3 - Make documentation match the actual code (especially jitter buffer, AEC and preprocessor)
4 - Get AGC to work in fixed-point even if not totally converted
5 - Stabilise all APIs (need feedback)
6 - Short-term estimate in jitter buffer
7 - Control delay in new AEC API.
9 - Better error reporting
10 - Make kiss-fft 32-bit safe
13 - Fix last frame of speexenc
17 improve float<->int conversion
18 split encoder and decoder?
22 --enable-{aec,preprocessor,jitter,resampler}
25 - Add restrict in a few places?
26 - enable 4x4 version of pitch_xcorr() at least on some archs?
27 - use __builtin_expect() (likely()/unlikely())
30 Implement wideband split as IIR instead of QMF?
32 Allocator override (speex_lib_ctl?)
38 - Better noise adaptation
40 - Use median filtering instead of "non-linear mean"?
43 -Complete Speex RTP profile
44 -MIME type registration
47 Peelable stream (double codebook, higher bands, stereo)
48 LPC from spectral domain
