This was mild, compared to some of the go-arounds some people here have had in the past. Quote Link to comment Share on other sites More sharing options...

Some kind of weird episode of craziness. Quote Link to comment Share on other sites More sharing options...
Bill Yacey Posted June 3, 2020 Report Share Posted June 3, 2020 21 hours ago, David Burgess said: Here's one example of a "waveform" without amplitude. It looks like this: ________________________________________________________________ No sound. Not only one of us can cherry-pick our definitions. The way I view this is from an electronics viewpoint. Amplitude without change is DC voltage, and does not contain any wave form (alternating current) component. A flat line essentially amounts to atmospheric pressure, but because our ears equalize to this on both sides of the eardrum, it can be considered a zero baseline. In order to qualify as a wave, there has to be some sort of change in the amplitude vs time domain. Quote Link to comment Share on other sites More sharing options...
Bill Merkel Posted June 3, 2020 Report Share Posted June 3, 2020 john, when you superimpose two sine waves the result is periodic. what is the formula using the two sine waves that gives you the period that you see? Quote Link to comment Share on other sites More sharing options...

Scott Thurston Posted March 2, 2021 Report Share Posted March 2, 2021 In playing double stops on the cello, if perfectly in tune, my tuner app will display the exact Hz of the Tartini tone exactly when I stop the sound. Therefore my tuner heard the note. The tuner doesn’t think it’s a psycho-acustic or illusory phenomenon. The Tartini notes for each interval can be found in Cello Mind by Jensen and Chung.

Bill Yacey Posted March 3, 2021 Report Share Posted March 3, 2021 On 5/31/2020 at 6:25 AM, JohnCockburn said: no, my explanation is the correct one. Beats and combination tones have a different origin, and the former don't require nonlinearity. You can never see beats in an FFT because they are just an amplitude fluctuation. We can start throwing equations around if you like What is frequency, but a repetitive change in amplitude over time? Edit: Sorry, I thought this was a recent post until I looked closer at the date.

Shunyata Posted March 3, 2021 Author Report Share Posted March 3, 2021 FFT is designed to detect independent components. I there are two fundamental tones, that is what FFT will find. Your ear also hears the sum of those two fundamental tones, which is often perceived as "beats'. But mathematically FFT is incapable of hearing the beats.
