as I understand the most used files/standartds for audio streaming(broadcasting) are RealAudio(ra), which is priprietary closed standard done by Real Networks and mp3, which is MPEG-1 layer III standard. (and AMR used for speech)
RAM is contaner format(metafile) specifiyng and contaiing audio/data stream it includes plus some other informations about streamed data.
MP4 is metafile specified by MPEG-4, with similar functionlity as RAM, which describe data stream it includes( audio, video..)
Am I right??
Thanx for reply
