Hi list, some time ago a coder was asking about making such an app. I think it's on github.
I replied that I made one, and then I posted my very old project on github. terminator356/polyguitsynth It used FFTs, no windowing, but actually sort of worked. Latency was of course fundamentally an issue. I have always had my eye on this golden egg of a goal, but obviously it's tough, beyond my skills and time. So I sat down this weekend to try to modernize it. Qt, RtAudio, and especially the DSP. I looked at aubio but unfortunately its 'aubionotes' feature is (currently?) monophonic. Then I stumbled across this product, MIDI-Guitar from Jam Origins. I realize it's Windows product and this is Linux, but... Wow! What the... how the... The accuracy is astounding. The latency very low. Go and grab it, ye original poster who requested this! Very cheap price. I bought it. Worth every penny (I told them)! It runs flawlessly under wine with wineASIO - and - Jack2 which some said was broken in this respect... I read they use more than just spectral stuff. Like AI used in speech recognition and so on. Amazing what DSP audio and image coding can do these days. Any thoughts on coding techniques? I've read a lot of papers! Some say using FFTs + auto-correlation comparisons. Some say non-negative matrix. My head spins, but this team definitely deserves praise. Can open source come up with something? Cheers, Tim. _______________________________________________ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org https://lists.linuxaudio.org/listinfo/linux-audio-dev
