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

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.

DarkIce is a live audio streamer. It takes audio input from a sound card, encodes it into Ogg Vorbis and/or mp3, and sends the audio stream to one or more IceCast and/or ShoutCast servers.

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

Dexed is a multi-platform, multi-format plugin synthesizer. The sound engine is closely modeled on the original Yamaha DX7 characteristics. Dexed is also a MIDI cartridge librarian/manager for the DX7. Features include:

1. 144 DAW automatable DX7 parameters available from one single panel;

2. It fully supports DX7 input and output Sysex messages; including controller change. This means that you can use this with a native DX7/TX7 as a patch editor and sysex manager.

3. Every FM operator has a realtime VU meter to know which one is active.

4. It can load/save any DX7/TX7 sysex programs. It is also possible to save a single program into a different sysex file.

Dexed can be configured to use some of the original math limitation of a DX synthesizer. This does not only apply to the DAC, it also involves the bit resolution of the sine waves and the way that the amplitude is applied to each operator. Dexed comes with three engine types:

1. Modern: this is the original 24-bit implementation.

2. Mark I: Based on the OPL Series but at a higher resolution (LUT are 10-bits). The target of this engine is to be closest to the real DX7.

3. OPL Series: this is an experimental 8-bit implementation of the reversed engineered OPL family chips.

wp-notifyd is a lightweight notification daemon for WirePlumber (the session and policy manager for PipeWire).

Rakarrack is a richly featured multi-effects processor emulating a guitar effects pedalboard. Effects include compressor, expander, noise gate, equalizers, exciter, flangers, chorus, various delay and reverb effects, distortion modules and many more. Most of the effects engine is built from modules found in the excellent software synthesizer ZynAddSubFX. Presets and user interface are optimized for guitar, but Rakarrack processes signals in stereo while it does not apply internal band-limiting filtering, and thus is well suited to all musical instruments and vocals.

clalsadrv is a C++ wrapper around the ALSA API simplifying access to ALSA PCM devices.

LV2 port of CAPS, a collection of audio plugins comprising basic virtual guitar amplification and a small range of classic effects, signal processors and generators of mostly elementary and occasionally exotic nature.

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

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

yabridge is Yet Another way to use Windows audio plugins. It supports using Windows VST2, VST3, and CLAP plugins in plugin hosts as if they were native plugins, with optional support for plugin groups to enable inter-plugin communication for VST2 plugins and quick startup times.

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.

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

The LV2 Toolkit (LVTK) contains libraries that wrap the LV2 C API and extensions into easy to use C++ classes. It is the successor of lv2-c++-tools.

This is a PyQT GUI application to dynamically modify Pipewire and Wireplumber settings at runtime, such as quantum. sample rate, latency offset setting, services restart and more. It features side-by-side and graph style connections manager, pw-top wrapper, simple ALSA mixer and jack_delay GUI.

RtAudio is a set of C++ classes that provides a common API for real-time audio input/output. It was designed with the following objectives:

• object-oriented C++ design

• simple, common API across all supported platforms

• only one source and one header file for easy inclusion in programming projects

• allow simultaneous multi-api support

• support dynamic connection of devices

• provide extensive audio device parameter control

• allow audio device capability probing

• automatic internal conversion for data format, channel number compensation, (de)interleaving, and byte-swapping

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.

Redkite is a small GUI toolkit developed in C++17 and inspired from other well known GUI toolkits such as Qt and GTK. It is minimal on purpose and is intended to be statically linked to applications, therefore satisfying any requirements they may have to be self contained, as is the case with audio plugins.

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.

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.

RaySession is a session manager for audio programs such as Ardour, Carla, QTractor, Guitarix, Patroneo, Jack Mixer, etc. The principle is to load together audio programs, then be able to save or close all documents together. Its main purpose is to manage NSM compatible programs, but it also helps for other programs. It offers a patchbay for visualizing and editing connections.

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

fmsynth is an LV2 plugin which implements an FM (Frequency Modulation) synthesizer. Unlike most FM synth implementations in software, this FM synthesizer does not aim to emulate or replicate a particular synth (like DX7) or FM chip.
