[![builds.sr.ht status](https://builds.sr.ht/~alextee/zrythm.svg)](https://builds.sr.ht/~alextee/libaudec?)

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 ` 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.
