# 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).
|
||||
|
||||
Platform | Build Status |
|
||||
-------- | ------------ |
|
||||
Microsoft VS2017 x64 | [](https://ci.appveyor.com/project/ddiakopoulos/libnyquist) |

|
||||
|
||||
Libnyquist is a small C++11 library for reading sampled audio data from disk or memory. It is intended to be used an audio loading frontend for games, audio sequencers, music players, and more.
|
||||
|
||||
The library does not include patent or license encumbered formats (such as AAC). For portability, libnyquist does not link against platform-specific APIs like Windows Media Foundation or CoreAudio, and instead bundles the source code of reference decoders as an implementation detail.
|
||||
|
||||
Libnyquist is meant to be statically linked, which is not the case with other popular libraries like libsndfile (which is licensed under the LGPL). Furthermore, the library is not concerned with supporting very rare encodings (for instance, A-law PCM or the SND format).
|
||||
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 produces a channel-interleaved float vector, normalized between [-1.0,+1.0]. At present, the library does not provide comprehensive resampling functionality.

System Requirements:
|
||||
|
||||
- MIDI Playback Software capable of reading Type 1 Standard
|
||||
MIDI File format
|
||||
- General MIDI sound device (Wave Table recommended.)
|
||||
|
||||
|
||||
This Standard MIDI File was recorded directly from LucasFilm Game's
|
||||
"The Secret of Monkey Island" adventure game. It has been converted
|
||||
from the MT-32 version for playback on General MIDI sound cards. A
|
||||
Wave Table sound card is highly recommended for optimal playback.
|
||||
|
||||
Recorded/Converted to Standard MIDI File format by Tom Lewandowski.
