This could be great news for projects like PodBible.mobi (making the PodBible audio Bible podcasts available to mobile phone users).
However, I have two questions you might be able to answer for me:
- What mobile phones can or can't play AMR files? So if you have a phone can you try downloading this AMR file and seeing if it plays, and report the make, model and result below, please!
- What exactly are the licensing issues with AMR there is a link on the Wikipedia site to an VoiceAge legal page, but I go cross-eyed trying to find out what that means for ordinary non-commercial users. Any comments on that would be helpful too!

Gsm format is worth a look. I think most mobiles support it and it could be converted on the fly on the server by using sox (providing your host has it installed).
What you need is an application that offers the user different file formats which are generated on the fly by the server, taking all the hard work away from conversion.
I imagine this is fairly straight forward, unfortunately I don't have the technical ability.

I am a total beginner when it comes to audio formats for mobiles, as best as I can make out from:
http://en.wikipedia.org/wiki/Adaptive_Multi-Rate
and http://en.wikipedia.org/wiki/Audio_file
It sounds to me as if maybe AMR is a form of GSM??? For this project we do not really have any one who can easily organise clever file format conversion on the fly, so we are likely to have to do the conversions manually or using batch files, so I'm keen to get the "right" format when we start.
With AMR I can even use a the lowest quality setting, and get something that sounds better than a phone call where the chapter is only 160KB which would be a tiny download for 3.5 minutes of audio!
