline controls loop></video>
+
+
+<p>Yes! And it is using some of the oldest tricks in the book. Essentially we create a pop-up window with <i>window.open</i> and just pass buffers to its <i>documentWindow</i> object. Surprisingly it is quite performant on all browsers except IE Edge. I believe they are serializing in ascii or base64 every packet or something. Also Chrome has an interesting bug where you can't pass more than 512 byte buffers.</p>
+
+<p>So for the undocked window, we call <i>window.open</i>. But how do we make it work when it is docked? It would be quite cumbersome to write the same functionality twice, once as a standalone page, and once as an in-page script. Luckily we can avoid that completely, and re-use the same page by using iframes.</p>
+
+<p>The only difference is that the undocked version uses <i>window.opener</i> to refference its parent, whereas the iframe uses <i>window.parent</i>.</p>
+
+</div>
+
+
+<hr />
+
+<div>
+<h3>Future work and performance considerations</h3>
+
+<p>The next big feature that is planned, is multitrack support. The ability to mix tracks and different sounds is currently lacking and its usefulness as it stands is limited.</p>
+
+<hr />
+
+<p>There is also a lot of room for improvement in almost all aspects.</p>
+
+<p>First of all we can further reduce the filesize by around 20kb by removing the library we are using for rendering the waveform. We use only a fraction of its functionality so there is no reason to include it all.</p>
+
+<p>We can also optimize a lot the rendering of the waveform. I heavily modified the library used to compute and draw only the visible range. However it is still clearing and re-drawing all of the canvas at each frame. We can take advantage of 2d Context's translate calls, and shift the canvas around instead of redrawing all of the pixels.</p>
+
+<p>We can also move some operations to a background thread, such as the filters processing so that the UI does not freeze when applying a long chain of effects.</p>
+
+<br />
+
+
+<p>However, the biggest issue I encountered, is the Web Audio API itself. Every operation results in iterating over multiple long arrays per frame. Eventually the garbage collector fires and crackling is introduced. Only way to go around this is to use a small fftSize, but then the frequency range we have to work with is very narrow. Perhaps a pure WASM implementation would outperform trying to modify audio signals with JS. Only one way to find out I guess :) </p>
+<p>Additionally, <i>decodeAudioData</i> provides no progress callback, and no way of cancelling it. So if you attempt to load a huge audio file, you will waste resources until it gets processed. There is no way around this currently and it can get annoying if you push a big file by mistake.</p>

+ * ResvFrameBegin:<BR>
+ * Called (repeatedly) at the beginning of a frame. Updates the maximum size of
+ * the reservoir, and checks to make sure main_data_begin was set properly by
+ * the formatter<BR>
+ * Background information:
+ * 
+ * This is the original text from the ISO standard. Because of sooo many bugs
+ * and irritations correcting comments are added in brackets []. A '^W' means
+ * you should remove the last word.
+ * 
+ * <PRE>
+ *  1. The following rule can be used to calculate the maximum
+ *     number of bits used for one granule [^W frame]:<BR>
+ *     At the highest possible bitrate of Layer III (320 kbps
+ *     per stereo signal [^W^W^W], 48 kHz) the frames must be of
+ *     [^W^W^W are designed to have] constant length, i.e.
+ *     one buffer [^W^W the frame] length is:<BR>
+ * 
+ *         320 kbps * 1152/48 kHz = 7680 bit = 960 byte
+ * 
+ *     This value is used as the maximum buffer per channel [^W^W] at
+ *     lower bitrates [than 320 kbps]. At 64 kbps mono or 128 kbps
+ *     stereo the main granule length is 64 kbps * 576/48 kHz = 768 bit
+ *     [per granule and channel] at 48 kHz sampling frequency.
+ *     This means that there is a maximum deviation (short time buffer
+ *     [= reservoir]) of 7680 - 2*2*768 = 4608 bits is allowed at 64 kbps.
+ *     The actual deviation is equal to the number of bytes [with the
+ *     meaning of octets] denoted by the main_data_end offset pointer.
+ *     The actual maximum deviation is (2^9-1)*8 bit = 4088 bits
+ *     [for MPEG-1 and (2^8-1)*8 bit for MPEG-2, both are hard limits].
+ *     ... The xchange of buffer bits between the left and right channel
+ *     is allowed without restrictions [exception: dual channel].
+ *     Because of the [constructed] constraint on the buffer size
+ *     main_data_end is always set to 0 in the case of bit_rate_index==14,
+ *     i.e. data rate 320 kbps per stereo signal [^W^W^W]. In this case
+ *     all data are allocated between adjacent header [^W sync] words
+ *     [, i.e. there is no buffering at all].

