<div dir="auto">I tried this some year ago, and it was an audible difference, which surprised me a lot. Now I don’t remember if the difference was heard in headphones but not speakers, or the other way around. And, at least my brain perceives a slight pitch change between saw and ramp!<br clear="all"><br clear="all"><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature">/Jonatan<br><a href="http://kymatica.com" target="_blank">http://kymatica.com</a></div></div></div><div><br></div><div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">sön 8 dec. 2024 kl. 23:00 skrev Chris McDowell via Synth-diy <<a href="mailto:synth-diy@synth-diy.org">synth-diy@synth-diy.org</a>>:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;padding-left:1ex;border-left-color:rgb(204,204,204)">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. <br>

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

>> Falling saw vs a rising ramp, is the difference audible? What is the definitive answer? 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?<br>
