> 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.

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.

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.

[sailfast]

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.

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

[jefftk]

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.

[zuppy]

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.

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.

[zwieback]

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