I think I'm with Chris Wilson here. I find it a bit counterintuitive to have
"Wave" in the name at all, since to me, a wave is a time domain thing but the
WaveTable object holds frequency domain data (it's the OscillatorNode that
produces the wave, not the WaveTable object).

More precisely, the data held in the object is the Fourier series of a periodic
wave, but I guess PeriodicWaveFourierSeries is a bit too wordy to be practical?

As usual, interface naming is about the hardest thing you can do in computer
science ;)

Here's another thought: You could treat the WaveTable object in a way that is
independent of frequency/time domain. For instance, if the interface provided a
way to set the object state from a time domain signal as well as from a
frequency domain signal, and let it be up to the implementation to choose how
to store the data internally (could be frequency domain for hi quality
synthesis or time domain for low quality synthesis), and use FFT/IFFT
internally for the setters, as appropriate for the implementation.

If so, I think "PeriodicWave" would be a very fitting name.
