A new method to detect and identify music notes in an audio file and generate music sheet was developed by a group of telecommunication engineers from the University of Jaen.

“We propose an automatic system to detect and transcribe musical notes for one-instrument musical signals which, unlike other methods, is capable of adapting to the music scene,” explained Julio Jose Carabias, a researcher from the Department of Telecommunications Engineering at the University of Jaen

“Automatic music transcription has many practical applications for musicological analysis and is of enormous assistance, for example, in recovering musical content, separating audio sources and codifying or converting audio files,” Carabias says.

The system does not require training with a musical database. It determine the note or ’spectral pattern’ of the musical notes of an instrument used to compile a harmonic dictionary.

However, the system can only be applied to files with one sole instrument at present but the researchers said that they are already investigating how it can be applied to several.
