[sdiy] saw vs ramp, audible?

[Chris McDowell]

Hah right, I should specify I mean theoretically! It's clear to me that a speaker or room or overlaid waveform could reveal which tooth we were dealing with. 

Thanks for the responses. I am happy to upend my understanding of harmonics whenever necessary, but glad I don't have to today. 

this came up because I was thinking about someone's post here or on their blog about shifting the phase of harmonics and how that can yield wave forms that look very different, but sound the same. I googled "phase shift audible waveform" or something like that to try to find the article. maybe someone remembers where that is or wrote it themselves :) 

Cheers,
Chris

I have believed for years that the difference is not audible, that maximum disconinuity followed by minimum discontinuity is what a saw or ramp is, and inverted but otherwise identical waveforms sound identical. I came across a wealth of traffic online today arguing against that. I'm super skeptical. Folks' arguments were passionate but not complete in a way that could convince me. What is the real deal here?
