Audacity - многоплатформенный редактор звуковых файлов, распространяемый с открытым исходным кодом. С помощью Audacity можно записывать и редактировать звуки, применять к ним различные эффекты, проигрывать их, импортировать и экспортировать в WAV, AIFF, Ogg Vorbis, MP3 и др. форматы. Программа имеет встроенный редактор амплитуды, настраиваемый режим отображения спектрограммы и средства частотного анализа звуковых дорожек. Встроенные эффекты включают усиление баса, WahWah, удаление шума, вырезание тишины, изменения скорости и высоты тона, темпа записи, плавное затухание, нарастание, повтор, реверс и многое другое. Audacity можно использовать для оцифровки аналоговых записей (кассет, грампластинок), физического редактирования нескольких файлов (вырезание, склейка, сведение).

Основные возможности:

Запись
• Audacity может записывать звук извне с микрофона, встроенного в ОС микшера или канала Line In, к которому можно подключить кассетный магнитофон, проигрыватель грампластинок или минидисков. При использовании некоторых звуковых карт можно записывать и потоковый звук.
• Запись с микрофона, линейного входа или других источников.
• Запись с одновременным прослушиванием имеющихся дорожек.
• Запись до 16 каналов одновременно (необходима многоканальная звуковая карта).
• Индикаторы громкости до, во время и после записи.

Импорт и экспорт звуковых данных
• Вы можете импортировать звуковые файлы в проект Audacity, изменить их, объединить с другими файлами или новыми записями, экспортировать результат в файлы нескольких форматов.
• Импорт и экспорт файлов в форматах WAV, AIFF, AU, и Ogg Vorbis.
• Импорт звука в MPEG (включая файлы MP2 и MP3) при помощи libmad.
• Экспорт в MP3 при помощи кодировщика LAME, устанавливаемого отдельно.
• Создание файлов WAV и AIFF, которые можно записать на звуковой компакт-диск.
• Импорт и экспорт файлов всех форматов, поддерживаемых библиотекой libsndfile.
• Открытие raw-файлов (файлов без заголовков) при помощи команды «Импортировать raw-файл».

Редактирование
• Базовые операции вырезания, копирования, вставки и удаления.
• Неограниченная история изменения, по которой можно отменить и повторить действие.
• Очень быстрое изменение больших файлов.
• Изменение и сведение неограниченного числа дорожек.
• Использование «карандаша» для редактирования отдельных точек сэмплов.
• Плавное изменение громкости при помощи инструмента редактирования огибающей.

Эффекты
• Смена высоты тона без изменения темпа и наоборот.
• Удаление статического шума, гула, шипения и других постоянных шумовых дефектов записи.
• Изменение частотных характеристик при помощи эквалайзера, FFT-фильтра и эффекта усиления баса.
• Подстройка громкости при помощи компрессора, эффекта усиления и или нормализации.
• Другие встроенные эффекты:
• Эхо
• Фейзер
• Wahwah
• Разворот

Качество звука
• Запись и редактирование 16/24/32-битных (32бит — с плавающей точкой) звуковых данных.
• Частота дискретизации до 96 кГц.
• Преобразования частот дискретизации и битовой глубины производятся с использованием качественных алгоритмов ресэмплинга и дитеринга.
• Сведение дорожек с разными качественными характеристиками с автоматическим преобразованием до характеристик проекта в режиме реального времени.

Модули (Plug-Ins)
• Всегда можно добавить новые LADSPA-модули.
• Audacity включает несколько LADSPA-модулей Стива Хэрриса (Steve Harris).
• Использование VST-модулей под Windows и Mac при помощи скачиваемого отдельно модуля VST Enabler.
• Создание своих эффектов на простом встроенном языке Nyquist.

Анализ
• Спектрографический режим отображения дорожек.
• Команда «Нарисовать график спектра» для детального анализа частотных характеристик.

