> We find that the model is able to reproduce a sound nearly indistinguishable from the real analog pedal. Maybe for the average person or buried in the mix, but the audio samples were easy to distinguish for me as a guitarist. The NN samples unnatural decay were a dead give away.

Also the pretty obvious quantization noise which sounds as if the effect had a wide bandwidth, which is impossible with their op-amps at these gains.

Yeah - this was clearly audible on my phone speakers, especially during more muddy / multi-note sequences. While it may not be able to emulate a real pedal to create one’s own sound, it would be interesting / fun for amateurs when applied as a post-filter with an interface that says “make this sound like X famous incredible track” coming out of a stock guitar signal.

Confirmation bias overrides ear training. Always have an unbiased tone junkie do your blind test.

Even as a regular Joe it was easy for me to distinguish them, and though I was not very confident in my guess, I did guess correctly as well. It was close though, so maybe for say a beginner on a shoe-string budget it would be perfectly acceptable.

Agreed, the NN had that "digital" sound you typically get from a simulated tube screamer, such as in a POD HD or something. Very impressive given it's from a NN, but I specifically moved to analog for that reason.

Yeah, real pedal sounds much "better" but maybe we're just used to how they sound.

Not really a guitarist, but listening to them I couldn't hear a specific difference. Yet I still liked one of them more. And when I clicked "reveal" that one was the real one, turns out.

  the real one has longer fading tones, the one generated by machine learning cuts the sound abruptly. it seems easy for me to differentiate them and I’m a beginner with guitars (~1 month, so I’m your average Joe). it’s pretty good though, I’m sure it can be improved greatly.

I could also tell the difference, but I preferred the more staccato sound of the NN version.
