I tried many softwares for converting mp3 to midi. However the end result is not good. I have widi recognition system 3.0. Do I need a high end sound card for it currently I am having a Intel 815 motherboard and using the onboard sound card. I beleive I am not getting the settings right. I need to convert the mp3 files for Nokia ringtones 16 chords. What should I choose for the following options.
1) GM Patch instrument
2) Key
3) meter
4) minimal note duration ms
5) note detection method
6) Peak Polyphony

Or if there is a better program than this kindly let me know.

Hi Dhiram,

Maybe someone else will have some suggestions for you, but basically this type of conversion process is an inexact science.

MP3 is recorded audio.

MIDI is synthesised audio, sequences of notes, basically sheet music.

If a recording consists only of a single instrument, like an acoustic guitar or a piano, then transcription of the notes is complex, but possible.

But when you start talking about trying to transcribe a recording with multiple instruments, it takes a trained ear to perform the transcription. I remain very skeptical about software that claims to do it.

I tried the intelliScore demo, and it did better than I thought it would with a random MP3 file from my PC, but that's not saying much since my expectations were extremely low.

Bryce i've got another one for you.

I desperately need to "stream midi".
Basically that cannot be done, because midi is very dependant on the souncard. But i know it can be done, but am not sure where to start.
What i thought was that software like Helix-server (www.helixcomunity.org) would do the trick and convert the midi to something else on the fly. But no... Did not work. I triede several other products with the same result.
I've got customers that do not want to use mp3 as prelistening on a pc. They demand that the sound is as "midi"-like as possible. So i thought streaming was the easy way around it.
Most important is that the midi is NOT stored on the client cache-folder.

I have another idea though.
Windows media player fully support DRM.
Now the DRM we use on phones are very simple.
What i would love was to deliver a DRM wrapped midi file to the browser-client. The DRM should then do the trick of only letting this midi-file be played on this client.

How to do it... I have absolutely no idea...


Help me

Hi Lars,

I may be way off base here, but it seems to me that I've seen a few sites that use Macromedia Flash for this purpose.

I don't know how secure it is from a DRM perspective.

I wanted to find a good example of a site that was doing this, but instead found this tutorial that you might find helpful ...
