-//	Implementation Summary
-//
-//	1. Enforce API surface and semantic compatibility with 1.9.x branch
-//	2. Improve the module's maintainability by reducing the storage
-//		paths to a single mechanism.
-//	3. Use the same single mechanism to support "private" and "user" data.
-//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
-//	5. Avoid exposing implementation details on user objects (eg. expando properties)
-//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

- *
- *  as many times as you want, with as many or as few samples as you want.
- *  If mono, pass the sample buffer in through left_samples, leave
- *  right_samples NULL, and make sure num_channels = 1.
- *
- *    GetTitleGain()
- *
- *  will return the recommended dB level change for all samples analyzed
- *  SINCE THE LAST TIME you called GetTitleGain() OR InitGainAnalysis().
- *
- *    GetAlbumGain()
- *
- *  will return the recommended dB level change for all samples analyzed
- *  since InitGainAnalysis() was called and finalized with GetTitleGain().
- *
- *  Pseudo-code to process an album:
- *
- *    Float_t       l_samples [4096];
- *    Float_t       r_samples [4096];

-/*
- *  So here's the main source of potential code confusion:
- *
- *  The filters applied to the incoming samples are IIR filters,
- *  meaning they rely on up to <filter order> number of previous samples
- *  AND up to <filter order> number of previous filtered samples.
- *
- *  I set up the AnalyzeSamples routine to minimize memory usage and interface
- *  complexity. The speed isn't compromised too much (I don't think), but the
- *  internal complexity is higher than it should be for such a relatively
- *  simple routine.

- * 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

-     * We first have some complex code to determine bitrate, output samplerate
-     * and mode. It is complicated by the fact that we allow the user to set
-     * some or all of these parameters, and need to determine best possible
-     * values for the rest of them:
-     *
-     * 1. set some CPU related flags 2. check if we are mono.mono, stereo.mono
-     * or stereo.stereo 3. compute bitrate and output samplerate: user may have
-     * set compression ratio user may have set a bitrate user may have set a
-     * 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
-     * mode & compression ratio:
-     *
-     * set allow_diff_short based on mode select lowpass filter based on
-     * compression ratio & mode set the bitrate index, and min/max bitrates for
-     * VBR modes disable VBR tag if it is not appropriate initialize the
-     * bitstream initialize scalefac_band data set sideinfo_len (based on
-     * channels, CRC, out_samplerate) write an id3v2 tag into the bitstream
-     * write VBR tag into the bitstream set mpeg1/2 flag estimate the number of
-     * frames (based on a lot of data)
-     *
-     * now we set more flags: nspsytune: see code VBR modes see code CBR/ABR see
-     * code
