This package provides libshout plus IDJC extensions.

Qsynth is a GUI front-end application for the FluidSynth SoundFont synthesizer written in C++.

RNNoise is a library that uses deep learning to apply noise suppression to audio sources with voice presence. This package provides an LV2 audio plugin.

CLAP stands for CLever Audio Plugin. It is an audio plugin ABI which defines a standard for Digital Audio Workstations and audio plugins to work together.

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.

The LSP DSP library provides a set of functions that perform SIMD-optimized computing on several hardware architectures. All functions currently operate on IEEE-754 single-precision floating-point numbers.

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.

SBSMS (Subband Sinusoidal Modeling Synthesis) is software for time stretching and pitch scaling of audio. This package contains the library.

Cuetools is a set of programs that are useful for manipulating and using CUE sheet (cue) files and Table of Contents (toc) files. CUE and TOC files are a way to represent the layout of a data or audio CD in a machine-readable ASCII format.

This package provides a command-line AAC-encoder.

RSound allows you to send audio from an application and transfer it directly to a different computer on your LAN network. It is an audio daemon with a much different focus than most other audio daemons.

yabridgectl is a tool to setup and update yabridge.

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

Faust is a programming language for realtime audio signal processing.

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

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

An LV2 port of the mda EPiano VSTi.

VO-AACENC is the VisualOn implementation of Advanced Audio Coding (AAC) encoder.

SuperCollider is a synthesis engine (scsynth or supernova) and programming language (sclang). It can be used for experimenting with sound synthesis and algorithmic composition.

SuperCollider requires jackd to be installed in your user profile and your user must be allowed to access the realtime features of the kernel. Search for "realtime" in the index of the Guix manual to learn how to achieve this using Guix System.

libfreeaptx is an implementation of the Audio Processing Technology codecs aptX and aptX HD, mainly intended for use with an A2DP bluetooth profile.

Csound is a user-programmable and user-extensible sound processing language and software synthesizer.

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

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

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.
