Abstract :
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. The authors help resolve the problem with 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.
