Debian Multimedia Audio plugins packages

abGate is a LV2 noise gate plugin in the LV2 format to manage noise. A noise gate is a component which attenuates an audio signal when it falls below a set threshold, so it can be applied to an audio track which has one or more periods of silence where no noise should be apparent.

A set of ambisonics plugins, mainly to be used within Ardour. Mono and stereo to B-format panning, horizontal rotator, square, hexagon and cube decoders.

AmbDec is an Ambisonics decoder for up to 36 speakers. It can be used for both horizontal and full 3-D systems of first, second and third order. The decoding matrices are fully user-configurable. AmbDec has some advanced features not found on most decoders:

• Dual frequency band operation.
• Speaker distance compensation.
• Near-field effect compensation.

All three features can be selectively enabled or disabled in the configuration.

AlsaModularSynth is a realtime modular synthesizer and effect processor. It features:

• MIDI controlled modular software synthesis.
• Realtime effect processing with capture from e.g. "Line In" or "Mic In".
• Full control of all synthesis and effect parameters via MIDI.
• Integrated LADSPA Browser with search capability.
• JACK Support.

The audiofile library allows the processing of audio data to and from audio files of many common formats (currently AIFF, AIFF-C, WAVE, NeXT/Sun, BICS, and raw data).

This package contains the sfinfo and sfconvert tools.

Autotalent is a real-time pitch correction plugin. Users can specify the notes that a singer is allowed to hit, and Autotalent makes sure that they do. Autotalent may be used for more exotic effects, like the Cher / T-Pain effect, making your voice sound like a chiptune, adding artificial vibrato, or messing with your formants. Autotalent can also be used as a harmonizer that knows how to sing in the scale with you. Or, you can use Autotalent to change the scale of a melody between major and minor or to change the musical mode.

Autotalent was designed from the ground up to process musical melodies, whether sung or played on some kind of instrument. As long as you give it a monophonic source (i.e. a melody in a single, 1-channel track), you can usually expect pretty good results. So this means that if you're in the business of processing vocal harmonies, you should apply it to each monophonic vocal part separately. If in the spirit of experimentation you're daring enough to try tuning or pitch shifting an entire chord using one instance of the plugin (again not what it's meant for), you'll hear gritty nastiness.

avw.lv2 consists in a subset of the AMS internal modules ported into LV2 plugins. It provides VCOs, LFOs, Filters and other modules controlled using Voltage Controls.

A collection of LADSPA plugins containing three anti-aliased, minBLEP-based, hard-sync-capable oscillator plugins. The oscillators are intended to be used with modular synthesis systems, such as Alsa Modular Synth.

BLOP comprises a set of LADSPA plugins that generate bandlimited sawtooth, square, variable pulse and slope-variable triangle waves, for use in LADSPA aware audio applications, principally as components of a modular synthesis network.

They are wavetable based, and are designed to produce output with harmonic content as high as possible over a wide pitch range.

Additionally, there are a few extra plugins to assist in building synthesis networks, like a analogue-type sequencer, sync-square and ADSR envelope.

The Calf plugins include all todays frequently used studio effects along with some feature-rich sound processors.

Calf Studiogear is designed to run under the most flexible plugin standard in Linux, namely LV2. So you're able to insert them in lots of plugin-capable audio software like Ardour, Rosegarden and others.

The Calf Rack offers you all Calf effects and synthesizers in an easy-to-use studio rack. Wire the effects through Jack to build your own studio environment and trigger the sound processors live or through a MIDI sequencer or tracker.

caps comprises a range of classic sound effects and a few more basic audio DSP units, signal and noise generators. The suite's aim is to provide impeccable sound quality, computational efficiency and no perceptible latency.

This package contain a command line indexer tool. Used to create index files which can later be used by applications which are useing ffms2 to speed up loading of multimedia files.

Four-band parametric equaliser. 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 has the nice property of being 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 should make this plugin a good candidate for use in systems that allow automation of plugin control ports, such as Ardour, or for stage use.

The FluidSynth-DSSI package contains FluidSynth-DSSI, a wrapper for the FluidSynth SoundFont-playing software synthesizer, allowing it to function as a DSSI plugin.

DSSI is an API for audio processing plugins, particularly useful for software synthesis plugins with user interfaces.

Fomp is an LV2 port of the MCP, VCO, FIL, and WAH plugins originally written by Fons Adriaensen.

There are 13 plugins in total: 1 auto-wah, 1 EQ, 3 chorus, 5 filters, and 3 oscillators.

