The mobile phone industry has a problem with conversion from MIDI to SP-MIDI, which handles specific polyphonic limits. Simple specific polyphonic reduction algorithms, such as note-stealing, may lose or interrupt important musical information. Therefore, we present a phrase-stealing algorithm that drops the perceptually least important notes and preserves the most important phrases. Tests show that listeners reacted positively to this solution.
Index Terms:
MIDI, SP-MIDI, transcoding, mobile phones, ring tones, phrase stealing, polyphony reduction
