Changes and improvements in Audacity
- Control Toolbar renamed to Transport
- 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
- New “Extended Import” Preferences for
specifying different importers to open specific
- 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
- (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
- (OS X) Simpler installer with
top-level “Audacity” folder.
in Audacity 1.3.13
- 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
- Edit > Region Save did not save the cursor
- (Windows) Projects crashed when
clicking rapidly inside the interface or when
applying repeated effects towards the end of
- (Windows) Some Unicode characters
could not be typed into labels,or caused a
freeze using some input methods.
- (OS X) Crash when quitting an empty
project window, or when closing the main project
window while a progress dialog was on screen.
- 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. This should significantly improve FFmpeg
support on Linux. FFmpeg downloads for
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
- 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.
- (OS X) Files imported from iTunes
could create invalid characters in the.aup
project file, causing an error when re-opening
the project. Note: An error
“reference to invalid character number” will
still occur if re-opening a project created in
previous Betas that contains such characters. To
fix the issue, open a back-up copy of the.aup
file in a text editor, turn off word wrap, then
in the line indicated in the error message,
remove the string of characters that starts with
&# and ends with a semi-colon (;).
Other bug fixes:
- Nyquist effects: fixes for crashes,
incorrect slider behaviour and better support
for backslashes, double quotes and Unicode
- (Windows and OS X) Processing of
VST effects was substantially slower than in
previous versions of Audacity.
- (OS X 10.5 PPC) A first-time
installation of Audacity Beta would hang on
launch if VST effects were detected.
- (Linux) Recordings made with the
pulse device crashed or stalled when using
overdub and/or software playthrough.
- (Linux) Play-at-Speed crashed at
0.08 speed or lower if Audacity was configured
Audacity is a free
wave (audio) editor.
