MP3, MP4, MOV, M4A and M4V format information

One of the more interesting aspects of educational podcasting is the variety of different formats used. In addition to the ubiquitous MP3 format, there are also audio/enhanced formats such as M4A and M4B as well as the MOV, MP4 and M4V video formats.

We have updated the podcast channel listings to include information about the format of every podcast listed, making it much easier to see "at a glance" the format used for a particular format. This is most useful where some podcast channels incorporate every format in their RSS feeds!

For every item listed in our podcast directory, we are using one of the following symbols:

for podcasts using the original MP3 format

for podcasts using the AAC format for audio/enhanced podcasts

for podcasts using the AAC format for audio/enhanced podcasts

for video podcasts using the new codec

for video podcasts using this general format

for video podcasts using this traditional format

We hope this much requested information is useful for users of our educational podcast directory.
