[sdiy] saw vs ramp, audible?

[René Schmitz]

It's so easy to fool our senses. I do remember how back in school our 
chemistry teacher gave us a

vial of "Cherry Water" to perform a smell test. Only to later reveal 
that it was tap water. He drove that point home.

I smelled the cherries.  As did most of my class mates.


This is how you hear the gold plating on the power cable. You hear what 
you believe you hear.


I did try this with audacity, generate a 480Hz sawtooth (at 48k SR it's 
not too horribly aliased), and created an inverted copy.

I do perceive a difference, but maybe I'm sniffing the cherry water here.


What you need is a randomized double blind test.


Best,

  René

>>> 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?
