Discussion page regarding the rework of the ffmpeg audio api to acomodate the requirements needed for todays audio codecs.
Features needed
- Generalized downmixing (simd optimized)
- Output channel request function (ie, request a specified number of channels, default should be >2 mapped to 2 channels)
- Optimized interleaving
- Allow planer output, (don't duplicate interleaving code in every codec)
- Add support for other bitdepths then 16bits
- Add a better fft routine, maybe the KISS one
- Fixedpoint mdct/fft functions
