This method would be the simplest and cheapest to implement, but wouldn't it
be more common for the clock frequency to remain constant (44.1kHz or
whatever) and use some scaling algorithm to derive the output waveform from
the wavetable data? That way the output from the digital oscillator could
remain digital for effects processing and S/PDIF outputs etc.
