CELT is a very low delay audio codec designed for high-quality communications.

Traditional full-bandwidth  codecs such as Vorbis and AAC can offer high
quality but they require codec delays of hundreds of milliseconds, which
makes them unsuitable  for real-time interactive applications like tele-
conferencing. Speech targeted codecs, such as Speex or G.722, have lower
20-40ms delays but their spe


Here are a few tips for building on Windows:

1) Create a config.h file that defines out things that defines out all the
   features that your compiler doesn't understand (e.g. inline, restrict).
   It also needs to define the CELT_BUILD macro

2) Define the HAVE_CONFIG_H macro in the project build options (NOT in config.h)

3) If you want things to be a lot easier, just use a compiler that suppor


- Check minimum width of bands
- Revisit energy resolution based on the bit-rate
- Revisit static bit allocation (as a function of frame size and channels)
- Dynamic adjustment of energy quantisation
- Psychacoustics
  * Error shaping within each band
  * Decisions on the rate
- Intensity stereo decisions
- Dynamic (intra-frame) bit allocation 
- Joint encoding of stereo energy

- Encode band shap
