Audacity X 2.0.0 - Changelog

What's new in Audacity X 2.0.0:

March 14th, 2012

Changes since version 1.3.14 Beta:

Bug fixes for:
* 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.


· 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: There are dozens of new features in 2.0.0, including:
· 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.

What's new in Audacity X 1.3.14 Beta:

February 17th, 2012

Bug fixes:
· Fixes for data loss when encountering corrupted project files. Steps taken to prevent writing of overlong audio data block files.
· Excessive delay occurred when typing into labels in long projects.
· MP2 files could not be imported natively. File types requiring FFmpeg library imported as noise if FFmpeg was unavailable.
· Crashes fixed when dragging tracks. Crash fixed when resetting Toolbars when an audio stream was present.
· Plot Spectrum didn't preserve signal level if multiple tracks were analyzed.

Changes and Improvements:
· Normalize now preserves left-right balance in stereo tracks by default with an option to normalize stereo channels independently.
· Spectrograms now allow window sizes up to 32768 and frequencies up to half the sample rate (the maximum possible).
· Mix and Render now preserves clip length by not rendering white space before the start of audio, and preserves audio before time zero.
· CleanSpeech Mode has been removed from Preferences but can be run or disabled in 1.3.14 by changing Preferences in a previous Audacity version.
· (OS X) Added support for AudioUnit MusicEffects (but no MIDI support).

What's new in Audacity X 1.3.13 Beta:

April 12th, 2011

Bug fixes for:
Interface:
· Cutting or copying from a track at a given sample rate into a track at another rate resulted in speed-changed audio.
· Generating inside a clip could modify the clip length or create spurious clips.
· Recorded stereo tracks were only half the height of imported or generated stereo tracks. Imported stereo files had a "1" appended to the track name.
· Edit > Region Save did not save the cursor position.
· (OS X) Crash when quitting an empty project window, or when closing the main project window while a progress dialog was on screen.
· Numerous other interface fixes including Dependencies dialog, Keyboard Preferences and spurious lines drawn on waveform.
Imports and Exports:
· Support added for later versions of the optional FFmpeg library up to current FFmpeg HEAD. This should significantly improve FFmpeg support on Linux. FFmpeg downloads for Windows and Mac updated to v0.6. This fixes mono AAC files importing as stereo, though current 0.5 versions of FFmpeg will still work.
· Both FFmpeg and LAME should now be properly detected even when other versions of those libraries exist on the system.
· New warning (on by default) for importing uncompressed audio files. Better error messages when read-directly uncompressed files are missing.
· Imported ID3v2 metadata tags were removed when exporting without the Metadata Editor appearing (for example, when using an export command in Chains). Note: As a result of this fix, ID3v1 tags must now be written by exporting using (external program) and an installed LAME.
· U-Law/A-Law files with WAV headers now use the standard 18 byte fmt chunk, so should now be recognised by most telephony applications.
· Variable bit rate MP3s exported using "MP3 Files" were larger than necessary because using the bit reservoir was disabled.
· (OS X) Files imported from iTunes could create invalid characters in the .aup project file, causing an error when re-opening the project. Note: An error "reference to invalid character number" will still occur if re-opening a project created in previous Betas that contains such characters. To fix the issue, open a back-up copy of the .aup file in a text editor, turn off word wrap, then in the line indicated in the error message, remove the string of characters that starts with &# and ends with a semi-colon (;).
Other bug fixes:
· Nyquist effects: fixes for crashes, incorrect slider behaviour and better support for backslashes, double quotes and Unicode characters.
· (Windows and OS X) Processing of VST effects was substantially slower than in previous versions of Audacity.
· (OS X 10.5 PPC) A first-time installation of Audacity Beta would hang on launch if VST effects were detected.

Changes and improvements:
· Control Toolbar renamed to Transport Toolbar.
· Device Toolbar (on by default) now contains all input and output device choices, including host and recording channels. Input/output choices are no longer in Mixer Toolbar on Windows XP or some older operating systems. New Transport > Rescan Audio Devices menu item to refresh the device list.
· New "Sync-Lock Tracks" feature (turned on in the Tracks menu) to allow groups of audio and/or label tracks to retain synchronisation when the track length changes.
· Equalization: New "Manage Curves" dialog for importing and exporting curves.
· Noise Removal: New "Sensitivity" slider to adjust the noise threshold, and new option to isolate noise.
· New "Extended Import" Preferences for specifying different importers to open specific file extensions.
· Improved Automatic Crash Recovery with all project changes autosaved.
· MIDI tracks can be vertically zoomed, time shifted and display bar lines. Note: the channel selection buttons are not available in 1.3.13.
· Simpler installer with top-level "Audacity" folder.
