Audacity
Fortunately, there is a great free audio tool available that will help you convert audio into any format. In our case, we need to convert to .mp3, .ogg, and .wav.
Audacity is an open source, cross-platform project designed to bring sophisticated audio editing to the desktop. The current version works on Mac, Windows, and Linux.
Figure 7-2 shows a sample screen from Audacity. When you load a sound into Audacity, it displays the waveform of the sound. You can manipulate the sound in many ways, including trimming, splitting, and duplicating, and then add effects such as fade, echo, reverse, and so on. After editing a sound, you export it to the sound format that you would like to create. In our case, that would be .ogg, .wav, and .mp3.
Note
We don’t have the space here to fully describe how to use an audio tool like Audacity, but we do need to give you one caveat: the distributed version of Audacity does not support the export of audio in the .mp3 format. To export .mp3 audio, you will need to download the LAME .mp3 encoder. LAME is also an open source project.
