Depends how slow is slow :). As Paul said, 'trivial' is the cheapest
method (but this will *definitely* lead to quite obvious audible
artifacts in certain cases; if you're lucky, you may happen never to
play any affected audio). On my Vaio P, which has a very slow Atom CPU,
I use speex-float-0 , which doesn't seem to cause any audible problems
for me and gets the CPU usage down enough that playing back high def
video doesn't max it out.
