Audacity is a free audio editor. You can record sounds, play sounds, import and export WAV, AIFF, and MP3 files, and more.
Use it to edit your sounds using Cut, Copy and Paste (with unlimited Undo), mix tracks together, or apply effects to your recordings.
It 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.
What's New:
VU Meters added for both playback and recording. Click on the recording meter to monitor the input without recording.
Export Multiple - new feature that lets you export multiple files at once, either by track, or split based on labels.
Attempt to automatically correct latency in full-duplex recordings. (This does not work perfectly, and is not yet supported on all systems. It will improve in future versions.)
Fixed a serious bug that could cause data loss when you save and then reload and re-edit an Audacity project containing repeated or duplicate data.
MP3 tags dialog will only pop up the first time you export as MP3; after that it will not pop up again as long as you have filled in at least one tag.
You can now add a label at the current playback position - in the Project menu, with a shortcut of Ctrl+M.
Clicking on a label now selects all of the tracks, making it easier to use the label track to recall selections. (ed -click readmore for the rest)
