Audacity 2.0.1 released June 29, 2012
- Changes in 2.0.1 as compared with 2.0.0
- Issues with 2.0.1 which were known at time of release.
Changes between 2.0.0 and 2.0.1
Imports, Exports and Files
- 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.
- 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
- 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/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.
Known Issues at time of Release
- Projects with more than 2^31 samples (just over 13.5 hours at 44100 Hz) will not re-open correctly. [*] Higher sample rates mean proportionally shorter times - so just over 6 hours at 96,000 Hz. We know the cause, and do intend to address this bug. Workaround: Before saving or closing the project, export to audio files of appropriate size, or cut and paste sections of audio containing less than 2^31 samples to new Audacity projects and save those.
Problems reopening, saving or crashing in projects
The following problems are very rare, but have the potential for losing data. The developers have not yet been able to reproduce these problems so please write to our feedback address if you encounter any of these symptoms.
- When attempting to reopen the project normally: [LIST]
[li] The .aup project file was not saved (or incompletely saved, giving a "line number" error).
[/li][li] Audio that was there previously is silenced.
[/li][li] "Missing Audio Data Block File(s)", "Problems Reading Sequence Tags" or "Orphan Block File(s)" errors are reported. If you see these errors, please choose the options to "Treat missing audio as silence" or "Continue without deleting" the orphans.
[/li][li] Note: To avoid any problems, export a WAV or AIFF file from your project before closing it, then you can import the WAV again if the project becomes damaged.
[ul] When working in the project:
[li] Errors occur when saving the project or when Audacity autosaves, perhaps wrongly suggesting the disk is full or not writable (if this happens, try exporting the audio as WAV).
[/li][li] Unwanted renaming or moving of .au files within the project.
[/li][li] Multiple or duplicated .aup files or project folders appear within the same project.
[/li][li] Unexplained crashes or corrupted audio occurs (note this can happen if the computer is low on memory or disk space).
