not that I know of. but if FPGA's are an option it could be built

easily ;)
USB-Audio is a very distinct standard and merging it with raw mp3/ogg

data i/o is IMHO not a good idea!
There are drivers and software for mp3-decoder hard/firm-ware (eg

ipodlinux.org ) - shared/locked memory is an issue on embedded devices,

and USB makes this even worse..!
I think the cheapest solution is to just /connect/ the

mp3-de/encoder/player output to a general purpose dsp & mixer chipset

and have them be two separate [usb] devices..
