The catch is it was being discussed a SRC to 48kHz, which when you
have the choice between doing so using whatever chip is onboard a
cheap piece of equipment, or doing so via libsamplerate it is
typically a far better idea to use libsamplerate as you will get a
cleaner conversion in most every case.