+ PSYCHO ACOUSTICS
+
+
+ This routine computes the psycho acoustics, delayed by one granule.
+
+ Input: buffer of PCM data (1024 samples).
+
+ This window should be centered over the 576 sample granule window.
+ The routine will compute the psycho acoustics for
+ this granule, but return the psycho acoustics computed
+ for the *previous* granule.  This is because the block
+ type of the previous granule can only be determined
+ after we have computed the psycho acoustics for the following
+ granule.
+
+ Output:  maskings and energies for each scalefactor band.
+ block type, PE, and some correlation measures.
+ The PE is used by CBR modes to determine if extra bits
+ from the bit reservoir should be used.  The correlation
+ measures are used to determine mid/side or regular stereo.
+ */
+/*
+ Notation:
+
+ barks:  a non-linear frequency scale.  Mapping from frequency to
+ barks is given by freq2bark()
+
+ scalefactor bands: The spectrum (frequencies) are broken into
+ SBMAX "scalefactor bands".  Thes bands
+ are determined by the MPEG ISO spec.  In
+ the noise shaping/quantization code, we allocate
+ bits among the partition bands to achieve the
+ best possible quality
+
+ partition bands:   The spectrum is also broken into about
+ 64 "partition bands".  Each partition
+ band is about .34 barks wide.  There are about 2-5
+ partition bands for each scalefactor band.
+
+ LAME computes all psycho acoustic information for each partition
+ band.  Then at the end of the computations, this information
+ is mapped to scalefactor bands.  The energy in each scalefactor
+ band is taken as the sum of the energy in all partition bands
+ which overlap the scalefactor band.  The maskings can be computed
+ in the same way (and thus represent the average masking in that band)
+ or by taking the minmum value multiplied by the number of
+ partition bands used (which represents a minimum masking in that band).
+ */
+/*
+ The general outline is as follows:
+
+ 1. compute the energy in each partition band
+ 2. compute the tonality in each partition band
+ 3. compute the strength of each partion band "masker"
+ 4. compute the masking (via the spreading function applied to each masker)
+ 5. Modifications for mid/side masking.
+
+ Each partition band is considiered a "masker".  The strength
+ of the i'th masker in band j is given by:
+
+ s3(bark(i)-bark(j))*strength(i)
+
+ The strength of the masker is a function of the energy and tonality.
+ The more tonal, the less masking.  LAME uses a simple linear formula
+ (controlled by NMT and TMN) which says the strength is given by the
+ energy divided by a linear function of the tonality.
+ */
+/*
+ s3() is the "spreading function".  It is given by a formula
+ determined via listening tests.
+
+ The total masking in the j'th partition band is the sum over
+ all maskings i.  It is thus given by the convolution of
+ the strength with s3(), the "spreading function."
+
+ masking(j) = sum_over_i  s3(i-j)*strength(i)  = s3 o strength
+
+ where "o" = convolution operator.  s3 is given by a formula determined
+ via listening tests.  It is normalized so that s3 o 1 = 1.
+
+ Note: instead of a simple convolution, LAME also has the
+ option of using "additive masking"
+
+ The most critical part is step 2, computing the tonality of each
+ partition band.  LAME has two tonality estimators.  The first
+ is based on the ISO spec, and measures how predictiable the
+ signal is over time.  The more predictable, the more tonal.
+ The second measure is based on looking at the spectrum of
+ a single granule.  The more peaky the spectrum, the more
+ tonal.  By most indications, the latter approach is better.
+
+ Finally, in step 5, the maskings for the mid and side
+ channel are possibly increased.  Under certain circumstances,
+ noise in the mid & side channels is assumed to also
+ be masked by strong maskers in the L or R channels.
+
+
+ Other data computed by the psy-model:
+
+ ms_ratio        side-channel / mid-channel masking ratio (for previous granule)
+ ms_ratio_next   side-channel / mid-channel masking ratio for this granule
+
+ percep_entropy[2]     L and R values (prev granule) of PE - A measure of how
+ much pre-echo is in the previous granule
+ percep_entropy_MS[2]  mid and side channel values (prev granule) of percep_entropy
+ energy[4]             L,R,M,S energy in each channel, prev granule
+ blocktype_d[2]        block type to use for previous granule

