Audacity is a multi-track audio editor that can be used for recording, playback, mixing, copying CDs or tapes, and creating podcasts. Audacity is very versatile, and can meet the needs of many multimedia projects. It also includes some basic automation capability in the form of batch processing that allows you to set up a chain of events.
Audacity also includes a large number of effects, generators, and analysis tools that let you take your recordings to the next level. If you need to duck one or more tracks, change pitch, remove noise, or apply one of the many filters, Audacity can handle it.
Audacity is free; donations are encouraged.
