Not only is this enough to encode/decode in real-time, but you can probably do ~50 channels (or more) at the the same time.

On a 300 MHz machine, that is a throughput of 6 floating point operations per cycle. Perhaps they are talking about multiple processors or it applies only if you use a special instruction that does more work than usual?
