Audacity 2.0



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


* 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

* (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.
