Suppose I have a wave file (*.wav) with a piece for piano solo recorded in it. It's not a midi file, keep that in mind.
My question is: do you know of any plugin or any algorithm or any article in a journal dealing with detecting the time of each piano key being struck (each note being played)? Obviously the human mind recognizes each note unless the recording is of very low quality (perhaps very old), so in theory this should be possible — but has it been done yet?
Thanks!
If the sound is monophonic and the velocities of the keystrokes are well defined it is quite easy to create the (midi) events from the amplitude of the keystrokes. Most DAW offer such a function for years.
If the playing is polyphonic it gets way more difficult and the procedure needs more sophisticated algorithms. The last years a number of polyphonic audio to midi software has appeared and the error rate is improving.
You could use the "convert harmony to midi" feature if you have Ableton Live 9 to achieve this.