Свобода использования и многоплатформенность
• Программа распространяется на условиях GNU General Public License (GPL).
• Работает в Mac OS X, Windows, GNU/Linux и некоторых Unix-системах.

Audacity 2.0

Изменения:

Changes between 1.3.14 and 2.0.0

Bug fixes

Interface

• Fixed playback speed and synchronization problems when dragging clips or tracks between tracks having different sample rates.
• (Windows) Removed a crash risk where shortcuts could be used to record or import in one project while importing or exporting in another.

Imports and Exports

• Fixed crashes when changing the sample format of read-directly WAV or AIFF files using the Track Drop-Down Menu.
• Fixed a crash importing MP3 files that had duplicate metadata tags (this is a bug in current libsndfile which has been patched in Audacity; MP3 files mislabeled as WAV which have duplicate tags will still crash Audacity on Linux if Audacity has been compiled against an affected version of system libsndfile).
• Fixed an issue where excessively high or corrupted sample values in the audio could corrupt exports from the start of the problem for the rest of the file, and could corrupt the rest of the project.
• (Linux) Fixed Audacity could not be compiled against FFmpeg 0.7.x and 0.8.x.

Effects and Analysis

• Fixed crash on launch when using "Ambisonic Decoders (PC)" VST plug-ins and other plug-ins that enable additional floating point exceptions.
• Fixed Plot Spectrum background could be transparent on some machines.
• Bug fixes for Click Track, High Pass, Low Pass and Vocal Remover.
• Chirp, Tone and Silence generators now remember their settings.

Other miscellaneous bug fixes

Changes and Improvements

• New Interface preference to show the track name in the display (this is off by default).
• Longer default Playback preference for effects preview and preview before cut.
• Restored use of Page Up and Page Down to scroll horizontally.

Summary of bug fixes and new features between 1.2.6 and 2.0.0

Bug Fixes

• Labels now accept lower case "z".
• (Windows Vista/7) Pressing Stop after recording could cause a crash.
• (Mac OS X) Fixed shortcut keys activating when typing in file open or save windows.
• (Mac OS X) Audacity 2.0.0 fully supports Unicode, which fixes an issue where Audacity could not work with folders having non-English characters in their name.
• (Linux) Playing existing tracks while recording in mono could cause recordings to be distorted or low-pitched.

New features

These are some of the dozens of new features in 2.0.0.

• Many effects significantly improved, especially Equalization, Noise Removal and Normalize. Vocal Remover now included plus GVerb on Windows and Mac. VAMP analysis plug-ins now supported.
• Improved label tracks with Sync-Lock Tracks feature in the Tracks Menu.
• Multiple clips per track. Tracks and selections can be fully manipulated using the keyboard. Many more keyboard shortcuts.
• New Device Toolbar to manage inputs and outputs. Timer Record feature. New Mixer Board view with per-track VU meters.
• Automatic Crash Recovery in the event of abnormal program termination.
• Fast "On-Demand" import of WAV/AIFF files if read directly from source.
• FLAC now fully supported. Added support for optional FFmpeg library for import/export of AC3/M4A/WMA and import of audio from video files.

Audacity 2.0.1

Изменения:

Changes since version 2.0.0:

Bug fixes for:

• Interface:
  • Selection Toolbar: a value for the previous whole second displayed if the value was close to a whole second.
  • Finding zero crossings could cause the selection to expand into white space at either side of the clip.
  • Clips did not drag to another track if mouse was over a selection.
  • Mixer Board: Rendering four tracks resulted in a redundant Track Strip followed by a crash.
• Imports, Exports and Files:
  • Exporting to WAV or AIFF led to a "Libsndfile says" error or corrupted output due to order of metadata in imported files.
  • (Mac) Fixed crashes importing MP3 files on PPC machines.
  • (Linux Ubuntu) .Aup files could not be associated with Audacity (they opened in the web browser instead).
• Effects and Analysis:
  • Normalize: Fixed issues where normalization could be to wrong value if applied with DC offset correction, or if applied to "read-directly" WAV and AIFF files before On-Demand completed.
  • Sliding Time Scale: fixed an audible discontinuity at the beginning of the processed selection; fixed a serious quality problem on Linux 64-bit.
• Other miscellaneous bug fixes, including fix to prevent zooming with mouse wheel or ball scrolling the content off-screen.

