libaudec

builds.sr.ht status

libaudec (lib audio decoder) is a wrapper library over minimp3, 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)

libaudec supports all formats supported by sndfile, in addition to MP3.

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.
