Oversampling tone generator?

Is there any special reason that the tone-generator in 0.5 beta supports 32x oversampling?  I'd understand if it were generating a saw wave or something, but 32x oversampling for a sine wave?  I don't get it!  A sine wave contains no extra harmonics that could possibly alias, so what does oversampling achieve except a massive waste of CPU?  Anyway, I doubt most users will use the tone generator, but still...

(oh yeah, Foobar2000 is awesome!)

To be more accurate for high frequency sine waves, for no apparent reason other than just because he can? Heh, heh, heh.

Yeah, I guess I'll have to agree with the "just because he can" theory.  However, oversampling won't be any more accurate for high frequencies than just simply generating a sine wave.  Maybe he's secretly going to turn Foobar2000 into a software synth (that uses saw and square waves, that *do* benefit from oversampling)?

That was the first question I had when I saw it - it's just kind of there under "standard inputs".  Use tone://freq under "add location" to try it out.  Uh, maybe it's for musicians who want to tune to Foobar2000?

Not only that, but the tone generator has a variable sampling rate output, and the resampling plugin would do a much better job of reducing a high sampling rate to a lower one anyways. 

Care to enlighten us, Peter?
