In principle yes, but it's surprisingly tricky, to the extent that even some very simple analog audio things, like '70s-era voltage-controlled-oscillator synths, are only recently able to be emulated reasonably well. The research field is called "virtual analog synthesis". I'm not sure if there's a canonical overview, but some googling turns up this 2014 PhD thesis: http://lib.tkk.fi/Diss/2014/isbn9789526055862/isbn9789526055862.pdf http://lib.tkk.fi/Diss/2014/isbn9789526055862/isbn9789526055...
- dharma1 11y agoI've got a bunch of friends who have worked on this at some point, and I know some of the people cited in that PhD thesis. I can still hear the difference, even with state-of-the art current virtual analog emulations, like Diva. Have to say the gap is narrowing though. One approach I haven't seen used yet is using the latest AI/neural networks to learn and model the inherent nonlinearities in analog audio
- ShinyCyril 11y agoI wish I had picked that for my masters dissertation - ML + DSP seems like a really interesting area!
