converting wavs to midi

[Mark Krutke]

Hi Folks,

Does anyone know of a free program that I could use to convert wavs to midi files? I've been experimenting with ringtones on my cell phone, but for me they must be midi files for my phone to accept them.

Thanks, mark

WAV files are sound files. They have no musical structure.

MIDI files are like sheet music for a computer. They tell it what notes to play, on what instruments, in time.

Converting MIDI to WAV is fairly simple. You just play the MIDI file and record the resulting sound.

Converting WAV to MIDI is nearly impossible. It's not hard for a human to pick out the guitar part and separate it from the piano, but computers don't know how to listen to music.

The program you need is called a MIDI sequencer. Google "free MIDI sequencer" but I don't know which free one is best.

I have no idea whether this site might help you, I stumbled on it while surfing the net.
Let me know what you find or if it helps. http://www.geocities.com/alantan75/wave2midi.html

Mark:
What Bobby Lee said is accurate. I've tried several of the so called 'wave to midi' converters. (I haven't tried any of the ones listed in Johnny's link) They are basically a waste of time. IF you want to convert a single note melody to midi, the converters will translate something recognizable.....barely. Polyphonic? Forget it.
When I want to make midi files, I use a program called Anvil Studio. http://www.anvilstudio.com/
The free version allows full use of the midi sequencer and is easy to use. I have a tutorial on how to use it which I wrote for folks over on the Gamemaker forum. http://www.geocities.com/midi_melodies/index.html

There have been a few programs that could read a single note audio file and create a midi
equivalent.

These were usually in the very high end midi sequencer / digital audio packages.
So it exists, I just am not sure whats available now.

Something here shouldbe good for singing or playing a line and getting a close midi aproximation.<FONT SIZE=1 COLOR="#8e236b"><p align=CENTER>[This message was edited by David L. Donald on 06 December 2004 at 09:04 AM.]</p></FONT>

Or you could just create your own MIDI sequence by playing or programming the melody of the tune you want. Should take about four or five minutes if you step-enter; real time if you play it on a MIDI keyboard.

[Ray Minich]

For the unfamiliar, MIDI is just a serial datastream at 31,250 baud. Each byte occupies 10 bits so 3125 bytes max can be sent per second. A MIDI message is a packet of data that fully specifies an event (like "play a note"). It's what's at the receiving end of the data stream that plays the notes (or launches fireworks) by executing MIDI commands.

Power Tracks Pro Audio is an inexpensive sequencer that has a pitch to midi converter, but as everyone says, the results are usually not great. If you sing or play a simple single note tune it will convert it, you will likely have to do some tweaking after.
