Actually, what's the main difference? There's a tiny quality difference, but I doubt you'll notice it -- especially at 8 kb/s. The main difference is speed. If there's an FPU present, then you'd need to check which version is the fastest. On x86, float is typically faster than fixed-point, but on the newer ARMs (with an FPU), fixed still tends to be faster. Jean-Marc