The plugin implementations are identical to their LADSPA forebears, except the primary frequency port of oscillators and filters has been converted to Hz to facilitate use in any host without assuming the hidden tuning frequency of AlsaModularSynth. All other frequency ports remain as they were, using octaves for faithful Moog-like modulation.

A graphical DSSI host, based on jack-dssi-host, but capable of saving and restoring plugin configuration, as well as specifying MIDI channels and layering synths.

hexter is a software synthesizer that models the sound generation of a Yamaha DX7 synthesizer. It can easily load most DX7 patch bank files, accept patch editing commands via MIDI sys-ex messages, and recreate the sound of the DX7 with great accuracy.

LV2proc is a simple command line effect processor using LV2 plugins.

lv2proc generates an output sound file by applying a LV2 effect plugin to an input sound file.

Perhaps you don't know what a vocoder is, but I'm sure you have heard one before. Vocoders are often used to add a robotic effect to vocals in music. Happy robots use Linux and LV2!

This vocoder plugin has 2 AUDIO inputs and 1 OUTPUT. The first INPUT is the "Formant" signal which is usually someone's voice. The second INPUT is the "Carrier" signal which is some sort of continuous synth sound. The "Carrier" signal is modulated to the "Formant".

There are a number of controls ports. The first one is the "Number of bands" which is how many frequency bands to use (current maximum is 16). The rest of the controls set the level of each individual band and should have a value between 0.0 and 1.0. The lower numbered bands are lower in frequency the higher numbered bands are higher in frequency.

MCP plugins implement a set of LADSPA plugins that vastly improve the sound of AlsaModularSynth.

Currently they consist of these plugins:

NASPRO bridges is a collection of bridges to LV2 which, once installed, allow users to use plugins developed for other plugin standards in LV2 hosts.

This release contains two such bridges: a LADSPA (+ LRDF) and a DSSI one.

The LADSPA bridge supports every feature of LADSPA and LRDF except:

• run_adding() and set_run_adding_gain().

• LRDF factory presets. The DSSI bridge does not support:

• GUIs;

• MIDI programs;
• maximum number of events per run_synth() - it is 4096, should be enough in most cases;
• run_synth_adding() - as before;
• run_multiple_synths() and run_multiple_synths_adding() - no extension to do that and it may also be impossible to support those.

Recreate those squelchy acid sounds with nekobee, a simple single-oscillator synth based on the Roland TB-303.

setBfree is a MIDI-controlled, software synthesizer designed to imitate the sound and properties of the electromechanical organs and sound modification devices that brought world-wide fame to the names and products of Laurens Hammond and Don Leslie.

A monophonic synth plugin that sends the sound from two sine oscillators through two sine waveshapers in series. You can control the vibrato, tremolo, portamento, the tuning of both oscillators, the oscillator mix, and the shape amount (total and split over both shapers). There is also an ADSR envelope generator that can control the total shape amount and the amplification (with controllable sensitivity for both), an LFO for the total shape amount, and a feedback delay. The shape amount and amplification is velocity sensitive, and the "Mod Wheel" MIDI controller is bound to the total shape amount.

This is a development version, so things will probably change - don't use this plugin in a patch or song and expect later versions to work in the same way.

Man pages documenting the SLV2 API. SLV2 is a library geared towards music and audio applications which makes the use of LV2 plugins as simple as possible. LV2 is a standard for plugins and matching host applications, mainly targeted at audio processing and generation.

Los Plugins (Equalizer, Reverberator, Stereo Echo, Tremolo, Scaling Limiter, AutoPanner y DeEsser) han sido escritos principalmente para Ardour pero deberían funcionar correctamente en cualquier host LADSPA.

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.

Just like an audio effects plugin (such as a VST), a Vamp plugin is a binary module that can be loaded up by a host application and fed audio data. However, unlike an effects plugin, a Vamp plugin outputs not processed audio but some sort of symbolic information. Typical things that a Vamp plugin might calculate include the locations of moments such as note onset times, visual representations of the audio such as histograms, or curve data such as power or fundamental frequency.

Hosts using Vamp plugins include Audacity and Sonic Visualiser.

This package contains C and C++ header files for developing Vamp plugins and hosts as well as source code of example plugins and a simple host.

This plugin contains three anti-aliased oscillators, all based on the concept of using precomputed bandlimited Dirac pulses to construct the classical waveforms. They are both memory and CPU efficient. The first one produces a flat spectrum (impulses) and the second generates a sawtooth waveform. The third one (new in 0.3.0), provides a variable width rectangular waveform.

