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.
