I seem to remember this was the holy grail back in the 70s. It doesn't seem to be that common these days (Synclavier 2V, Alechemy 2?). Is that because the technology is called something else these days? Is it just a kind of wavetable were frames get repeated or granular?
And what apart from Synclavier 2 and Alchemy (was it in 1.5?) have it?

IL Harmor - https://www.youtube.com/watch?v=sOd8FutW-nk (seamless talks at 100 kph, be warned). The resynthesis is impressive though.

xoxos resyn2 from 2019, when i looked there were a few free instruments that used phase vocoding but limited features and implementation so i mak. it can do some clean things but i am no expert on programming for memory handling.
you come and go, you come and go. amitabha neither a follower nor a leader be tagore "where roads are made i lose my way" where there is certainty, consideration is absent.

Well, Parawave Rapid also has the resynthesise feature. Along with that, it should get granular pretty soon. It is a beast synth. Virtual analog, wavetables, samples, ROM, Granular, resynthesise and a little FM all available to use in 8 layers. Do check it out.

Resynthesis comes in many forms. Generally it's trying to analyse a sound and map it to some synthesis model.
E.g. by doing an FFT analysis on a sound or sample and then reproduce the sound by iFFT of the resulting spectrum. That would map it to an Additive synthesis model.
Maybe not even do the FFT and using Wave Tables (based on analysis/recordings of a sound). Might that be called resynthesis? Since it reconstructs a sound without actual replaying the full sample/recording.
The Hartmann Neuron was an attempt to move away from "classic" synthesis techniques, towards analysis and resynthesis of various properties of sounds.

I think I'll give that a try, thanks!

Kwurqx, I was thinking the same. Iget the feeling that resynthesis has moved on and now there are other techniques to do what would have been called resynthesis back in the day.

SeamlessR in the video says what Harmor is not creating wave tables (like Halion 6 does). But as he scrubs through sound (sound image, whatever you call it), at each moment it is just like a cycle of a wave table, right? It's just not handled like wave tables somehow?
Doing nothing is only fun when you have something you are supposed to do.

Not exactly resynthesis, but these folks use neural networks to analyze audio and create new content based on that analysis.

A developer is probably best placed to answer why this is different to wavetable synthesis, so take the following with a pinch of salt.Dirtgrain wrote: ↑Tue Jun 30, 2020 4:51 pm SeamlessR in the video says what Harmor is not creating wave tables (like Halion 6 does).

A limitation of wavetable (re)synthesis is that you can't capture/reproduce inharmonic overtones. Look at your wavetable oscillator under a spectrum analyser and all the energy in there will be at multiples of the fundamental frequency. Some wavetable synths implement additional functions with the potential to produce inharmonic tones (e.g. FMing one oscillator with another), but a 'raw' wavetable or any 'oscillator effect' that operates directly on the wavetable will never produce anything inharmonic.
Think about how oscillator sync works in a VA - no matter what the pitch of the synced oscillator is, the cycle being reset each time the master oscillator completes a cycle means it's always 'locked' to the master oscillator frequency. The same thing happens with the audio content in any wavetable. You're basically looping the wavetable frame at, for instance, 440 times per second for the A above middle C. You can consider this looping to be the master oscillator, while all the audio content inside the wavetable is 'synced' to it.
Harmor has no such limitation. There are a few methods of doing analysis/synthesis in the spectral domain, but Harmor seems to be driving a bank of sine waves. As he's scrubbing the sound, he's effectively telling the synth how many sine waves to play, what frequency they should be, and what amplitude they should be.
