Control a Jack server. Allows you to plug various sources into various outputs and to start, stop and configure jackd

This package provides a Python high-level interface and ctypes-based bindings for PulseAudio (libpulse), to use in simple synchronous code. This wrapper is mostly for mixer-like controls and introspection-related operations, as opposed to e.g. submitting sound samples to play and player-like clients.

SoundTouch is an audio processing library for changing the tempo, pitch and playback rates of audio streams or audio files. It is intended for application developers writing sound processing tools that require tempo/pitch control functionality, or just for playing around with the sound effects.

freealut is the OpenAL Utility Toolkit.

redumper is a low-level byte perfect CD disc dumper. It supports incremental dumps, advanced SCSI/C2 repair, intelligent audio CD offset detection, among other features. redumper is also a general purpose DVD/HD-DVD/Blu-ray disc dumper.

Ableton Link is a C++ library that synchronizes musical beat, tempo, and phase across multiple applications running on one or more devices. Applications on devices connected to a local network discover each other automatically and form a musical session in which each participant can perform independently: anyone can start or stop while still staying in time.

This Python module provides bindings for the PortAudio library and a few convenience functions to play and record NumPy arrays containing audio signals.

audio-to-midi converts audio files to multichannel MIDI files. It accomplishes this by performing FFTs on all channels of the audio data at user-specified time steps. It then separates the resulting frequency analysis into equivalence classes which correspond to the twelve tone scale; the volume of each class being the average volume of its constituent frequencies. This data is then formatted to MIDI and written to disk.

LibTiMidity is a MIDI to WAVE converter library that uses Gravis Ultrasound-compatible patch files to generate digital audio data from General MIDI files.

SoundTouch is an audio processing library for changing the tempo, pitch and playback rates of audio streams or audio files. It is intended for application developers writing sound processing tools that require tempo/pitch control functionality, or just for playing around with the sound effects.

The Portable C Audio Library (pcaudiolib) provides a C API to different audio devices such as ALSA or PulseAudio.

Calf Studio Gear is an audio plug-in pack for LV2 and JACK environments. The suite contains lots of effects (delay, modulation, signal processing, filters, equalizers, dynamics, distortion and mastering effects), instruments (SF2 player, organ simulator and a monophonic synthesizer) and tools (analyzer, mono/stereo tools, crossovers).

FluidSynth is a real-time software synthesizer based on the SoundFont 2 specifications. FluidSynth reads and handles MIDI events from the MIDI input device. It is the software analogue of a MIDI synthesizer. FluidSynth can also play midifiles using a Soundfont.

This package provides libshout plus IDJC extensions.

siggen is a set of tools for imitating a laboratory signal generator, generating audio signals out of Linux's /dev/dsp audio device. There is support for mono and/or stereo and 8 or 16 bit samples.

LibOFA is an audio fingerprint library, created and provided by MusicIP.

This package provides bindings for PortAudio v19, the cross-platform audio input/output stream library.

Snapcast is a multi-room client-server audio player. Clients are time synchronized with the server to play synced audio.

Copies a stream, skipping everything except MP3 frames with valid headers. This can be used to copy and concatenate streams, even if they contain extra garbage.

Snd is a sound editor modelled loosely after Emacs. It can be customized and extended using either the s7 Scheme implementation (included in the Snd sources), Ruby, or Forth.

Xmp is a portable module player that plays over 90 mainstream and obscure module formats, including Protracker MOD, Fasttracker II XM, Scream Tracker 3 S3M and Impulse Tracker IT files.

BS1770GAIN is a loudness scanner compliant with ITU-R BS.1770 and its flavors EBU R128, ATSC A/85, and ReplayGain 2.0. It helps normalizing the loudness of audio and video files to the same level.

RtMidi is a set of C++ classes (RtMidiIn, RtMidiOut, and API specific classes) that provide a common cross-platform API for realtime MIDI input/output.

libkeyfinder is a small C++11 library for estimating the musical key of digital audio.
