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

Fluid-3 is Frank Wen's pro-quality GM soundfont.

TwoLAME is an optimised MPEG Audio Layer 2 (MP2) encoder based on tooLAME by Mike Cheng, which in turn is based upon the ISO dist10 code and portions of LAME.

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.

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.

python-pysox is a wrapper around the sox command line tool. The API offers Transformer and Combiner classes that allow the user to incrementally build up effects and audio manipulations. python-pysox also provides methods for querying audio information such as sample rate, determining whether an audio file is silent, and much more.

libdjinterop is a C++ library that allows access to database formats used to store information about DJ record libraries.

The Bauer stereophonic-to-binaural DSP (bs2b) library and plugins is designed to improve headphone listening of stereo audio records. Recommended for headphone prolonged listening to disable superstereo fatigue without essential distortions.

This project is a rebirth of a direct integration between Bluez and ALSA. Since Bluez >= 5, the built-in integration has been removed in favor of 3rd party audio applications. From now on, Bluez acts as a middleware between an audio application, which implements Bluetooth audio profile, and a Bluetooth audio device. BlueALSA registers all known Bluetooth audio profiles in Bluez, so in theory every Bluetooth device (with audio capabilities) can be connected. In order to access the audio stream, one has to connect to the ALSA PCM device called bluealsa. The device is based on the ALSA software PCM plugin.

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

Autotalent is a LADSPA plugin for real-time pitch-correction. Among its controls are allowable notes, strength of correction, LFO for vibrato and formant warp.

LV2 is an open specification for audio plugins and host applications. At its core, LV2 is a simple stable interface, accompanied by extensions which add functionality to support the needs of increasingly powerful audio software.

Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. Ecasound supports a wide range of audio inputs, outputs and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console mode user-interface is included in the package.

This C library provides an encoder and a decoder for the GSM 06.10 RPE-LTP lossy speech compression algorithm.

Lilv is a C library to make the use of LV2 plugins as simple as possible for applications. Lilv is the successor to SLV2, rewritten to be significantly faster and have minimal dependencies.

This package provides a barebones, fast LV2 bass enhancement plugin.

Gnaural is a programmable auditory binaural beat synthesizer intended to be used for brainwave entrainment. Gnaural supports creation of binaural beat tracks of different frequencies and exporting of tracks into different audio formats. Gnaural can also be linked over the internet with other Gnaural instances, allowing synchronous sessions between many users.

Codec 2 is a speech codec designed for communications quality speech between 700 and 3200 bit/s. The main application is low bandwidth HF/VHF digital radio.

WildMIDI is a simple software midi player which has a core softsynth library that can be used with other applications.

Guitarix is a virtual guitar amplifier running JACK. Guitarix takes the signal from your guitar as a mono-signal from your sound card. The input is processed by a main amp and a rack-section. Both can be routed separately and deliver a processed stereo-signal via JACK. You may fill the rack with effects from more than 25 built-in modules including stuff from a simple noise gate to modulation effects like flanger, phaser or auto-wah.

The AMB plugins are a set of LADSPA ambisonics plugins, mainly to be used within Ardour. Features include: mono and stereo to B-format panning, horizontal rotator, square, hexagon and cube decoders.

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.

SoX (Sound eXchange) is a command line utility that can convert various formats of computer audio files to other formats. It can also apply various effects to these sound files, and, as an added bonus, SoX can play and record audio files.

The Bauer stereophonic-to-binaural DSP (bs2b) library and plugins is designed to improve headphone listening of stereo audio records. Recommended for headphone prolonged listening to disable superstereo fatigue without essential distortions. This package contains a LADSPA plugin for use with applications that support them (e.g. PulseAudio).
