This editor can record and play sounds and import and export WAV, AIFF, MP3, and OGG files.

The program also has a built-in amplitude-envelope editor, a customizable spectrogram mode, and a frequency-analysis window for audio-analysis applications.
Changes between 2.0.2 and 2.0.3
Crash using Undo whilst time-shifting a track.
Crash using Repair if the selection extended into an empty track.
Export Multiple didn't prevent export if there was no audio or all audio was muted. This allowed export of small invalid files.
Loop Play of a speeded-up track inserted silence.
Playback and rendering was significantly inaccurate, creating audible and visual glitches.
The mnemonics character "&" was read out by screen readers in most of the Preferences choices.
NVDA did not read static text in most dialogs. Text can now be read by using INSERT + B.
JAWS and Window-eyes misread the "Duration" control in Silence Generator.
Toolbar buttons could not be pressed by ENTER
Other interface bug fixes.