+     * 5. compute the actual compression ratio 6. set mode based on compression
+     * ratio
+     *
+     * The remaining code is much simpler - it just sets options based on the

+<h3>The story behind AudioMass. And a short rant on web interfaces.</h3>
+
+<p>I wrote AudioMass back in June 2018 and it stayed dormant on my hard disk until I decided to share it with the world today (July 13th, 19 -- but you might be seeing this in 2020. Hi!!).
+It started as a personal small tool for quick visualization of waveforms. Later I added the ability to cut/copy/paste as well as fade in and out. And soon after good 'ol feature creep and perfectionism took over! Soon after, it turned to a challenge to see how close to a full-featured waveform editor it can get, whilst maintaining acceptable performance and small filesize.</p>
+
+<p>In general I am a big fan of the interfaces of DAWs <i>(Digital Audio Workstations)</i>, they are extremely, complex, intricate, versatile, and they manage to remain visually pleasant even through their infinite options and knobs. Many times I feel the web has taken a very wrong turn, as amazing interfaces such as...
+
+<p class="nomarg">Sonar</p>
+<img class="mid" src="/about/sonar.jpg" />
+
+<br />
+<p class="nomarg">Fruity loops</p>
+<img class="mid" src="/about/fruity.png" />
+
+<br />
+
+<p>Existed for more than 10-15 years now, while we are struggling with animating some rectangles for 60fps... So for AudioMass I wanted to try and make a fast and performant interface. Drawing inspiration from the examples I mentioned earlier rather than the tradiional web development practices. This is my unconvincing but truthfull excuse as to why the code is ugly; it is focused on being fast and getting the job done, with little regard on structure.</p>
+
+</div>
+
+<hr />
+
+<div>
+
+<h3>Building the interface</h3>
+
+<p>Let's say we have a <i>"PLAY"</i> button and when we press it the track begins to play. I suppose we would want the button's color and state to reflect that the track is now playing. So naively we would do something like;</p>
+
+
+<pre><code>btn.onclick = function () {
+	this.classList.add ('active');
+};</code></pre>
+
+<p>But what happens if we have a hotkey that triggers the same action? Let's say we press <i>[SPACEBAR]</i> and the track begins to play. Do we modify that button's class in the spacebar's handler?</p>
+
+<pre><code>document.onkeypress = function ( e ) { 
+  if ( e.keyCode === 32) {
+       e.preventDefault ();
+
+       document.querySelector ('.playbtn').classList.add ('active');
+  }
+};</code></pre>
+
+<p>And what happens, if there are 2 buttons, or one gets dynamically removed? Do we do selectAll and iterate? Hmmm...<br />
+And if the track is playing and we hit <i>[SPACEBAR]</i> or the play button again, we need to stop playing. What do we do then? You can see how this becomes messy very quickly as everything gets very tighlty coupled together in a big dependency ball.</p>
+
+
+
+<p>Introducing the observer pattern. Actions are represented by events. So the above logic and be expressed as;</p>
+
+
+<pre><code>btn.onclick = function () {
+	FireEvent ('RequestTogglePlay');
+};
+
+On ('WillPlay', function () {
+	btn.classList.add ('active');
+});
+
+On ('WillStop', function () {
+	btn.classList.remove ('active');
+});
+
+
+
+document.onkeypress = function ( e ) {
+  if ( e.keyCode === 32) {
+       e.preventDefault ();
+
+       FireEvent ('RequestTogglePlay');
+  }
+};
+
+
+
+On ('RequestTogglePlay', function () {
+	if (track.is_playing) {
+		FireEvent ('WillStop');
+		track.stop ();
+	}
+	else {
+		FireEvent ('WillPlay');
+		track.play ();
+	}
+});
+
+track.onPlayStart = function () {
+	FireEvent ('DidPlay');
+};
+track.onPlayStop = function () {
+	FireEvent ('DidStop');
+};
+</code></pre>
+
