Libnyquist

Libnyquist is a small C++11 library for reading sampled audio data from disk or memory. It's ideal to use as an audio asset frontend for games, audio sequencers, music players, and more.

The library steers away from patent-encumbered formats and those with non-BSD licensed codec implementations (such as MP3 and AAC, respectively).

Libnyquist is meant to be statically linked, which is not the case with other popular libraries like libsndfile (LGPL). Furthermore, the library is not concerned with legacy format support (for instance, A-law PCM encoding or SND files).

While untested, there are no technical conditions that preclude compilation on other platforms with C++11 support (Android NDK r10e+, Linux, iOS, etc).

Format Support

Regardless of input bit depth, the library hands over an interleaved float array, normalized between [-1.0,+1.0]. At present, the library does not provide resampling functionality.

Wave
Ogg Vorbis
Ogg Opus
FLAC
WavPack
Musepack
Core Audio Format (Apple Lossless / AIFF) (WIP)

Supported Project Files

Visual Studio 2013
XCode 6

Known Issues

Ogg and Opus have conflicting mdct files. Their sources were modified such that they compile cleanly together in the same project.
Streaming is not supported for any file formats.

Encoding

Simple but robust WAV format encoder now included. Extentions in the near future might include Ogg.

License

Libyquist is released under the 2-Clause BSD license. All dependencies and codecs are under similar open licenses.
