Hi Bertrand

Thanks for those links, they do indeed clarify a few things. Should you 
play around with more Jaudiotagger features in future give us a sign, 
aTunes code did benefit from your current move :-)

>> I have seen some files with .ram ending however, so it is confusing. The Real Player creates files with .ra extension (just tried) and it seems to be the most common. For mp4 most common extension for audio files seems to be .m4a (iTunes, Winamp, Real Player and many others), not .aac . I think you confused the extension with the encoder (.m4a are encoded with AAC encoder for example). But I think .aac remain a valid extension for files created with the AAC encoder, but I don't know if a tag is supposed to be present (by memory I think .aac files are for raw audio file without tags and so).