+<p>Now this is completely decoupled and dependency free! The button will set its state according to the events it receives, and both the button and the spacebar key rely on the same mechanisms.
+You may notice the vocabulary we are using. <i>"Request"</i>, <i>"Will"</i> and <i>"Did"</i>. These are arbitrarilly chosen to impose some extra structure.<br /> <i>"Request"</i> denotes intent to perform an action, it is not guaranteed that the action will execute as there might be conditions preventing it (eg unitialized or still loading objects). <i>"Will"</i> means that the conditions passed and we are attempting to perform the action. And <i>"Did"</i> means that the action just got performed.<br />
+It might be a bit too verbose, but it worked very well for structuring AudioMass's interface.</p>
+</div>
+
+<hr />
+
+<div>
+<h3>Dockable UI</h3>
+
+<p>One thing I love about DAW interfaces, is that every window can be pulled out of the main host. I fondly remember having 3 screens full of VST plugins. So can we do the same in the browser?</p>
+
+
+<video src="/about/dock_ui.mp4" autoplay muted playsinline controls loop></video>
+
+
+<p>Yes! And it is using some of the oldest tricks in the book. Essentially we create a pop-up window with <i>window.open</i> and just pass buffers to its <i>documentWindow</i> object. Surprisingly it is quite performant on all browsers except IE Edge. I believe they are serializing in ascii or base64 every packet or something. Also Chrome has an interesting bug where you can't pass more than 512 byte buffers.</p>
+
+<p>So for the undocked window, we call <i>window.open</i>. But how do we make it work when it is docked? It would be quite cumbersome to write the same functionality twice, once as a standalone page, and once as an in-page script. Luckily we can avoid that completely, and re-use the same page by using iframes.</p>
+
+<p>The only difference is that the undocked version uses <i>window.opener</i> to refference its parent, whereas the iframe uses <i>window.parent</i>.</p>
+
+</div>
+
+
+<hr />
+
+<div>
+<h3>Future work and performance considerations</h3>
+
+<p>The next big feature that is planned, is multitrack support. The ability to mix tracks and different sounds is currently lacking and its usefulness as it stands is limited.</p>
+
+<hr />
+
+<p>There is also a lot of room for improvement in almost all aspects.</p>
+
+<p>First of all we can further reduce the filesize by around 20kb by removing the library we are using for rendering the waveform. We use only a fraction of its functionality so there is no reason to include it all.</p>
+
+<p>We can also optimize a lot the rendering of the waveform. I heavily modified the library used to compute and draw only the visible range. However it is still clearing and re-drawing all of the canvas at each frame. We can take advantage of 2d Context's translate calls, and shift the canvas around instead of redrawing all of the pixels.</p>
+
+<p>We can also move some operations to a background thread, such as the filters processing so that the UI does not freeze when applying a long chain of effects.</p>
+
+<br />
+
+
+<p>However, the biggest issue I encountered, is the Web Audio API itself. Every operation results in iterating over multiple long arrays per frame. Eventually the garbage collector fires and crackling is introduced. Only way to go around this is to use a small fftSize, but then the frequency range we have to work with is very narrow. Perhaps a pure WASM implementation would outperform trying to modify audio signals with JS. Only one way to find out I guess :) </p>
+<p>Additionally, <i>decodeAudioData</i> provides no progress callback, and no way of cancelling it. So if you attempt to load a huge audio file, you will waste resources until it gets processed. There is no way around this currently and it can get annoying if you push a big file by mistake.</p>

