NI Media is a C++ library for reading and writing audio streams.

A library for audio and music analysis, feature extraction.

Free, easy, portable audio engine for games

miniaudio is a single-file C audio library used for audio playback, capture, and hardware interfacing across multiple operating systems. It functions as an audio hardware abstraction layer, an audio processing engine, an audio synthesis engine, and a codec and resampler. The project implements a node-graph based system for routing digital audio signals, mixing, and 3D spatialization. It also includes a programmatic generator for noise patterns and basic waveforms used for sound creation and signal testing. The library covers digital signal processing, including audio format conversion and sa

🎵 Music notation engraving library for MEI with MusicXML and Humdrum support and various toolkits (JavaScript, Python)

rnnoise is a real-time speech denoising library that uses a recurrent neural network to suppress background noise from live voice audio. It is implemented as a lightweight C library with a minimal API, designed for easy integration into audio applications that need low-latency noise reduction. The library employs a gated recurrent unit (GRU) architecture and frequency-domain feature extraction to capture temporal dependencies in speech, operating on short audio frames sequentially for streaming use. It also includes a training pipeline that allows users to train custom noise suppression model

Easy and efficient audio synthesis in C++

SimplE Lossless Audio

C library for cross-platform real-time audio input and output

Minimalistic MP3 decoder single header library

A C library for reading and writing sound files containing sampled audio data.

This is a header-only library, as such most of its functional documentation is contained within the "header section" of the source code in the form of comments. It is highly recommended that you read said documentation before using this library.

Painless high-performance audio on iOS and Mac OS X

PocketSphinx is an offline speech recognition engine that converts raw audio from files or live microphone streams into written text without requiring a network connection. It functions as a speech-to-text library, a real-time transcription engine, and a voice command processor, capable of detecting and transcribing spoken commands from continuous audio streams with configurable acoustic and language models. The engine uses weighted finite-state transducers to represent acoustic, phonetic, and language models as a single search graph for efficient decoding. It employs fixed-point acoustic mod

Rhythm Trainer based on the idea of users snapping their fingers while listening to music. Won Apple's Global WWDC23 Swift Student Challenge.

AudioKit is an audio framework for iOS, macOS, and tvOS that provides tools for digital audio synthesis, signal processing, and audio analysis. It functions as a synthesis engine for generating audio waveforms and textures, a processing library for modifying tonal characteristics, and a toolkit for extracting frequency and amplitude data from sonic signals. The framework utilizes a modular node architecture and graph-based signal routing to connect audio generators, processors, and outputs. It wraps low-level audio primitives in high-level classes to facilitate sound generation and modificati

🎵 ID3 decoding and encoding library for Go

This is a single-file library for resampling audio. It is written in C89 and licensed under the terms of the Zero-Clause BSD licence.

alto provides idiomatic Rust bindings for OpenAL 1.1 and extensions (including EFX).

GAAD (Go Advanced Audio Decoder)

Expressive Digital Signal Processing (DSP) package for Python

Spleeter is an AI audio source separation library and deep learning toolkit designed to split mixed music files into individual audio stems, such as vocals and drums. It provides a suite of pretrained models for isolating different instruments and voices from a recording. The toolkit includes capabilities for training and evaluating custom audio separation models using labeled datasets and configuration files. It also features utilities for measuring model performance by comparing separation outputs against reference datasets. The system manages audio processing through spectral representati

AudioPlayer is syntax and feature sugar over AVPlayer. It plays your audio files (local & remote).

🅿️ PandoraPlayer is a lightweight music player for iOS, based on AudioKit and completely written in Swift.
