Hello everbody ! Can you please help in converting the incoming audio signal into midinotes 😉 Perhaps thru pitch to frequency to control osc but this is only monophonic 🙁 how to do this polyphonic ? Thanx

polyphonic pitch detection is really an artform requiring lots of technical knowledge. This won't come shipped in SM soon I'm afraid.

Currently the only way to do that is to pass the data through the brain of a trained musician 😉 If anyone ever manages to write software that can do it properly I will have to find another job! 😮

Heh, just as you say that, I may have to add that I was talking about monophonic pitch detection. Polyphonic is a totally different beast.

I depends on how you want to do it and also requires a lot of knowledge about both midi and the audio so unless you know what your doing this will probably be a very hard task but it is possible.
If you want to do this for your own use there is already a few programs that will do this quite well already.

Really? Where? 😮

well theres programs that work ok then i guess, just type in something like audio to midi to google search and you will get a load of results, i got a few software trial versions a while back which worked ok but anything really complex wouldn't really work that well but stuff like simple basslines worked fine. I no longer have the programs though so i couldn't tell you which ones to get, its just a case of finding one that works well for what you want really.

thanx anyway 🙂 Ever tried ts-audiotomidi? Perfect for polyphonic audio to midi (playing chords with guitar). The input frequency curve is divided into midi notes with eq filtered and treshold control. Works fine but overtones are not filtered out so playing one tone gives three or more on the bass strings. I try to build this with synthmaker also it is quite complex. Any suggestions to start with ?

I sense that this could be a FFT-Job, deviding the frequency range in pitches, finding the fundamental pitch and then checking out the harmonics. Of course, to be polyphonic, you would have to have that in a way that work with more than one fundamental pitch at once. Might also be that you need iFFT, but that I don't know for sure.

Yeah that was one of the better apps i found, it was quite good i guess. After trying all the apps out i figured it was simpler to just make my own basslines and stuff, unless you want to turn a sample based song into a ringtone or something then theres not much point in using audio to midi apps, but thats just my opinion, could be usefull every now and then though i guess. 😀

MIDI ringtones have been my main income for nearly 3 years. Last time I tried any audio to midi apps they couldn't even reliably transcribe a mono part, as strong harmonics would often be misinterpreted as the fundamental.. full mixes stood no chance at all!

Is it still available? A quick google says it isn't..
If you want a good test, give these apps the first 30 seconds of Danny Elfman's Simpsons theme tune, and see what comes out 😈 (please post the results!)

Well i doubt that the current audio to midi software would give a decent result anyway but they have probably got a bit better, the problem is, im guessing anyway is that the audio is combined in most tracks so to get the best results it would require seperate audio channels. They do however do what they say they do even if it's not the best results, if you work with ringtones though having a decent audio to midi app would probably help a lot as it could quickly give you a base midi file which you could then re-sequence to sound more correct.

It would have to be light years in advance of anything I have used so far to have any chance of helping. Knocking a bad MIDI into acceptable shape usually takes me longer than doing it from scratch.. 😉

Ahh ok then, i might make one at some point in VST form, i doubt it will end up being anything great though 😀

TS Audio to MIDI claims to convert polyphonic audio but i haven't had chance to try it out yet, I will try it tonite and let you know the results.
