Projects / Audacity


Audacity is a cross-platform multitrack audio editor. It allows you to record sounds directly or to import Ogg, WAV, AIFF, AU, IRCAM, or MP3 files. It features a few simple effects, all of the editing features you should need, and unlimited undo. The audio I/O uses PortAudio, which fully supports OSS, Mac OS X CoreAudio, and Windows WMME, and can be compiled with support for ALSA and Jack.

            Audacity is quite powerful for a multitrack editor
            It may not be ProTools but Audacity is a cool piece of software. Does what most people will need it for.

            Highly useful
            I've used this to record my own mp3's of myself playing my guitar. I can take these to my friend's house and then burn them to a CD. Then I can play this CD for my friends and family.

            I can also import .WAV files recorded from video games emulators and then transmute them into .mp3's and put those onto CD's for playing role-playing games.

            I havn't seen any bugs as of yet, and I'm glad they have a linux version, because I'll be abandoning Windows ASAP.

            Overall, it's awesome. I've seen and done so many things with it (recording songs, exporting .WAV files to .mp3, recording voice-acting for Flash movies, etc...). Keep up the good work; I might just cry if it disappears.

            Very nice program!
            This is one of the best examples of just how far free
            software has come over the years. Audacity packs a lot of
            punch and is easily one of the "killer apps" of the free
            software revolution.
