What is Music Recognition or mp3 to MIDI conversion?

Wave, mp3 and midi are the most popular file formats for storing audio and music. Here we explain in brief why MIDI is very the different compared to Wave or MP3.

The most simple is Wave. It is a record of sound pressure on microphone on time. Any sound can be recorded as wave file, but wave does not allow editing sound components and occupies a lot of space. MP3 is a compressed wave. It takes several times less space, but does not allow separation and component editing as well.

In opposite, MIDI can store only musical sounds. MIDI is a command system, containing information about a note, about the instrument and its change, the length of pressing and so on. This kind of a record can easily be edited and takes less storage space than wave. More information about MIDI can be found on What is MIDI page (in English).

The difference between Wave and MIDI is much the same as that between the typed text and an its image. It is easy to convert typed text to image, but the reverse operation is much more laborious and ambiguous. For example, automatic recognition of hand-writing can't be accomplished without errors till now.

WIDI Recognition System and WIDI Audio To MIDI Plugins contain special algorithms that can analyze musical audio recordings and automatically reconstruct notation of musical piece. TrueTone Editor of WIDI Professional allows improving of recognition result by offering tools for efficient correction of any transcription errors.
