This package provides a LADSPA plugin to manipulate the stereo width of audio signals.

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

TTA performs lossless compression on multichannel 8,16 and 24 bits data of the Wav audio files. Being lossless means that no data- quality is lost in the compression - when uncompressed, the data will be identical to the original. The compression ratios of TTA depend on the type of music file being compressed, but the compression size will generally range between 30% - 70% of the original. TTA format supports both of ID3v1/v2 and APEv2 tags.

Cubeb is Mozilla's cross-platform audio library.

libaudec is a wrapper library over ffmpeg, sndfile and libsamplerate for reading and resampling audio files, based on Robin Gareus' audio_decoder code.

python-resampy implements the band-limited sinc interpolation method for sampling rate conversion as described by Julius O. Smith at the Digital Audio Resampling Home Page.

An LV2 port of the mda EPiano VSTi.

FreePats is a project to create a free (as in free software) collection of digital instruments for music production. This sound bank is a partial release of the General MIDI sound set.

Suil is a lightweight C library for loading and wrapping LV2 plugin UIs.

Suil makes it possible to load a UI of a toolkit in a host using another toolkit. The API is designed such that hosts do not need to explicitly support specific toolkits – if Suil supports a particular toolkit, then UIs in that toolkit will work in all hosts that use Suil automatically.

Suil currently supports every combination of Gtk, Qt, and X11.

This package provides a simple sound library for C++.

cli-visualizer displays fast-Fourier transforms (FFTs) of the sound being played, as well as other graphical representations.

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.

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.

This package provides a JACK Audio Connection Kit (JACK) client for Python. This variant uses the compatibility JACK implementation provided by Pipewire.

This package provides libshout plus IDJC extensions.

This package contains wrappers for accessing the ALSA API from Python. It is currently fairly complete for PCM devices, and has some support for mixers.

Pyliblo is a Python wrapper for the liblo Open Sound Control (OSC) library. It supports almost the complete functionality of liblo, allowing you to send and receive OSC messages using a nice and simple Python API. Also included are the command line utilities send_osc and dump_osc.

FreePats is a project to create a free and open set of GUS compatible patches that can be used with softsynths such as Timidity and WildMidi.

LADSPA is a standard that allows software audio processors and effects to be plugged into a wide range of audio synthesis and recording packages.

libsoundio is a C library providing audio input and output. The API is suitable for real-time software such as digital audio workstations as well as consumer software such as music players.

This package provides pythonic libsndfile wrapper to read and write audio files.

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

This package provides a LADSPA plugin for a stereo reverb effect.

The infamous plugins are a collection of LV2 audio plugins for live performances. The plugins include a cellular automaton synthesizer, an envelope follower, distortion effects, tape effects and more.
