Sounds to notes?

Don't know, I'd actually like to know too. If not, however, pianos are pretty good for that, and you could always brush up on your dictation skills (or send the music to someone who is good a dictation). Any particular thing you want to use this for, if you don't mind my asking?

FFT?

Slightly OT: is there a program that can convert a song (like a .mp3) into a midi file? I''ve heard that''s impossible, but I don''t see why the song data can''t be run through an FFT and then filters and whatnot used to create a midi file that closely matches the original song.

How would a fast fourier transform help me at all? I need more specifics than that.

An MP3 inherently CANNOT be converted to an MIDI. I don't know where you heard this but it would be much easier to convert any format manually to an MIDI with as much precision that you could get than to try and make a program that converted any MP3, WAV, OGG, whatever format, to an MIDI. MIDI is like sheet music, MP3's, WAV's, etc, are a record of sound. It's like asking if there is a machine that will convert a record into sheet music.

(edit: yes I know some very simple songs could be converted to an MIDI, but any music that you might listen to cannot).

Notes are just specific frequencies. Do an FFT and you have the frequencies. Map the frequencies to notes. Poof.

I still don''t see why it won''t work that way.

I''m looking for already existing software that could do this, I don''t know enough to do it myself without a very descriptive tutorial or what-not. I have never worked with FFTs or sound editing.

The complexities of a song are too great to break down into a sequence of notes. A finished song has reverbs and other audio effects that MIDI''s have no way to store. Even if it did not, the complexities of breaking down the different notes which are all playing at the same time would be extremely difficult to implement. Plus, what would you do with voices?

Text-to-speech.

Peruse an online music store - musical instruments store - like Guitar Center or similar. No doubt they sell software too.

For reference, the A above middle C is 440 Hz. For more info see Pitch (music)

It seems that someone would have made a free piece of software for something so small and specific. I''m not looking for a great array of features.

It seems too pointless for somebody to have bothered both writing and releasing one. There are mechanical solutions to the problem, and I''ll bet distortion from the recording device would screw up the results.

I know it was said in jest, but look into text-to-speech programs. I''m sure there''s something that allows you to associate an action with a voice command. Record yourself at each pitch you are interested in, and map actions that correspond to their correct values. There are problems, but its probably worth a shot if you aren''t searching for a general solution.

Certainly you mean speech to text, and not text to speech?

With a mix of Audio Phonics Guitar Tuner and a Mic, you could find out which notes you are producing and manualy write down the notes..

Works perfect, thanks

Maybe I''ll write a program that cracks it and finds the note it is on currently.

Find one of those WAV to MIDI converter thingies (they DEFINITELY exist) and record your voice. I don''t know what instrument it''ll choose, but it ought to come up with the right notes, provided you sing in key.

Digital-ear is what you are looking for.
