Anyone know of a decent freeware mp3 to midi converter?

A human brain?
Honestly, I've never run across anything that came close to doing a good job. Trying to convert a final product back to what is basically sheet music is something computers just aren't that good at.

Taking an analog recording and converting into a a synthesized format like MIDI is going to be difficult if not impossible. The problem is that MIDI is synthesized music, a set of instructions for the computer, while MP3 is a recording, and a highly compressed one at that. Converting to another recorded format like wav, or aac is simple, though.
It's kind of like taking your winning photo and wanting to make a vector based adobe illustrator file out of it. The results are not likely to be what you expect. (Not sure if that comparision really works or not.)
What is the reason you need it as a MIDI file? Perhaps there is some other solution. |

I am 99.9% sure this can not be done. What is your reason for wanting to convert ?

I think what they are trying to do is convert an MP3 to Midi for a ring tone.
Am I correct? |

If that is the case, most recent cellphones can use an MP3 as a ringtone. I have a number of MP3 clips I use as ringtones. I edit out a 20 or 30 second sample of the file using Audacity. (A free and open-source audio editor) |

You are correct about phones playing MP3's but majority of that only started last year. You could get them before that but you would be paying an arm and a leg for it. Now days you can get them for nearly nothing.
The sound quality of converting a mp3 to a MIDI is virtually undetectable by the human ear. Putting a song into mp3 format is already compressing the file so it's nothing that you’re not already used too. Think of it like photography... The songs on a CD (that you buy) are like RAW images (or RAW songs) When you convert (RIP a CD) to MP3 format it’s like using the Save for web conversion. The same goes from MP3 to MIDI. To you're ears it will sound normal but pull it up on the computer and you will see a difference (If you have an editing program that will show you)

MIDI isn't an equivalent compression format to MP3. It is more like going from a bitstream JPEG image to a vector format. MIDI is essentially which notes to play, not what amplitude to output. In a MIDI format you specify a note and a 'voice' (piano, guitar etc) and the note gets synthesized. Nothing like mp3 at all, so very difficult to automatically convert between.

You are correct but I was just trying to explain it the easiest way that everyone would understand. My point is your going from Large to small to equal to. Once the sound has gone down to mp3 format you're to going to digitally enhance the sound back to it's original state or anything better than mp3 format.

is fundamentally wrong. You are not going to be able to convert an mp3 to MIDI in any meaningful way.
mp3 is a compressed encoding of sampled data.
midi is a format to describe how to synthesize sound.
Very different. You can convert from midi to mp3, but not the other way, automatically.
Put another way, mp3 stores audio data, midi stores information on what notes to play, but no audio data.

A MIDI file is the digital equivalent of a player-piano roll or the toothed cylinder in a music box.
You might be able to convert a simple theme played on a single instrument to MIDI, but as soom as you have two or more notes playing simultaneously you are talking supercomputer-type power needed to separate and analyze the various instruments, and generate what is essentially a conductor's score. |

Right click and save as
Slayer - Raining Blood.mid
This was a MP3 that I was able to convert to a mid file a while back.

With a little more fidelity... Slayer still sounds pretty much as grating to the ears :-)

Sounds like Slayer being played on a cheap monophonic keyboard. (Cuz it's MIDI) It may be playing Slayer but it's not like listening to Slayer.
SLAYER ROCKS!!!!!! |

I've used this program for over 5 years to do just that.
//www.intelliscore.net/index.html
The ensemble edition is capable of separating out the various instruments into their own track. It's not perfect, but it does a pretty amazing job. The resulting midi file WILL need to be edited in your choice of MIDI editor. I use Cakewalk.
EDIT:
Sorry, just re-read John's original post. This software is certainly NOT freeware. I doubt that there are any free programs around that will do this with any degree of accuracy at all. I know I wouldn't put the time and effort into writing it just to give it away.

Well darn it's under $200 and doesn't even need a supercomputer -- that's pretty good. From the MIDI file it should be possible to generate a printed score ... |

OK... My objective here was for the purpose of ringtones for my cell phone. I purchased the DataPilot Cell Phone Data Transfer Suite at BestBuy. According to the box and instructions, it says I can transfer RTTTL, MIDI, and MP3 files with the ringtone composer portion of the software. After spending several hours with the instructions, I have not been able to figure out how to make it work with MP3 files. I think this software is possibly false advertised and won't really work as described. I sent email to the tech support desk outlining my problem and lack of proper instructions/documentation, and I got an email back this morning from a technician who had copied/pasted the same instructions to me that don't work.
Has anyone tried this software?

I edit my MP3 clips in Audacity. My wife and daughter's phones will connect directly to the PC with USB, so I can drag and drop files directly into theirs. For mine, I transfer them to my phone with the bluetooth file transfer.
If you need one, you can buy a USB bluetooth dongle for $15-25. |
