Libcava is a soft fork of CAVA that additionally builds and installs CAVA as a reusable shared library. It provides the public headers and pkg-config metadata needed by applications that embed CAVA's real-time audio analysis.

The Odio SACD shared library is a decoding engine which takes a Super Audio CD source and extracts a 24-bit high resolution WAV file. It handles both DST and DSD streams.

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.

Jalv is a simple but fully featured LV2 host for JACK. It runs LV2 plugins and exposes their ports as JACK ports, essentially making any LV2 plugin function as a JACK application.

MDA-LV2 is an LV2 port of the MDA plugins. It includes effects and a few instrument plugins.

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

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.

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.

VO-AMR is a library of VisualOn implementation of Adaptive Multi Rate Narrowband and Wideband (AMR-NB and AMR-WB) speech codec.

Tenacity is a multi-track audio editor designed for recording, playing and editing digital audio. It features digital effects and spectrum analysis tools.

EasyEffects is an advanced audio manipulation tool providing a graphical user interface to apply various effects and filters to audio streams using Pipewire. Effects can be applied in real time to audio inputs or outputs such as a microphone to reduce noise or apply many other effects including:

• Auto gain

• Bass enhancer

• Bass loudness

• Compressor

• Convolver

• Crossfeed

• Crystalizer

• De-esser

• Delay

• Echo Canceller

• Equalizer

• Exciter

• Filter (low-pass, high-pass, band-pass and band-reject modes)

• Gate

• Limiter

• Loudness

• Maximizer

• Multiband compressor

• Multiband gate

• Noise reduction

• Pitch

• Reverberation

• Speech Processor

• Stereo tools

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

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.

Dcadec is a DTS Coherent Acoustics surround sound decoder with support for HD extensions.

yabridgectl is a tool to setup and update yabridge.

An LV2 port of the mda EPiano VSTi.

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

Tao is a software package for sound synthesis using physical models. It provides a virtual acoustic material constructed from masses and springs which can be used as the basis for building quite complex virtual musical instruments. Tao comes with a synthesis language for creating and playing instruments and a C++ API for those who would like to use it as an object library.

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.

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.

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.

ALURE is a utility library to help manage common tasks with OpenAL applications. This includes device enumeration and initialization, file loading, and streaming.

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.
