“On high quality piano recordings its almost flawless”
If you have notes:
musescore
transkun transcriber (now also on MVSEP)
“it's the most accurate piano transcription algorithm ever trained and is unequalled in accuracy and absolute indifference to literally *any audio quality*
as long as the piano being transcribed is at A440 it'll spit out a 95 percent accurate transcription from virtually any recording no matter how absolute garbage it is”
