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 tools for managing JACK connections and testing or configuring the JACK session. Tools include jack_lsp, jack_connect, and jack_transport.

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

The pa-notify daemon sends notifications about the current volume level of PulseAudio or PipeWire using libnotify.

This package provides a LADSPA plugin for a four-band parametric equalizer. Each section has an active/bypass switch, frequency, bandwidth and gain controls. There is also a global bypass switch and gain control.

The 2nd order resonant filters are implemented using a Mitra-Regalia style lattice filter, which is stable even while parameters are being changed.

All switches and controls are internally smoothed, so they can be used live without any clicks or zipper noises. This makes this plugin suitable for use in systems that allow automation of plugin control ports, such as Ardour, or for stage use.

JackTrip is a multi-machine audio system used for network music performance over the Internet. It supports any number of channels (as many as the computer/network can handle) of bidirectional, high quality, uncompressed audio signal streaming.

The SoX Resampler library (libsoxr) performs one-dimensional sample-rate conversion. It may be used, for example, to resample PCM-encoded audio.

AlsaModularSynth is a digital implementation of a classical analog modular synthesizer system. It uses virtual control voltages to control the parameters of the modules. The control voltages which control the frequency e.g. of the VCO (Voltage Controlled Oscillator) and VCF (Voltage Controlled Filter) modules follow the convention of 1V / Octave.

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.

DRC is a program used to generate correction filters for acoustic compensation of HiFi and audio systems in general, including listening room compensation. DRC generates just the FIR correction filters, which can be used with a real time or offline convolver to provide real time or offline correction. DRC doesn't provide convolution features, and provides only some simplified, although really accurate, measuring tools.

OpenShot Audio Library (libopenshot-audio) allows high-quality editing and playback of audio, and is based on the JUCE library.

FAudio is an XAudio reimplementation that focuses solely on developing fully accurate DirectX Audio runtime libraries.

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 package provides python bindings for libsndfile based on CFFI and NumPy.

Libmixed is a library for real-time audio processing pipelines for use in audio/video/games. It can serve as a base architecture for complex DSP systems.

This package provides libshout plus IDJC extensions.

shntool is a multi-purpose WAVE data processing and reporting utility. File formats are abstracted from its core, so it can process any file that contains WAVE data, compressed or not---provided there exists a format module to handle that particular file type. It can also generate CUE files, and use them split WAVE data into multiple files.

Libltc is a POSIX-C Library for handling Linear/Longitudinal Time Code (LTC) data.

lv2lint is an LV2 lint-like tool that checks whether a given plugin and its UI(s) match up with the provided metadata and adhere to well-known best practices.

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.

WavPack is an audio compression format with lossless, lossy and hybrid compression modes. This package contains command-line programs and library to encode and decode wavpack files.

This package provides various LADSPA plugins. cs_chorus and cs_phaser provide chorus and phaser effects, respectively; mvclpf24 provides four implementations of the low-pass filter used in vintage Moog synthesizers; mvchpf24 is based on the voltage-controlled high-pass filter by Robert Moog. The filters attempt to accurately emulate the non-linear circuit elements of their original analog counterparts.

AZR-3 is a port of the free VST plugin AZR-3. It is a tonewheel organ with drawbars, distortion and rotating speakers. The organ has three sections, two polyphonic sections with nine drawbars each and one monophonic bass section with five drawbars. A standalone JACK application and LV2 plugins are provided.

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