New features in Audacity 1.3.2

New features in Audacity 1.3.0

Collapse/Expand Tracks

In Audacity 1.3, every track has an upward-pointing triangle at the bottom of the label area on the left side of the track.

Multiple clips per track

In Audacity 1.2, there is one audio 'clip' per track. There is no easy way to time-shift part of a track without moving the rest. In Audacity 1.3, you can split a single track into multiple clips. You can move these clips around between different tracks, making it easy to construct complex compositions out of hundreds of smaller audio samples.

Selection Bar

In Audacity 1.2, the current selection is contained in a status bar at the bottom of the window. In Audacity 1.3, this is replaced by a fully functional Selection Bar, which displays and controls the current selection (your choice of Start and End, or Start and Length), and the current audio position. The selection bar is fully editable - just click in any field and type to change the current selection precisely. In addition, many formatting options allow you to view times in different units, such as samples, CD frames, or NTSC video frames.

Improved Label Tracks

Label Tracks are Audacity's way for you to create markings and annotations within your project. In Audacity 1.3, Label Tracks are much improved, with support for overlapping labels, and support for modifying both the left and right edge of the label region just by clicking and dragging.

QuickTime and Audio Units on Mac

On Mac, Audacity can now import and audio file supported by Apple's QuickTime technology. This includes .MOV and .MP4 (AAC) files. Unfortunately encrypted audio files (such as those from the iTunes Music Store) cannot be imported directly into Audacity - Apple does not allow this to be done easily because it would be too easy to circumvent the encryption this way.

Also on Mac, Audacity now supports Audio Unit plug-ins. Audacity searches for Audio Units in the usual location, in the system or user's Library folder.
