- 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

- Long-term quality improvements
- -Improve perceptual enhancement (including wideband)
- Standards
- -Complete Speex RTP profile
- -MIME type registration
- ideas:
- Peelable stream (double codebook, higher bands, stereo)
