This package provides a stereo reverb LADSPA plugin based on the well-known greverb.

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.

lv2lint is an LV2 lint-like tool that checks whether a given plugin and its UI(s) match up with the provided metadata and adhere to well-known best practices.

This package provides an encoder for the LDAC high-resolution Bluetooth audio streaming codec for streaming at up to 990 kbps at 24 bit/96 kHz.

shntool is a multi-purpose WAVE data processing and reporting utility. File formats are abstracted from its core, so it can process any file that contains WAVE data, compressed or not---provided there exists a format module to handle that particular file type. It can also generate CUE files, and use them split WAVE data into multiple files.

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.

Carla is a modular audio plugin host, with features like transport control, automation of parameters via MIDI CC and remote control over OSC. Carla currently supports LADSPA (including LRDF), DSSI, LV2, VST2, and VST3 plugin formats, plus SF2 and SFZ file support. It uses JACK as the default and preferred audio driver but also supports native drivers like ALSA.

Omins-lv2 is a small collection of LV2 audio plugins for modular synthesis.

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.

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

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 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.

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 contains the resample and windowfilter command line utilities. The resample command allows changing the sampling rate of a sound file, while the windowfilter command allows designing Finite Impulse Response (FIR) filters using the so-called window method.

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.

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

This package provides tools for managing JACK connections and testing or configuring the JACK session. Tools include jack_lsp, jack_connect, and jack_transport.

Vamp is an audio processing plugin system for plugins that extract descriptive information from audio data — typically referred to as audio analysis plugins or audio feature extraction plugins.

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

The Bauer stereophonic-to-binaural DSP (bs2b) library and plugins is designed to improve headphone listening of stereo audio records. Recommended for headphone prolonged listening to disable superstereo fatigue without essential distortions. This package contains a LADSPA plugin for use with applications that support them (e.g. PulseAudio).

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

An LV2 port of the mda Piano VSTi.

alsa-midi-latency-test measures the roundtrip time of a MIDI message in the alsa subsystem of the Linux kernel using a high precision timer. It calculates the worst case roundtrip time of all sent MIDI messages and displays a histogram of the roundtrip time jitter.

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.
