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.

CHOW Tape is an analog tape machine physical model, originally based on the Sony TC-260. The current version can be used to emulate a wide variety of reel-to-reel tape machines.

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

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.

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.

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

Autotalent is a LADSPA plugin for real-time pitch-correction. Among its controls are allowable notes, strength of correction, LFO for vibrato and formant warp.

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.

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.

liblo is a lightweight library that provides an easy to use implementation of the Open Sound Control (OSC) protocol.

This project is a rebirth of a direct integration between Bluez and ALSA. Since Bluez >= 5, the built-in integration has been removed in favor of 3rd party audio applications. From now on, Bluez acts as a middleware between an audio application, which implements Bluetooth audio profile, and a Bluetooth audio device. BlueALSA registers all known Bluetooth audio profiles in Bluez, so in theory every Bluetooth device (with audio capabilities) can be connected. In order to access the audio stream, one has to connect to the ALSA PCM device called bluealsa. The device is based on the ALSA software PCM plugin.

libmt32emu is a C/C++ library which approximately emulates the Roland MT-32, CM-32L and LAPC-I synthesizer modules. It is part of the Munt project.

An LV2 port of the mda EPiano VSTi.

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.

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

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.

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

Augeas is a library and command line tool for programmatically editing configuration files in a controlled manner. Augeas exposes a tree of all configuration settings and a simple local API for manipulating the tree. Augeas then modifies underlying configuration files according to the changes that have been made to the tree; it does as little modeling of configurations as possible, and focuses exclusivley on transforming the tree-oriented syntax of its public API to the myriad syntaxes of individual configuration files.

Pure Python bindings for Augeas.

oauth2l (pronounced ``oauth tool'') is a simple command-line tool for working with Google OAuth 2.0 written in Go. Its primary use is to fetch and print OAuth 2.0 access tokens, which can be used with other command-line tools and scripts.

The Yubico PAM module provides an easy way to integrate the YubiKey into your existing user authentication infrastructure.

This package provides a library to generate HOTPs as specified in RFC 4226 and TOTPs as specified in RFC 6238.

The OATH Toolkit provides various components for building OTP authentication systems:

• oathtool, a command-line tool for generating & validating OTPs.

• liboath, a C library for OATH handling.

• pskctool, a command-line tool for manipulating secret key files in the PSKC format described in RFC6030.

• libpskc, a shared and static C library for PSKC handling.

• pam_oath, a PAM module for pluggable login authentication.

Supported technologies include the event-based HOTP algorithm (RFC4226), the time-based TOTP algorithm (RFC6238), and PSKC (RFC6030) to manage secret key data.

Pamtester is a tiny utility program to test the pluggable authentication modules (PAM) facility, specifically designed to help PAM module authors to intensively test their own modules.