+ *    GetTitleGain()
+ *
+ *  will return the recommended dB level change for all samples analyzed

+ *
+ *  will return the recommended dB level change for all samples analyzed

+ *  I set up the AnalyzeSamples routine to minimize memory usage and interface

+ * ResvFrameBegin:<BR>
+ * Called (repeatedly) at the beginning of a frame. Updates the maximum size of
+ * the reservoir, and checks to make sure main_data_begin was set properly by
+ * the formatter<BR>
+ * Background information:
+ * 
+ * This is the original text from the ISO standard. Because of sooo many bugs
+ * and irritations correcting comments are added in brackets []. A '^W' means
+ * you should remove the last word.
+ * 
+ * <PRE>
+ *  1. The following rule can be used to calculate the maximum
+ *     number of bits used for one granule [^W frame]:<BR>
+ *     At the highest possible bitrate of Layer III (320 kbps
+ *     per stereo signal [^W^W^W], 48 kHz) the frames must be of
+ *     [^W^W^W are designed to have] constant length, i.e.
+ *     one buffer [^W^W the frame] length is:<BR>
+ * 
+ *         320 kbps * 1152/48 kHz = 7680 bit = 960 byte
+ * 
+ *     This value is used as the maximum buffer per channel [^W^W] at
+ *     lower bitrates [than 320 kbps]. At 64 kbps mono or 128 kbps
+ *     stereo the main granule length is 64 kbps * 576/48 kHz = 768 bit
+ *     [per granule and channel] at 48 kHz sampling frequency.
+ *     This means that there is a maximum deviation (short time buffer
+ *     [= reservoir]) of 7680 - 2*2*768 = 4608 bits is allowed at 64 kbps.
+ *     The actual deviation is equal to the number of bytes [with the
+ *     meaning of octets] denoted by the main_data_end offset pointer.
+ *     The actual maximum deviation is (2^9-1)*8 bit = 4088 bits
+ *     [for MPEG-1 and (2^8-1)*8 bit for MPEG-2, both are hard limits].
+ *     ... The xchange of buffer bits between the left and right channel
+ *     is allowed without restrictions [exception: dual channel].
+ *     Because of the [constructed] constraint on the buffer size
+ *     main_data_end is always set to 0 in the case of bit_rate_index==14,
+ *     i.e. data rate 320 kbps per stereo signal [^W^W^W]. In this case
+ *     all data are allocated between adjacent header [^W sync] words
+ *     [, i.e. there is no buffering at all].

