libaudec

libaudec (lib audio decoder) is a wrapper library over ffmpeg, sndfile and libsamplerate for reading and resampling audio files, based on Robin Gareus' audio_decoder code (https://github.com/x42/silan/tree/master/audio_decoder)

This library is meant to be linked in statically to larger projects.

Until version 1.0 is released, the API is subject to change.

Usage

Use #include <audec/audec.h> in your C/C++ project and add a dependency to the library using the pkg-config name audec.

Example of loading a file into an interleaved float array at 44000Hz:

AudecInfo nfo;
AudecHandle * handle =
  audec_open (filename, &nfo);
if (!handle)
  {
    /* handle error */
  }
float * out_frames = NULL;
ssize_t samples_read =
  audec_read (
    handle, &out_frames, 44000);
if (samples_read < 0)
  {
    /* handle error */
  }
audec_close (handle);

See the header file for more info.
