Now that you have finished your project you need to have a way to take it with you. The default file format of Audacity is only playable in Audacity (useful for backing up your project) but you may want to export your audio into a format that can be listened to. We have 3 methods: MP3 (for playback on a computer or MP3 digital player), Standard Audio Cassette and Audio CD (for playback on standard CD music players)