+ PSYCHO ACOUSTICS
+
+
+ This routine computes the psycho acoustics, delayed by one granule.
+
+ Input: buffer of PCM data (1024 samples).
+
+ This window should be centered over the 576 sample granule window.
+ The routine will compute the psycho acoustics for
+ this granule, but return the psycho acoustics computed
+ for the *previous* granule.  This is because the block
+ type of the previous granule can only be determined
+ after we have computed the psycho acoustics for the following
+ granule.
+
+ Output:  maskings and energies for each scalefactor band.
+ block type, PE, and some correlation measures.
+ The PE is used by CBR modes to determine if extra bits
+ from the bit reservoir should be used.  The correlation
+ measures are used to determine mid/side or regular stereo.
+ */
+/*
+ Notation:
+
+ barks:  a non-linear frequency scale.  Mapping from frequency to
+ barks is given by freq2bark()
+
+ scalefactor bands: The spectrum (frequencies) are broken into
+ SBMAX "scalefactor bands".  Thes bands
+ are determined by the MPEG ISO spec.  In
+ the noise shaping/quantization code, we allocate
+ bits among the partition bands to achieve the
+ best possible quality
+
+ partition bands:   The spectrum is also broken into about
+ 64 "partition bands".  Each partition
+ band is about .34 barks wide.  There are about 2-5
+ partition bands for each scalefactor band.
+
+ LAME computes all psycho acoustic information for each partition
+ band.  Then at the end of the computations, this information
+ is mapped to scalefactor bands.  The energy in each scalefactor
+ band is taken as the sum of the energy in all partition bands
+ which overlap the scalefactor band.  The maskings can be computed
+ in the same way (and thus represent the average masking in that band)
+ or by taking the minmum value multiplied by the number of
+ partition bands used (which represents a minimum masking in that band).
+ */
+/*
+ The general outline is as follows:
+
+ 1. compute the energy in each partition band
+ 2. compute the tonality in each partition band
+ 3. compute the strength of each partion band "masker"
+ 4. compute the masking (via the spreading function applied to each masker)
+ 5. Modifications for mid/side masking.
+
+ Each partition band is considiered a "masker".  The strength
+ of the i'th masker in band j is given by:
+
+ s3(bark(i)-bark(j))*strength(i)
+
+ The strength of the masker is a function of the energy and tonality.
+ The more tonal, the less masking.  LAME uses a simple linear formula
+ (controlled by NMT and TMN) which says the strength is given by the
+ energy divided by a linear function of the tonality.
+ */
+/*
+ s3() is the "spreading function".  It is given by a formula
+ determined via listening tests.
+
+ The total masking in the j'th partition band is the sum over
+ all maskings i.  It is thus given by the convolution of
+ the strength with s3(), the "spreading function."
+
+ masking(j) = sum_over_i  s3(i-j)*strength(i)  = s3 o strength
+
+ where "o" = convolution operator.  s3 is given by a formula determined
+ via listening tests.  It is normalized so that s3 o 1 = 1.
+
+ Note: instead of a simple convolution, LAME also has the
+ option of using "additive masking"
+
+ The most critical part is step 2, computing the tonality of each
+ partition band.  LAME has two tonality estimators.  The first
+ is based on the ISO spec, and measures how predictiable the
+ signal is over time.  The more predictable, the more tonal.
+ The second measure is based on looking at the spectrum of
+ a single granule.  The more peaky the spectrum, the more
+ tonal.  By most indications, the latter approach is better.
+
+ Finally, in step 5, the maskings for the mid and side
+ channel are possibly increased.  Under certain circumstances,
+ noise in the mid & side channels is assumed to also
+ be masked by strong maskers in the L or R channels.
+
+
+ Other data computed by the psy-model:
+
+ ms_ratio        side-channel / mid-channel masking ratio (for previous granule)
+ ms_ratio_next   side-channel / mid-channel masking ratio for this granule
+
+ percep_entropy[2]     L and R values (prev granule) of PE - A measure of how
+ much pre-echo is in the previous granule
+ percep_entropy_MS[2]  mid and side channel values (prev granule) of percep_entropy
+ energy[4]             L,R,M,S energy in each channel, prev granule
+ blocktype_d[2]        block type to use for previous granule

+     * output samplerate 4. set some options which depend on output samplerate
+     * 5. compute the actual compression ratio 6. set mode based on compression
+     * ratio
+     *
+     * The remaining code is much simpler - it just sets options based on the

+// The Module object: Our interface to the outside world. We import
+// and export values on it. There are various ways Module can be used:
+// 1. Not defined. We create it here
+// 2. A function parameter, function(Module) { ..generated code.. }
+// 3. pre-run appended it, var Module = {}; ..generated code..
+// 4. External script tag defines var Module.
+// We need to check if Module already exists (e.g. case 3 above).
+// Substitution will be replaced with actual code on later stage of the build,
+// this way Closure Compiler will not mangle it (e.g. case 4. above).
+// Note that if you want to run closure, and also to use Module
