Rdio's library has been upgraded to 320kbps AAC

Bitrate is meaningless if the used codec sucks. Variable bitrate AAC would've been the best option. 320CBR AAC is just overkill and wastes bytes. If they need 320kbps CBR on AAC to sound any good, then the codec they use sucks and they're better off with MP3. I've archived most of my music collection as 256kbps VBR AAC or FLAC.

I can't tell the difference between MP3 and AAC (max quality), but I've noticed (using a spectrum analyzer) that the AAC encoded file usually contains more audio data than the MP3 version. Especially the very high frequencies and low frequencies are simply cut with MP3 compression. AAC (using a good codec) keeps that audio data while also maintaining a smaller file size compared to MP3.

Does anyone know the bitrate of Pandora? Whatever it is, is beats XM radio. Never tried Rdio...might give it a go.

No into MP3's or AAC's. and stream is my last option.

But I have been playing lately with MP4's Music Videos and the sound is not bad at all.

1.- If the file contain only Music: it almost sound as clear as a CD.
2.- If the file containing Music & Video; is too small. Then the volume is low. [ Probably the Frame-Rate affect the Volume level too !? ]


- So What I do is:
Re-edit Video (Main Video) & Sound (Same level for all the tracks) to be as similar as the Radio Edit CD version & keep them as a custom MP4's or make a CD (20+- Tracks) or a DVD (30+- Tracks).

Just saying.

Pandora on the Web plays 64k AAC+ for free listeners and 192kbps for Pandora One subscribers. All in-home devices play 128kbps audio, and mobile devices receive a variety of different rates depending on the capability of the device and the network they are on, but never more than 64k AAC+.

I haven't tried extracting audio from mp4 however audiocoder could most probably do it & convert to whatever you want regardless listed below are handy tools to have

join vob file tool - use on dvd's to join all vobs then extract audio with audio coder ,works excellant

audiocoder 32 & 64bit comes in portable versions & is capable of extracting audio from vids

dvd audio extractor can't tell you where to get it *winks*

XM radio uses 30-50 kbps VBR AAC+ according to some people.
