mutagen - Python 2/3 module for handling audio metadata

•    Python

---

Mutagen is a Python module to handle audio metadata. It supports ASF, FLAC, MP4, Monkey's Audio, MP3, Musepack, Ogg Opus, Ogg FLAC, Ogg Speex, Ogg Theora, Ogg Vorbis, True Audio, WavPack, OptimFROG, and AIFF audio files. All versions of ID3v2 are supported, and all standard ID3v2.4 frames are parsed. It can read Xing headers to accurately calculate the bitrate and length of MP3s. ID3 and APEv2 tags can be edited regardless of audio format. It can also manipulate Ogg streams on an individual packet/page level. Mutagen works with Python 2.7, 3.4+ (CPython and PyPy) on Linux, Windows and macOS, and has no dependencies outside the Python standard library. Mutagen is licensed under the GPL version 2 or later.

libnyquist - :microphone: Cross platform, C++11 interface to audio decoding

•    C++

---

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 or GPL license encumbered formats (such as MP3 and 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.

superfast - :zap: SuperFast codecs for fre:ac

•    C

---

This repository provides multi-threaded MP3, AAC, Opus and Speex codec drivers for use with the fre:ac audio converter. The components use multiple instances of the respective codecs in parallel to provide faster processing on systems with multiple CPU cores. The idea to use multiple codec instances to speed-up audio encoding goes back to 2006 when the LAME MT project tried to build a multi-threaded MP3 encoder. This project picks up the original idea behind LAME MT and takes it to AAC, Opus and Speex encoding in addition to MP3.
