New release of racket-audio

[hnmdijkema]

I just release a new version of module racket-audio. It now also works with ffmpeg as backend and there's no special C-layer necessary anymore. The needed audio libraries are used directly.

For windows the needed DLL's are still downloaded though. On linux the libraries are expected to be installed (e.g. using apt). On MacOSx one needs to install the needed libraries using homebrew.

This module need following libraries:

• xiph libao (https://xiph.org).
• xiph libFLAC (https://xiph.org).
• ffmpeg of the right version, currently ffmpeg 6.x t/m 8.x are supported (https://ffmpeg.org).
• libmpg123 (https://mpg123.org).

A good interface to ffmpeg's libav* libraries would be a nice thing to have in Racket. Maybe this is a start!

I wouldn't count on that. This module is fully focused on using ffmpeg for audio decoding. It uses the bare minimum of ffmpeg definitions / functions for it's purpose.
