Abstract (en)
[origin: WO2006079813A1] A digitised audio signal (310) , such as an amateur's singing, and a digital guide audio signal (312) are supplied to a time alignment process (320) that produces a time-aligned new signal (330) , time-aligned to the guide signal. Pitch along the time-aligned new signal (330) and along the guide signal (312) is measured in processes (340) and (345) which supply these measurement to a pitch adjustment calculator (370) which calculates a pitch correction factor Cs (Fps) from these measurements and the nearest octave ratio of the signal A pitch changing process (380) modulates the pitch of the time-aligned new signal (330) to produce a time-aligned and pitch adjusted new signal (390) .
