Openstudio Openstudiopro-timestretching packages

This is a program for stretching the audio. It is suitable only for extreme sound stretching of the audio (like 50x) and for applying special effects by "spectral smoothing" the sounds. It can transform any sound/music to a texture.

It produces high quality extreme sound stretching. While most sound stretching software sounds bad when trying to stretch the sounds a lot, this one is optimized for extreme sound stretching.

The stretch amount is unlimited. You can play the stretched sound in real-time (including the possibility to "freeze" the sound) or you can render the whole sound or a part of it to audio files.

It has many post-processing effects, like: filters, pitch/frequency shifters Support for WAV, OGG VORBIS files and MP3 files.

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

This package contains a command-line utility that can be used to exploit Rubber Band's capabilities.

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

This package contains a LADSPA plugin that can change the pitch of a sound in real-time.

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

This package contains the following Vamp plugins:

• increments (Output Increments): Output time increment for each input step

• aggregate_increments (Accumulated Output Increments): Accumulated output time increments

• divergence (Divergence from Linear): Difference between actual output time and the output time for a theoretical linear stretch

• phaseresetdf (Phase Reset Detection Function): Curve whose peaks are used to identify transients for phase reset points

• smoothedphaseresetdf (Smoothed Phase Reset Detection Function): Phase reset curve smoothed for peak picking

• phaseresetpoints (Phase Reset Points): Points estimated as transients at which phase reset occurs

• timesyncpoints (Time Sync Points): Salient points which stretcher aims to place with strictly correct timing

StretchPlayer will play back an audio file and allow you to time stretch (without affecting pitch) and/or pitch shift (without affecting the time) the audio, even while you are listening to it.

Warning: this package contains the development version (potentially unstable) released for testing purpose only.

Ardour is a multichannel hard disk recorder (HDR) and digital audio workstation (DAW). It can be used to control, record, edit and run complex audio setups.

Ardour supports pro-audio interfaces through the ALSA project, which provides high quality, well designed device drivers and API's for audio I/O under Linux. Any interface supported by ALSA can be used with Ardour. This includes the all-digital 26 channel RME Hammerfall, the Midiman Delta 1010 and many others.

Ardour has support for 24 bit samples using floating point internally, non-linear editing with unlimited undo, a user-configurable mixer, MTC master/slave capabilities, MIDI hardware control surface compatibility.

It supports MIDI Machine Control, and so can be controlled from any MMC controller and many modern digital mixers.

Ardour contains a powerful multitrack audio editor/arranger that is completely non-destructive and capable of all standard non-linear editing operations (insert, replace, delete, move, trim, select, cut/copy/paste). The editor has unlimited undo/redo capabilities and can save independent "versions" of a track or an entire piece

Ardour's editor supports the community-developed LADSPA plugin standard. Arbitrary chains of plugins can be attached to any portion of a track. Every mixer strip can have any number of inputs and outputs, not just mono, stereo or 5.1. An N-way panner is included, with support for various panning models. Pre- and post-fader sends exist, each with their own gain and pan controls. Every mixer strip acts as its own bus, and thus the bus count in Ardour is unlimited. You can submix any number of strips into another strip.

Ardour's channel capacity is limited only by the number on your audio interface and the ability of your disk subsystem to stream the data back and forth.

JACK (the JACK Audio Connection Kit) is used for all audio I/O, permitting data to be exchanged in perfect samplesync with other applications and/or hardware audio interfaces.

Ardour is sample rate and size neutral - any hardware formats from 8 to 32 bits, and rates from 8kHz to 192kHz. Internal processing in 32/64 bit IEEE floating point format.

Qtractor is a MIDI/Audio multi-track sequencer application written in C++ around the Qt4 toolkit using Qt Designer.

The Jack Audio Connection Kit (JACK) for audio, and the Advanced Linux Sound Architecture (ALSA) for MIDI, are the main infrastructures to evolve as a fairly-featured Linux Desktop Audio Workstation GUI, especially dedicated to the personal home-studio.

Rosegarden is a Qt application which provides a mixed Audio/MIDI sequencer (for playback and recording), a multi-track editor, music editing using both piano-roll and score notation, MIDI file IO, lilypond and Csound files export, etc.
