     // Use exact powers of two for resampling rates. They don't have
     // to be related to our actual samplerate: the resampler only
     // cares about the ratio, but it only accepts integer source and
     // target rates, and if we start from the actual samplerate we
     // risk getting non-integer rates for lower octaves
