Also check our Wiki and Forum for more information. The latest release of Audacity is 1.3.5 (Beta). Because it is a work in progress and does not yet come with complete documentation or translations into foreign languages, it is recommended for more advanced users. See New Features in 1.3 for more information about the 1.3.x Beta series. This editor can record and play sounds and import and export WAV, AIFF, MP3, and OGG files. Edit your sounds using cut, copy, and paste features (with unlimited undo functionality), mix tracks, or apply effects to your recordings. The program also has a built-in amplitude-envelope editor, a customizable spectrogram mode, and a Frequency-Analysis window for audio-analysis applications. Built-in effects include bass Boost, wah wah, and noise removal, and the program also supports VST plug-in effects. This program is open-source, and this version adds tool tips, Keyboard Shortcuts, and OGG exporting and fixes some bugs. Version 1.2.4b has a Meter Toolbar added for monitoring volume levels during playback and recording, allows you to export multiple files at once, attempts to automatically correct latency in full-duplex recordings, and contains some bug fixes.
