Audacity 2.0.3 - Changelog

What's new in Audacity 2.0.3 RC1:

January 19th, 2013

Bug fixes for:

· Crash using Undo whilst time-shifting a track.
· Crash using Repair if the selection extended into an empty track.
· Export Multiple didn't prevent export if there was no audio or all audio was muted. This allowed export of small invalid files.
Time Track:
· Loop Play of a speeded-up track inserted silence.
· Playback and rendering was significantly inaccurate, creating audible and visual glitches.
Accessibility:
· The mnemonics character "&" was read out by screen readers in most of the Preferences choices.
· NVDA did not read static text in most dialogs. Text can now be read by using INSERT + B.
· JAWS and Window-eyes misread the "Duration" control in Silence Generator.
· Toolbar buttons could not be pressed by ENTER
· Other interface bug fixes.

Changes and Improvements:

· The SoX Resampler library (libsoxr) has replaced libresample in Audacity releases, offering both higher quality and greater speed. .
Time Tracks new features:
· "Set Range" now changes only the range of the Time Track, preserving the pitch/speed set by any existing warp points.
· Vertical scale added with options for linear and logarithmic display and interpolation.
· Upper and lower speed limits will now be remembered when saving and reopening a project in 2.0.3. Warp points in projects saved by previous Audacity versions will be correctly restored in 2.0.3.
· Warp points saved in a 2.0.3 project will be preserved if opened in previous versions but playback and display will be incorrect.
New effects:
· Studio Fade Out (uses a filtered "S" curve).
· Adjustable Fade (accessible effect for creating partial fades and adjustable fade shapes).
· Bass and Treble (replaces Bass Boost).
· Real sample rates up to 384000 Hz are now supported for playback and recording in high resolution devices (the maximum is up to 192000 Hz for Windows DirectSound host).
· Labeled Regions in Edit Menu is renamed to "Labeled Audio" and now allows splits to be placed at point labels. Labeled audio regions that touch without overlapping are treated as separate regions. Overlapping labeled audio regions are treated as a single region.
· Compilation: cmake is required in order to build libsoxr.
· New Croatian translation of Audacity.

What's new in Audacity 2.0.1 RC1:

June 25th, 2012

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 and Exports:
· 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.
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 to import files On-Demand (without seeking ability) when using the optional FFmpeg library.
· (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/manual/man/accessibility.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.
