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 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 はマルチチャンネルのハードディスクレコーダ (HDR) および ディジタルオーディオワークステーション (DAW) です。複雑なオーディオ環境の 制御、記録、編集、起動に利用できます。

Ardour は、Linux においてオーディオ I/O 用の高品質かつ良質な設計の デバイスドライバや API を提供している ALSA プロジェクトによりプロ品質の インターフェースをサポートします。Ardour は、ALSA によりサポートされるあらゆる インターフェースを利用できます。これにはフルディジタルの 26 チャンネル RME hammerfall、Midiman Delta 1010 を始めとするさまざまなインターフェースが 含まれます。

Ardour は、内部的に浮動小数点を利用した 24 ビットのサンプリング、 無制限のやり直しが可能な非線形編集、ユーザが設定可能なミキサ、MTC マスター/スレーブ機能、MIDI ハードウェア制御インターフェース互換機能を サポートします。

MIDI Machine Control (MMC) をサポートするので、MMC コントローラなどの 最新のディジタルミキサから制御可能です。

Ardour にはパワフルなマルチトラックなオーディオエディタ/アレンジのツールが 含まれます。このツールが元のデータを破壊することは一切なく、また 標準的なすべての非線形編集操作 (挿入、置換、削除、移動、トリム、選択、 カット/コピー/ペースト) を実行できます。エディタには無制限のやり直し/繰り返し 機能があり、トラック単位または音楽全体で別々の "バージョン" を保存できます。

Ardour のエディタはコミュニティにより開発された LADSPA プラグイン標準を サポートします。任意のプラグインのチェインをトラックの任意の場所に 追加できます。各ミキサストリップは、モノラル、ステレオ、5.1 ch だけでなく 無制限の入力チャンネルと出力チャンネルを利用することができます。 N-ウェイパンニングツールが含まれ、各種パンニングモデルをサポートします。 プリフェーダ/ポストフェーダのセンドが存在し、それぞれは独自のゲインと パン制御が可能です。各ミキサストリップは独自のバスとして振る舞うので、 Ardour におけるバスの数は無制限です。他のストリップに任意の数のストリップを サブミックスできます。

Ardour のチャンネル機能はマシンのオーディオインターフェースの数と ストリームデータをやりとりするディスクの能力によってのみ制限されます。

JACK (JACK Audio Connectio Kit) をすべてのオーディオ I/O に利用しており、 完全同期のサンプリングで他のアプリケーションや ハードウェアオーディオインターフェースとデータを交換できます。

Ardour にサンプリングレートやサイズによる制限はなく、8 ビットから 32 ビットまで、そして 8kHz から 192kHz までのあらゆるハードウェアフォーマットを サポートします。内部処理は 32/64 ビットの IEEE 浮動小数点フォーマットで 行われます。

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.
