Is anyone aware of a professional and accurate software program capable of converting audio files to midi files?

I believe that the Pro versions of Melodyne can do this.

The only software I've seen that attempts to do this is not very 'professional' (whatever that truly means) and certainly not very accurate.

And that's only on monophonic material. Polyphonic? Forget it.

the forthcoming version of melodyne will process polyphonic material

melodyne is the peak of this technology and can give amazing results, it isn't as easy as just pointing it at an MP3 and hoping for the best however

Yes, I've seen the impressive demo of the forthcoming Melodyne. Notably the demo material is very 'Melodyne-friendly'. Expecting it to perform as admirably against a track full of drums and vocals is, IMO, at best, optimistic. That's not to detract from the amazing achievement it represents.

I was catching up with progress on the Celemony site the other day. If I remember correctly:
1) The new DNA features have been delayed. They were due for release in Q4 2008, now towards the end of Q1 2009.
2) The polyphonic features will first be released in Melodyne Plugin which still won't yet feature MIDI conversion or control.

Looking forward to it nonetheless though.

I think that you may be able to do something like this in Ableton Live 7.

I read/heard somewhere that it's possible to import a piece of audio then export it in some way so that it chops the audio clip up into seperate samples that you can play back via midi data. It must load these samples into a sampler I would presume.

Of course, this could be done manually also but it may be of interest to some people.

Anyways, it's the only thing that I could think of anyway.

Not really sure why you would want to convert audio to midi anyway!

But what you're describing isn't audio to MIDI, slammers. It is simply audio slicing.

The Holy Grail of audio to MIDI would be to feed any (i.e. not just monophonic, or 'simple' polyphonic instrumentals) piece of music in at one and create a MIDI arrangement of it at the other. Then you could edit the performance, change instrumentation/sounds, etc. - i.e. not using any of the original audio itself.

But that is just what it remains at the moment - a Holy Grail. Quite what leap of technology it would take to do it is beyond my imagining!

Yes I agree. Is that what you meant OP?

If it is just monophonic audio to midi conversion, you've been able to do this in Logic since version 5. There are various plug-ins that do this too. If you want to do polyphonic stuff you'll have to wait for melodyne to get updated, and see how that fares. Any process to do this seems to require tweaking, both for pitch and timing.
