IR is a low-latency, real-time, high performance signal convolver especially for creating reverb effects. It supports impulse responses with 1, 2 or 4 channels, in any soundfile format supported by libsndfile.

Rubber Band is a library and utility program that permits changing the tempo and pitch of an audio recording independently of one another.

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.

Calf Studio Gear is an audio plug-in pack for LV2 and JACK environments. The suite contains lots of effects (delay, modulation, signal processing, filters, equalizers, dynamics, distortion and mastering effects), instruments (SF2 player, organ simulator and a monophonic synthesizer) and tools (analyzer, mono/stereo tools, crossovers).

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

lv2toweb allows the user to create an xhtml page with information about the given LV2 plugin, provided that the plugin and its UI(s) match up with the provided metadata and adhere to well-known best practices.

LibTiMidity is a MIDI to WAVE converter library that uses Gravis Ultrasound-compatible patch files to generate digital audio data from General MIDI files.

Odio SACD is a command-line application which takes a Super Audio CD source and extracts a 24-bit high resolution WAV file. It handles both DST and DSD streams.

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.

TinyALSA is a small library to interface with ALSA in the Linux kernel.

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

Swh-plugins-lv2 is a collection of audio plugins in LV2 format. Plugin classes include: dynamics (compressor, limiter), time (delay, chorus, flanger), ringmodulator, distortion, filters, pitchshift, oscillators, emulation (valve, tape), bit fiddling (decimator, pointer-cast), etc.

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 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.

This C++ library implements the Butterworth, RBJ, and Chebychev IIR filters. Samples are processed one by one, in real time. It can easily import coefficients generated with Python (scipy). It also avoids memory leaks by allocating memory at compile time, using templates, instead of calling malloc() or new.

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.

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.

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

libebur128 is a C library that implements the EBU R 128 standard for loudness normalisation.

This is a free software version of SGI's audiofile library. It provides a uniform programming interface for processing of audio data to and from audio files of many common formats.

Currently supported file formats include AIFF/AIFF-C, WAVE, and NeXT/Sun .snd/.au, BICS, and raw data. Supported compression formats are currently G.711 mu-law and A-law.

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

JACK is a low-latency audio server. It can connect a number of different applications to an audio device, as well as allowing them to share audio between themselves. JACK is different from other audio server efforts in that it has been designed from the ground up to be suitable for professional audio work. This means that it focuses on two key areas: synchronous execution of all clients, and low latency operation.

TTA performs lossless compression on multichannel 8,16 and 24 bits data of the Wav audio files. Being lossless means that no data- quality is lost in the compression - when uncompressed, the data will be identical to the original. The compression ratios of TTA depend on the type of music file being compressed, but the compression size will generally range between 30% - 70% of the original. TTA format supports both of ID3v1/v2 and APEv2 tags.

yabridgectl is a tool to setup and update yabridge.
