Is there any free way to convert Mp3 to MID?
MP3 is an audio recording. MID (MIDI) is the computer equivalent of sheet music. If your MP3 file has only a single instrument which is playing a single note at a time — voice, flute, horn — there is software which will attempt to figure out what’s being played and produce a MIDI score from it. If it’s anything more complicated, you would need a human to pick it apart into individual instruments playing individual parts, transcribe those parts, and reconstruct the mix — and that’s assuming your phone supports enough of the right instrument sounds to render this. Sorry, but your choices are either to find a MIDI rendering of that tune (and hope the phone can play it) or to pick another ringtone… or to buy a phone which can play MP3 ringtones.
