New features in Audacity 1.3

Beta version

Audacity 1.3 Beta is our new, not quite finished, development version which will be the basis of our next "stable" version.

Changes in Audacity 1.3.10

Bug fixes for:
Imports and Exports:
  • Freeze importing audio files when Default View Mode set to Pitch (EAC)
  • Simultaneous On-Demand imports sorted incorrectly
  • WAV or AIFF files imported as noise if Preferences set to copy in the data at 24-bit quality
  • 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 or crashes
    • Values appearing in text boxes not always the default or previously entered values
    • Errors running in European locales where comma 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
  • Playing, rendering or exporting multiple tracks led to desynchronized playback or loss of audio data
  • Crash opening Preferences when no recording and/or playback devices enabled or connected
  • Preferences window: OK button did not respond to ENTER when a tab selected in left-hand panel
  • Mixer Board solo button handling
  • (Windows) After a period launching correctly, Audacity sometimes did not come up on top at launch
  • (Mac OS X) Correctly installed Help folder could not be found
  • (Mac OS X and Linux) Output slider could affect VU playback meter which then did not reflect actual waveform volume level
  • (Linux) Undoing or redoing a label edit could cause a crash
Changes and improvements:
  • Linked audio and label tracks disabled until a future Beta version so they can be bug fixed
  • Input volume slider will be disabled if it doesn't have proper control of system slider; use the system slider instead
  • Proper support for copying/pasting label-with-audio including label text; new Edit > Paste Text to New Label menu item to paste system clipboard
  • Contrast Tool now modeless, more intuitive handling of multiple project windows, various other minor improvements

Please be aware of Known Issues at Release (also viewable in the included README.txt).

New in Audacity 1.3.9

  • DTMF generator defaulted to zero duration on open
  • Unwanted interactions between linked audio and label tracks
  • (Windows XP)  Failure to launch on some machines due to "incorrect configuration" issue