Changes and Improvements:

• Shortcuts can now be added in Keyboard Preferences to items in the Generate, Effect or Analyze menus, including user-added plug-ins.
• Nyquist Effect plug-ins can now be added to Chains.
• New "Paulstretch" effect for extreme slowdown without pitch change.
• New "Sample Data Export" Analyze effect for exporting a file containing amplitude values for each sample in the selection.
• New Preference (off by default) to import files On-Demand (without seek ability) when using the optional FFmpeg library.
• New Preference (off by default) to retain labels when deleting a selection that snaps to the label without extending past it.
• (Windows installer) New option to reset Preferences on next launch.
• (Mac) Audacity now has excellent compatibility with the VoiceOver screen reader. For details, please see: http://manual.audacityteam.org/help/...ility.html#mac.
• CleanSpeech Mode (no longer supported) will not now be enabled even if it was enabled by an earlier version of Audacity.
• Added Serbian (Latin and Cyrillic) translations.

Audacity 2.0.2

Изменения:

Changes since version 2.0.1:

Bug fixes for:

• Interface:
  • "Retain labels" Interface Preference did not retain labels for a region that snapped exactly to both label edges.
  • Projects did not save the track selected state.
  • (OS X, Linux) Timer Record: Interlinking of the Start, End and Duration controls was broken.
  • (Windows) JAWS screen-reader did not read the "Draw curves" and "Graphic EQ" radio buttons in Equalization correctly.
• Envelopes and Clips:
  • Exporting (or any render operation) on a track containing split lines could create clicks at the split lines.
  • Dragging a clip into another track caused a crash if Sync-Lock Tracks was enabled and there was also a label track.
• Effects and Analysis:
  • Normalize could crash if the track name contained "%".

Changes and Improvements:

• Duration controls when generating at a point now default to hh:mm:ss + milliseconds format. Selection Toolbar also defaults to that format on first installation or resetting preferences.
• Toolbars visual improvements:
  • "Snap To" in Selection Toolbar now has an explanatory tooltip.
  • Device Toolbar tooltips now display the selected device.
  • Increased default width of Device Toolbar and Meter Toolbar.
• Improvements and some bug fixes to Nyquist effects, including:
  • Delay (new option to prevent duration change)
  • Sample Data Export (new "L-R on Same Line" layout option)
  • Risset Drum (new "Amplitude" slider).
• Importing a labels file writes the file name to the name of the Label Track, and exporting a labels file offers the name of the last Label Track in the project.
• Removed the "Audio cache" option from Directories Preferences due to frequent crash reports. All data operations will now be written to disk and not to RAM.
• Removed the FFmpeg "On-Demand" option from Libraries Preferences (this fixes Audacity not building if configured --without-ffmpeg).
• Compilation: Progress on making the Modules feature mainstream. Modules can now be individually enabled and disabled in Preferences.

Audacity 2.0.4

Изменения:

Bug fixes

• Keyboard Preferences: Shortcuts for Generators, Effects and Analyzers were not exported. All imported shortcut changes were discarded.
• Equalization curves were corrupted in Graphic EQ mode after switching to/from Draw Curves or after running the effect then reopening it.
• Change Pitch displayed corrupted values when reducing pitch or editing "from" Frequency. Detection was very inaccurate at high sample rates.
• Bass Boost no longer clips if the track contains 32-bit audio.
• Auto Duck was excessively slow on older machines.
• (Windows) Exported MP3 comments tags were not seen by Windows programs.
• (Windows and OS X) Audacity crashed if you used system quit before file import was complete.
• (Linux) Equalization crashed Audacity if the XML file was corrupted.
• (Linux) When configuring effect parameters in "Edit Chains", "Preview" (not intended to be functional) caused a crash.
• (Linux) LICENSE.txt and README.txt were wrongly installed in /usr/local/share/doc instead of /usr/local/share/doc/audacity/ .
• Accessibility: ENTER did not toggle selectedness of a label track unless a label was selected.
• Numerous other interface fixes.

