I originally was trying to talk about sound formats like AC3 and DTS which store sound in small packets of FFT results, instead of the equivalent which would be small groups of PCM samples. So people could do processing on FFT sound sources without having to push them to PCM before they can be modified. For simplicity, I was ignoring the extra compression which DTS and AC3 do. That is what I meant by the frequency domain instead of the direct sample domain. Both would have a time domain component.
