The clip routines in the audio kernel extensions don't use AltiVec. It's possible, but not encouraged, to use AltiVec in the kernel (just like it's possible, but not encouraged to use floating point in the kernel, only more so).

Now I'm a little confused. Is this code handled in kernel space or user space? "This code" being the AudioConverter code.

All things considered, what is the best way to convert audio samples from 16 bit integer to 32 bit float? By hand, taking into account all of the previously mentioned potential pitfalls, or using the AudioConverter, or perhaps some other method?
