[Ipodlinux-devel] Fast audio decoders

[Dan C. <da...@da...>]

Hi,

I don't have an iPod myself, but nonetheless I find your project 
interesting. While scouring the web, and the Hydrogen Audio forums in 
particular, I found a couple of interesting links:

"Embedded Decoder Brings Hardware Support For MPC!"
http://www.hydrogenaudio.org/index.php?s=&act=ST&f=2&t=4094

"RAM optmize version of Tremor for ARM"
http://www.hydrogenaudio.org/index.php?act=ST&f=9&t=6975

MPC is an audio codec which supposedly offers the best quality at 
relatively high bit rate (should be transparent at 160-170kbps). I 
believe you know what Tremor is ;) You should also take a look at FAAD. 
On my slow iMac with it's slow FPU, it uses significantly less CPU for 
decoding than any of the MP3 decoders. It just might be fast enough for 
the iPod :)

I hope you find this useful.
