Audacity 2.0.0 - Changelog

What's new in Audacity 2.0.0 RC2:

February 20th, 2012

Bug fixes since 1.3.14 Beta:
· Interface: (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:
· Fix 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 since 1.2.6:
· Labels now accept lower case "z".
· Windows Vista/7) Pressing Stop after recording could cause a crash.

New features:
· 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.

· for import/export of AC3/M4A/WMA and import of audio from video files.

What's new in Audacity 1.3.14 RC1:

December 8th, 2011

Bug fixes for:

Interface:
· Excessive delay occurred when typing into labels in long projects.
· Last digit of TimeText controls could not be manipulated in some formats.
· Play and Record shortcuts did not work after clicking in Device Toolbar.

Imports and Exports:
· MP2 files were not importable without FFmpeg library or an import rule.
· Files that could only be imported using FFmpeg imported as noise with no error message if FFmpeg was not available.
· Files containing PCM audio but an incorrect extension (such as MP3) caused a freeze.

Effects and Analysis:
· An empty command could be added to a Chain which then displayed a Nyquist error message when run.
· Plot Spectrum didn't preserve signal level if multiple tracks were analyzed.

Other bug fixes:
· Audacity has been provisionally fixed so that it can no longer create block files longer than the sample format or project format allows, and can no longer delete these, which led to data loss. Any overlong blocks found are preserved but "orphaned", so will appear as silence.
· Orphan block files were wrongly reported if cutting or copying to the clipboard then reopening the project in the same session.
· Fixed some crashes and incorrect movement of audio when dragging tracks.
· Data loss is now prevented when encountering a corrupted .aup file created in ANSI builds.

Changes and Improvements:
· Normalize: Faster processing and improved interface. Left-right balance in unsplit stereo tracks is now preserved by default, with a checkbox option provided to process 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 between time zero and first audio, and preserves audio before time zero. To retain silence before the audio starts, generate silence after render.
· Grouped some Edit Menu items into "Remove Audio" and "Clip Boundaries".
· CleanSpeech Mode removed from Interface Preferences (it still runs if it was enabled in a previous Audacity but can only be turned off there).

What's new in Audacity 1.3.13 RC2:

April 5th, 2011

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.
· Windows) Projects crashed when clicking rapidly inside the interface
· or when applying repeated effects towards the end of audio tracks.
· Windows) Some Unicode characters could not be typed into labels,
· or caused a freeze using some input methods.
· 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. 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.

Other bug fixes:
· Nyquist effects: fixes for crashes, incorrect slider behaviour and better
· support for backslashes, double quotes and Unicode characters.
· Processing of VST effects was substantially slower than
· in previous versions of Audacity.

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.
· Windows and Linux) The window Close button and other system close or
· shutdown commands now quit on closing the last window. File > Close now
· always clears to a new, empty project.

· WMA exports corrupted if they contained metadata
· Metadata Editor appeared before the Export window when exporting to any format

Effects:
· Crash or hang using Equalization on longer tracks
· Reverse did not reverse clip boundaries
· Nyquist: * Excessive memory consumption led to slow processing orcrashes * Values appearing in Nyquist effects text boxes were notalways the default or previously entered values * Errors running Nyquist effects in European locales wherecomma used as decimal separator
· VST effects remained in Effect menu even when re-scanned and no longer available
· Truncate Silence produced incorrect results if silences spanned a block boundary

Other bug fixes:
· Spurious "not writable/disk full" errors when saving projects
