I am interested in this, but this was probably decades ago, wasn't it? I couldn't find anything on google.

I had this cepstrum on b&k xms, but never really found something, it's supposed to be good on gearboxes or signals with many harmonics families

Acoem also have it, you do a FFT of your FFT and if you delete a peak in Cepstrum and recalculate back to FFT a basic family is gone with all multiples, sort of fun if someone like to play with gbx's. It was like 30+ years ago during my nuke period. I attended a Santana concert live in Copenhagen :-) and I drove there in my Chevy Camaro '71 those were the days. All good vibrations :-)

So oli, did you do an fft of fft on the Santana music?  I do have to admit liking Santana a lot but it was just before my time really. rgds

Not really a handheld in those days was a Nicolet 100A at 15+Kg I think. One fell out of the door of a truck at a sister plant during transport and survived...... But the card connectors inside was a bit flaky, 400 lines CRT display :-) It was just before or around 2100 arrival.

I think he is still playing his guitar https://en.wikipedia.org/wiki/Carlos_Santana

We're thinking of a piping vibration, but that's looking a bit expensive. We're still commissioning, so training budgets are high, but won't be forever (hence I get my training in).
I was the guy that MarkL had to replace back in 2010 before I left for Oz (Occasionally referred to as that f****er who left a mess)-Sorry Mark!! To err is human, etc, etc



Not at all Vibguy-5 you left thing's grand for me.

Good to see you on the Board. a Sterling individual I may add gentlemen.
