New page

Opus-tools is a collection of tools for working with opus files currently under development.

==Features==

===Encoder===
* Robust wav input (steal battle tested code from oggenc, e.g. float and multichannel works)
* Resampling
* bitrate selection
* VBR/CBR/CVBR
* Application selection (audio/voip)
* Mode forcing
* Metadata (emulate oggenc feature set)
* Multichannel
* Not needed in initial release:
** Exposes all sanely exposable parts of the Opus API (important for testing, even if things are hidden)
** Flac input (?; code for this is in oggenc)

===Decoder===
* Resampling
* Multichannel
* metadata display
* Wav output
* audio playback (libao?) or omit and leave for ogg123
* Not needed for the initial release:
** Limiter (copy from postfish)
** Dither for 16 bit output
