My experience is that it doesn't do exactly what it says on the tin!!

Sweeney, dont even dream of this - IT JUST CANNOT BE DONE, no matter what anyone might say.

Well Shyam I would say it's certainly okay to dream about it!
But don't expect anything particularly earth shattering anytime soon. Certainly it is becoming more of a reality as the latest software from Celodyne (I think that's the name), Celemony is demonstrating, in analysing files in wav format. The trouble with mp3 files is that so much is stripped out of them to appease the great god "hard disk space" and his partner "download bandwidth" that it is a real struggle to recognise some of the tell tale acoustic footprints that individual instruments leave, and so converting mp3s to MIDI is really a pipe dream at the moment.
The stuff I've tried can make a stab at a reasonable conversion of a single voice but start adding chords and extra instruments and trouble ensues.
As someone posted in the past "try reconstructing the original cow from a beefburger!"
But who knows what the future holds, we are doing things that were thought impossible not that many years ago. I live in hope.
All the best,
JohnG.

Excellent link sus4chord, the changes in pitch with the spanish guitar were amazing, it looks like this guy, Peter Neubäcker , has made a massive breakthrough.  |

That was the one, it was posted in the old forum under "amazing technology" or something similar. Things certainly are moving forward. But you notice it isn't taking an acoustic guitar from within a mix of drums, piano, bass, sax etc. It's just a single instrument recorded fairly dry. The thing about all this that thrilled me most was that Peter Neubäcker is no young Whizz Kid but an older more experienced guy. It's the years of experience that I imagine got him where he is today. Grey hair rules OK. JohnG. |

Peter Neubäcker acknowledges that it works best with single polyphonic instruments (guitar, piano), but I view that as a starting point. Eventually, some really smart people are going to figure out how to break the sounds apart into their individual instruments. I know we've got a long way to go, but just look at how far we've already come. I believe it will happen. But for now, I figure out the instrument parts by just playing the WAV or MP3 files (usually slowed down), and use the technology God gave my - my ears and that gray matter that sits in between them. Sometimes it works well, other times, well, ... |

I know we've got a long way to go, but just look at how far we've already come. I believe it will happen. Yes, I'm sure it will, but from mp3s? I think so much is lost in conversion that that is going to take some while longer, if anyone does indeed bother to write the complex algorithms needed. Ears are the best method IMHO and a musical ability. I have to repeat a phrase and repeat again ... and again ... ! JohnG |
