New Software Processor Can Transcribe Music From Any Performance Music to Your Eyes A new computer system can convert sound files into sheet music by creating a harmonic dictionary. It could conceivably convert this Global Symphony Orchestra production of "Star Wars" back into written notes. |

Method developed to identify musical notes at any venue The researchers start with a 'wav' file, a common format for audio recordings, and after applying the method they obtain a 'midi' file, a musical instrument communication protocol that makes it possible to visualise the sheet music and listen to the result. A team of telecommunications engineers from the University of Jaen (UJA) has created a new method to automatically detect and identify the musical notes in an audio file and generate sheet music. The system identifies the notes even when the type of instrument, musician, type of music or recording studio conditions vary. |

| Music Scene-Adaptive Harmonic Dictionary for Unsupervised Note-Event Detection Carabias-Orti, J.J.; Vera-Candeas, P.; Caadas-Quesada, F.J.; Ruiz-Reyes, N.; Telecommun. Eng. Dept., Univ. of Jaen, Jaen, Spain AbstractHarmonic decompositions are a powerful tool dealing with polyphonic music signals in some potential applications such as music visualization, music transcription and instrument recognition. The usefulness of a harmonic decomposition relies on the design of a proper harmonic dictionary. Music scene-adaptive harmonic atoms have been used with this purpose. These atoms are adapted to the musical instruments and to the music scene, including aspects related with the venue, musician, and other relevant acoustic properties. In this paper, an unsupervised process to obtain music scene-adaptive spectral patterns for each MIDI-note is proposed. Furthermore, the obtained harmonic dictionary is applied to note-event detection with matching pursuits. In the case of a music database that only consists of one-instrument signals, promising results (high accuracy and low error rate) have been achieved for note-event detection. |
