Audacity is an audio tool that allows you to record and play sounds, import or export WAV, AIFF or MP3 files. Use it to edit your sounds using Cut, Copy and Paste (with unlimited Undo), mix tracks together, or apply effects to your recordings. Audacity 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, Wahwah, and Noise Removal, and it also supports VST plug-in effects.

Audacity supports uncompressed audio standards such as WAV and AIFF in addition to OGG and MP3 files. A full complement of basic effects such as reverb, delay, and compression are included. Virtual Studio Technology (VST), Linux Audio Developers Simple Plugin Architecture (LAPSDA), and Nyquist plug-ins also are available if you're looking to expand. Another eye-catching feature is the Beat Analyzer, which helps you peg the beats per minute of a phrase.

The performance of most functions is quick - even CPU-hogging tasks such as exporting to MP3 or adding complex effects. Though Audacity doesn't offer advanced effects or features out of the box, its usability and price set this freeware wonder above the crowd.

Audacity can record live audio through a microphone or mixer, or digitize recordings from other media. With some sound cards, and on any recent version of Windows, Audacity can also capture streaming audio.
