Marginally useful

Sine wave freqency is right on. Some 3rd order harmonics, but not bad. Square wave has lots of ringing at around 1K, but is totally unrecognizable by 5K. Same with sawtooth. Triangle is good, and the frequency is right on at 1K; by 10K it is a sine wave approximation.

Comes up in A 440. Wish you could request a different particular note.
