In either of these apps, just choose the output settings you want to use. On Windows, the free version of dBpoweramp offers similar features. It can convert to and from a couple dozen audio formats. On the Mac, the best app, by far, is the free XLD. You can convert files using iTunes, but I find that it’s a lot easier to use dedicated apps. (It also supports some other formats, such as Audible audiobook formats, but you can’t convert to or from those formats.) ITunes, for example, supports the following formats: WAV, AIFF, Apple Lossless (ALAC), MP3 and AAC. You can convert these files to other formats using a variety of apps, but not every app can handle all formats.

As you use digital audio files, you may find that you have files in formats that aren’t compatible with the software or hardware you’re using.
