Very cool – Spectrogram Pro (with super-smooth 60Hz update) Review

I really like this app, it's fun to be able to look at sound broken down into it's component frequencies... To be able to really see the harmonics in a voice or a cat purring. I do wish you could scroll the display back in time, or record it to a buffer and save it off as a movie. Though you can reduce the sampling rate and slow it down, which is almost as good.
