Common Uses for MP3

MP3 is a widely adopted standard for compressed audio files, so it can be used in many different ways, including music and podcasts.


Almost every portable digital music player supports the MP3 audio format. By using the higher bit rates, for example 256 kbps, you can create an excellent quality audio file using a much smaller file size than with uncompressed audio.

You can also add metadata to the file so that when the output media file opens in many players (including iTunes) the common information, such as artist, album, and so on, appears.


The MP3 format’s wide range of supported bit rates makes it ideal for delivering podcasts at a variety of quality levels, making it possible for users to choose a file size and quality level they are comfortable with.

Note: For the most options when creating enhanced audio podcasts, use the MPEG-4 output format. You are able to add chapter and podcast markers with URLs and artwork to the output file. See Creating MPEG-4 Output Files for more information.
