[sdiy] saw vs ramp, audible?

[Mike Bryant]

I think one possible explanation for a sound variation is the difference in non-linearity of the speaker or headphone when it's driven hard inwards or hard outwards by the sawtooth edge.  Apply a little treble cut and I bet they sound the same then.

Subject: [sdiy] saw vs ramp, audible?

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?

Cheers,
Chris McDowell
