Audacity is a program for recording and editing sound files that’s easy to use, free, open-code and multiplatform.
Audacity is a simple, powerful program used to do large jobs: record live sound, convert tapes and recordings to digital sound or CD tracks, edit Ogg Vorbis, MP3, WAV files, cut, paste, splice and mix sounds, change the speed and pitch of a recording and more.
Audacity lets you manipulate different sound files in different ways, import and export files, combine them and create recordings from scratch and then export them to the most popular audio formats easily and quickly.
Audacity lets you include different effects, change the pitch without changing the tempo and vice versa, eliminate static, whistles or any background noise that affects the quality of the recording.
Audacity also lets you alter the frequencies using equaliser and FFT filters, amplify and normalise volume effects etc and incorporate new effects like echo, phaser, wahwah, reverse, etc.
When you manipulate audio files, the sound quality becomes an important factor. Audacity lets you manipulate 16-bit, 24-bit and 32-bit sounds with recording quality up to 96 Khz.
