1/ I would like to know if I am computing (with rough precision) the bandwidth for MP3/AAC audio stream correctly. Parameters of the stream are:
The raw audio would be: 44100*128*2 = 11289600 bits/sec = 11025 kbit/sec = ~10.8 MBit/sec. I will count with 10:1 compression ratio (which I think can be more or less correct - but please correct me, if I am wrong) then approx. 1 Megabit/sec should be enough.
Sample rate: 44100,
Stream type: icecast (no metadata)
Codecs used: MP3 or AAC
2/ Is the computation correct? Because this means that for GPRS (~80 kbps), EDGE (~230kbps), UMTS (~384kbps) it does not make sense to even try those streams. If my computation is correct, then the only technology would be then the HDSPA, which starts on ~1.8 Mbps.
3/ Can someone give me good parameters for the streaming for the mobile audio streaming?
Thanks a lot
