Audio Data Compression algorithms

Here's the story. I'm working on an 8 bit uP based audio system (well
primarily audio anyway) - max memory without paging is about 50k bytes
after all the hardware and code mapping has been done.
The problem lies with the fact that I need to use samples and 50k is only
gonna give me 2.27 seconds at a 22k sampling rate - about as much use as
an ashtray on a motorbike.
Therefore I need a data compression algorithm to get more mileage for my
memory - does anyone know where I get this info as it's a new field for
Is there a simple 8 bit DSP chip available to handle predefined
algorithms (part of the spec sheet?).
Btw, I've just scanned some of the AH archives as I've been unsubbed for
some weeks and I must say that I'm most dissapointed that very few jokes
have been aired, if fact I'm EXTREMELY ANGRY and your all very lucky
there's a little stretch of water between the UK and the US as under
normal circumstances I would have swam the Atlantic and given you all a
good spanking (I understand it's not illegal in the US - you get put away
for that sort of thing here).
Instead I'll just get my mum to phone you all up and shout abuse down the
phone. Nice try at the DC-9 joke Kevin. Not even a statement about our
Frank Bruno - the professional boxing ring rope tester! I also saw that
someone used the word BLOODY in there subject heading and my lawyers are
currently filing a copyright lawsuit.
Tut. tut - you really oughta' try better chaps
Please reply in private mail I'm still not subbed - flames more than
welcome as long as they don't singe my eyebrows.
Analogue content - Errrr.....
