TAP (Tom's Audio Processing) plugins is a collection of audio effect plugins originally released as LADSPA plugins. This package offers an LV2 version ported by moddevices.

LSP (Linux Studio Plugins) is a collection of audio plugins available as LADSPA/LV2 plugins and as standalone JACK applications.

The Sherlock plugin bundle contains LV2 plugins for visualizing LV2 atom, MIDI and OSC events. They can be used for monitoring and debugging of event signal flows inside plugin graphs.

amsynth is an easy-to-use software synthesizer with a classic subtractive synthesizer topology. Its features include: dual oscillators (sine, saw, square, noise) with hard sync; 12 and 24 dB/oct resonant filters (low-pass, high-pass, band-pass, notch); mono, poly, legato keyboard modes; dual ADSR envelope generators for filter and amplitude; LFO which can modulate the oscillators, filter, and amplitude; distortion and reverb effects.

This application displays an icon in the system tray (also known as notification area) of your desktop, which shows the status of the JACK audio server and when you click on it, a menu pops up, which lets you quickly select from the JACK configuration presets you created with QjackCtl. When you select a preset, its JACK engine and driver configuration settings are loaded via DBus into JACK and then the server is restarted. This allows you to switch between different audio setups with just two mouse clicks.

Padthv1 is an old-school polyphonic additive synthesizer with stereo effects. Padthv1 is based on the PADsynth algorithm by Paul Nasca, as a special variant of additive synthesis.

Mutagen is a Python module to handle audio metadata. It supports ASF, FLAC, M4A, Monkey’s Audio, MP3, Musepack, Ogg FLAC, Ogg Speex, Ogg Theora, Ogg Vorbis, True Audio, WavPack and OptimFROG audio files. All versions of ID3v2 are supported, and all standard ID3v2.4 frames are parsed. It can read Xing headers to accurately calculate the bitrate and length of MP3s. ID3 and APEv2 tags can be edited regardless of audio format. It can also manipulate Ogg streams on an individual packet/page level.

Samplv1 is an old-school polyphonic sampler synthesizer with stereo effects.

This package provides the LV2 plugin "GxVoodooFuzz", a simulation modelled after the Voodoo Lab SuperFuzz pedal. It's basically a Bosstone circuit, followed by the tone control of the FoxToneMachine in parallel with a DarkBooster, followed by a volume control.

Zrythm is a digital audio workstation designed to be featureful and easy to use. It offers unlimited automation options, LV2 plugin support, JACK support and chord assistance.

Sorcer is a wavetable LV2 plugin synthesizer, targeted at the electronic or dubstep genre.

This set of LV2 plugins is a port of the internal modules found in Alsa Modular Synth. These plugins are used to create modular synthesizers and contain: VCO, VCF, VCA, LFO, slew limiter, envelopes, sample and hold, etc.

Synthesis ToolKit in C++ (STK) is a set of audio signal processing and algorithmic synthesis classes written in C++.

This package also provides its demo project, examples, ElectricGuitar, RagaMatic and Effects.

Fabla is an LV2 drum sampler plugin instrument. It is ideal for loading up your favorite sampled sounds and bashing away on a MIDI controller.

LINGOT is a musical instrument tuner. It's accurate, easy to use, and highly configurable. Originally conceived to tune electric guitars, it can now be used to tune other instruments.

It looks like an analogue tuner, with a gauge indicating the relative shift to a certain note, determined automatically as the closest note to the estimated frequency.

The MusicBrainz::DiscID module is a Perl interface to the MusicBrainz libdiscid library, allowing you to manipulate digital audio compact disc (CDDA) identifiers.

This package provides the LV2 plugin "GxSlowGear", a slow gear audio effect to produce volume swells.

The 6581 SID chip is the sound chip used in the Commodore 64 computer. reMID is a MIDI implementation of the 6581 SID chip using the reSID library to provide a virtual SID-based synthesizer, controllable in real-time via MIDI. It includes support for scripted instruments that allow complex sonic control of the chip.

Flacon extracts individual tracks from one big audio file containing an entire CD of music and saves them as separate audio files. To do this, it uses information from the appropriate CUE file. Also, Flacon makes it possible to conveniently revise or specify tags both for all tracks at once or for each tag separately.

Qtractor is an Audio/MIDI multi-track sequencer application. It uses JACK for audio and ALSA sequencer for MIDI as multimedia infrastructures and follows a traditional multi-track tape recorder control paradigm.

Pure Data (aka Pd) is a visual programming language. Pd enables musicians, visual artists, performers, researchers, and developers to create software graphically, without writing lines of code. Pd is used to process and generate sound, video, 2D/3D graphics, and interface sensors, input devices, and MIDI. Pd can easily work over local and remote networks to integrate wearable technology, motor systems, lighting rigs, and other equipment. Pd is suitable for learning basic multimedia processing and visual programming methods as well as for realizing complex systems for large-scale projects.

This package provides the LV2 plugin "GxVBassPreAmp", a pre-amplifier simulation modelled after the 1984 Vox Venue Bass 100 Pre Amp Section.

Midicsv reads a standard MIDI file and decodes it into a comma-separated value file (CSV), which preserves all the information in the MIDI file. The ASCII CSV file may be loaded into a spreadsheet or database application, or processed by a program to transform the MIDI data (for example, to key transpose a composition or extract a track from a multi-track sequence). A CSV file in the format created by midicsv may be converted back into a standard MIDI file with the csvmidi program.

DUMB is a tracker library with support for IT, XM, S3M and MOD files. It targets maximum accuracy to the original formats, with low-pass resonant filters for the IT files, accurate timing and pitching, and three resampling quality settings (aliasing, linear interpolation and cubic interpolation).
