While MP3, WAV and WMA are audio files, MIDI is not. MIDI files contain descriptions on how to make music, but not the music itself. When creating music with a MIDI file, all that is needed is a hardware or software synthesiser. A synthesiser is designed to follow the instructions contained in a MIDMI file, and so there is very little chance of getting an error. Because of this MIDI to MP3 conversion is quite simple, while MP3 to MIDI is like making sheer music out of complex recording. Unlike converting MIDI to MP3, there is a chance of getting wrong results. This tutorial will show you how to use an excellent and unique tool called WIDI Recognition System Professional, to convert MP3 format files to MIDI.