Changes and Improvements

• New "Reverb" effect to replace GVerb, based on the original "Freeverb".
• New View > Go to Selection Start and Go to Selection End commands.
• New Tracks > Align End to End command to append existing tracks to each other.
• Change Tempo now supports fractional BPM.
• Plot Spectrum now supports FFT sizes up to 65536.
• WAV files now support "Album Title", "Track Number" and "Genre" LIST INFO tags and also support ID3 tags.
• Handle a bug in older iPods or some OS X applications that cause them to refuse AIFF files whose metadata contains an uneven number of characters,
• (Windows) Added support for "Windows WDM-KS" host which can provide very low latencies if you reduce "Audio to Buffer" in Recording Preferences.
• (Windows Vista and later) You can now record computer playback by choosing the new "Windows WASAPI" host in Device Toolbar then a "loopback" input.
• (Windows and Mac OS X): VST scanning dialog now replaced with a dialog for choosing which VST effects to load.
• (Linux) CTRL + ALT can now be used to smooth samples in Draw Tool.
• Modules Preferences replaced with a dialog on launch of Audacity enabling you to choose which modules to load.

Audacity 2.0.5

Изменения:

Bug fixes

• Shaped dither was corrupted and too loud on all stereo exports except FLAC.
• Keyboard Preferences: some Edit and Align commands for different sub-menus showed the same name.
• Recordings stopped with "Stop and Set Cursor" shortcut could not be undone.
• In locales that use comma for decimal separator:
  • Text boxes with slider in Nyquist effects only produced whole numbers when using comma to enter a fractional number. Text boxes without slider still have this problem.
  • Built-in generators produced silence after running a Nyquist effect.
• (Windows) When first changing to Windows WASAPI host, the input volume slider in Mixer Toolbar was enabled when it should have been permanently disabled.
• (Windows) On some machines, launching Audacity then recording from the current Device Toolbar input would not record until the input was reselected.
• (OS X) Frequent crashes occurred on importing audio files on some machines.
• (OS X) Files did not open using Finder "Open with", double-clicking the file or dragging the file to the Audacity icon.
• (Linux 64-bit) Fixed a crash when using Equalization.
• (Linux) It was not possible to open an effect or other dialog then navigate through the dialog using TAB.
• (Linux) The Play shortcut did not play a read-directly WAV, AIFF or FLAC import if the warning for importing uncompressed files appeared.

Changes and Improvements

• Tracks Menu:
• The separate commands that aligned track start or end with the cursor or with selection start are combined into "Cursor/Selection Start" commands.
• "Align and Move Cursor" renamed to "Move Selection when Aligning".
• Label Tracks:
  • Labels Editor now allows empty labels to be saved on closing the editor.
  • TAB and SHIFT+TAB when the label track has focus now always move forwards or backwards respectively to the nearest label.
• (Windows) On a very few machines, the Windows WDM-KS low latency audio host introduced in Audacity 2.0.4 caused Audacity to hang or the computer to crash. WDM-KS has been removed from 2.0.5 until it can be safely enabled.
• (Windows and OS X) Screen reader improvements for Install VST Effects dialog.
• (OS X) Audio Unit plug-ins detected by Audacity on launch are now not loaded until chosen from the Effect menu. This should speed up launch and avoid crashes at launch due to misbehaving Audio Units.
• (Linux) Update to PortAudio r1910 fixes memory and other bugs under ALSA.
• (Linux) Applied fix for wxGTK 2.8.12 bug which resulted in loss of Audacity's menu bar (or visual corruption under Unity) on Debian-based systems.
