Better saturation handling in mdf?
get rid of crap that shouldn't be exposed in speex.h
For 1.2:
Major points:
- Make documentation match the actual code (especially jitter buffer, AEC and preprocessor)
- Get AGC to work in fixed-point even if not totally converted
- Stabilise all APIs (need feedback)
- Short-term estimate in jitter buffer
- Control delay in new AEC API.
- NaN checks?
- Better error reporting
- Make kiss-fft 32-bit safe
Minor issues:
- Fix last frame of speexenc
Post 1.2:
improve float<->int conversion
split encoder and decoder?
Merge TriMedia stuff
packet dump
Do VAD properly
--enable-{aec,preprocessor,jitter,resampler}
Optimisations
- Add restrict in a few places?
- enable 4x4 version of pitch_xcorr() at least on some archs?
- use __builtin_expect() (likely()/unlikely())
Would be nice:
Implement wideband split as IIR instead of QMF?
Allocator override (speex_lib_ctl)
Better error handling
Allocator override (speex_lib_ctl?)
Fixed-point:
- Wideband
- Initialization
- VBR
- Jitter buffer
- AGC
Denoiser:
- Smooth gain (remove musical noise)
- Better noise adaptation
- Do some tuning
AGC:
- Use median filtering instead of "non-linear mean"
Features
-Add maximum/minimum bit-rate control for VBR
-Improve error handling (with perror-like call?)
Long-term quality improvements
-Improve perceptual enhancement (including wideband)
- Use median filtering instead of "non-linear mean"?
Standards
-Complete Speex RTP profile

ideas:
Peelable stream (double codebook, higher bands, stereo)
LPC from spectral domain
Better psycho-acoustic model. Masking curve from Vorbis?

@brief Pseudo-floating point
* This header file provides a lightweight floating point type for
* use on fixed-point platforms when a large dynamic range is
* required. The new type is not compatible with the 32-bit IEEE format,
* it is not even remotely as accurate as 32-bit floats, and is not
* even guaranteed to produce even remotely correct results for code
* other than Speex. It makes all kinds of shortcuts that are acceptable
* for Speex, but may not be acceptable for your application. You're
* quite welcome to reuse this code and improve it, but don't assume
* it works out of the box. Most likely, it doesn't.