VLevel keeps your music from making you jump out of your seat, and it keeps you from having to fiddle with the volume constantly. It's different from other dynamic compressors because it looks ahead. You can think of VLevel as someone who knows your music by heart, and turns the volume up during quiet passages, but smoothly turns it back down when he knows a loud part is coming. It's great for making CDs to listen to in your car, or to play background music on your computer.

VLevel is currently a LADSPA plugin, a JACK plugin and a command-line filter. You can use it with many Linux audio programs including XMMS, GStreamer, GLAME, GDAM, and others, and you can use it in shell scripts to level your music before burning a CD.

The commandline filter is also useful for levelling podcasts before (encoding and) publishing.

VocProc is a LV2 plugin for pitch shifting (with or without formant correction), vocoding, automatic pitch correction and harmonizing of singing voice.

This package contains the vocproc LV2 plugin.

This LADSPA plugin is the combination of a 'wah' pedal and a simple envelope follower.

Controls are:

• Freq: the resonance frequency of wah filter. This would normally be controlled using a midi pedal.
• Mix: crossfades between dry and wet signal, the first is the original input signal and the latter is the pure output of the resonant filter amplified by 18 dB.

The three remaining parameters control the envelope follower. This produces a control signal that is added to the 'Freq' setting.

• Drive: input gain to the envelope follower (so this gain is not in the signal path).
• Decay: controls the decay time of the envelope.
• Range: controls how much the envelope is allowed to modify the basic frequency.

Disposable Soft Synth Interface (DSSI). A brief list of features:

• 4 oscillators, 2 filters, 3 LFOs, and 5 envelope generators per voice.

Xsynth-DSSI was written by Sean Bolton, and was based on Steve Brooke's Xsynth code, but has since acquired polyphonic operation, band-limited oscillators, a better filter mode, and velocity-sensitive envelopes.

DSSI is an API for audio processing plugins, particularly useful for software synthesis plugins with user interfaces.

Plugins for high quality audio processing.

The purpose of these plugins is to provide high quality DSP without using an excessive amount of CPU.

AT1 is an 'autotuner', normally used to correct the pitch of a voice singing (slightly) out of tune. Compared to 'Autotalent' it provides an improved pitch estimation algorithm, and much cleaner resampling.

AT1 does not include formant correction, so it should be used to correct small errors only and not to really transpose a song. The 'expected' pitch can be controlled by Midi (via Jack only), or be a fixed set of notes. AT1 can probably be used on some instruments as well, but is primarily designed to cover the vocal range. It's also usable as a quick and dirty guitar tuner.

The zyn project main goal is to extract synth engines from ZynAddSubFX and pack them in LV2 plugin format. Resulting plugins are heavily based on work made by Nasca Octavian Paul. If you like the amazing sounds these plugins generate you should thank Paul for this.

A real-time software synthesizer for Linux and Windows with many features, including polyphony, multi-timbral and microtonal capabilities. It includes randomness of some parameters, which makes warm sounds, like analogue synthesizers. It has system/insertion effects too, and much more.

This package provides a dssi plugin of zynaddsubfx.

This package includes the csound reference manual.

REV1 is a reworked version of the reverb originally developed for Aeolus. Its character is more 'hall' than 'plate', but it can be used on a wide variety of instruments or voices. It is not a spatialiser - the early reflections are different for the L and R inputs, but do not correspond to any real room. They have been tuned to match left and right sources to some extent.

In Stereo mode a dry/wet mix control is provided, so it can be used either as an insert or in send/return mode. For mono just connect one of the two channels.

In Ambisonic mode (selected by the -B command line option) the only option is the send/return mode.

Carla is an audio plugin host, with support for many audio drivers and plugin formats. It has some nice features like automation of parameters via MIDI CC (and send output back as MIDI too) and full OSC control.

Carla currently supports LADSPA (including LRDF), DSSI, LV2, VST2/3 and AU plugin formats, plus GIG, SF2 and SFZ file support. It uses JACK as the default and preferred audio driver but also supports native drivers like ALSA, DirectSound or CoreAudio.

Ingen (formerly om) is a realtime modular synthesizer and effects processor using the JACK audio server and LADSPA or DSSI plugins. Its engine runs as an independent process controlled via the Open Sound Control (OSC) protocol, meaning many clients can control the engine simultaneously - even across a network.

Virtual Studio Technology (VST) is an audio plugin software interface that integrates software synthesizer and effects in digital audio workstations. VST and similar technologies use digital signal processing to simulate traditional recording studio hardware in software.

VST is the de-facto industry standard for audio plugins and plugin hosts.

Camomile is a meta-plugin, that allows to load Pd-patches as VST/VST3/LV2 plugin into your favourite Digital Audio Workstation.
