Frenquently asked questions

Q. How is "converting a Wave file into a MIDI file" different from "a Wave file into a MP3 file"?

A. A Wave file is a group of samples of digitized sound at many discrete points in time. A Wave file, due to its big file size, is often converted into a MP3 file deleting some parts which is not audible to human ear. However, MP3 still has wave sound.

Unlike a wave or MP3 file, a MIDI file is a sequence of commands designed to control one or more pieces of equipment. There is no sounds in MIDI files. For example, a command like "play C4 (Do in octave 4) for 1 second with the volume level of 100" consists of a MIDI file.

Converting a Wave file into a MIDI file can be analogied to "notating scores by listening to a music" The person listens to music, detects the pitch, length, volume level of the sound and notates down the musical information. (This ablility in computer science is called Music Recognition technology.)

As far as recognizing indivisual sound and get those musical information from a complex sound, there is no worthwhile software which does an incredible job. However, in case of monophonic sound, MuseBook Wav2Midi is proud of doing a better job converting a monophonic Wave file into a MIDI file among many other competitors.


Q. I have a Wave file but it says : Unsupported wave format. What format does MuseBook Wav2Midi support?

A. 44100Hz 16bit mono Wave file. When your Wave file satisfies MuseBook Wav2Midi's file format requirement, it results in best performance. If you have a different Wave file format, you can convert it into 44100Hz 16bit mono, then use it for MuseBook Wav2Midi.

Probably the easiest way to change file format is to use Window's Recorder. Or you can use some other special software designed for this purpose for better results.

Q. Can I convert a MP3 file to a MIDI file with MuseBook Wav2Midi?

A. If a MP3 file contains several different notes played together, it is not possible. However, if it has only monophonic sound, you can. To do so, you have to convert the MP3 file to a Wave file first then put it in MuseBook Wav2Midi for MIDI file result.

Q. There are some odd sounds in converted MIDI file from violin performance in audio CD. Why is it so?

A. Continuous notes of, for example, pitch C(Do) to D(Re), when the second D(Re) is sounded, there is still C(Do) sound remained. Eventually it sounds like C(Do) and D(Re) are played simultaneously, which eventually resutls in errors in pitch detection. Generally audio CD has reverb or echo effects applied like this to sound it better and more beautiful, and these effects may result in error in pitch detection in MuseBook Wav2Midi. A Wave file without echo effects is almost realized to MIDI sound with MuseBook Wav2Midi.
