Introduce a pulse length control mechanism to generate virtual multi-level output pulses for a Class-D Amplifier, which has only 2 physical output levels. Typically a Sigma-Delta-Modulator converts the input signal into high frequency low bit rate. The disclosed invention adds functions to transform the SDM signal into pulses with equivalent multi-level time-voltage areas and adds a pulse-length-control mechanism to produce various output pulse patterns, where the summations of the positive and negative pulses, within one sampling period, result in time-voltage area values, corresponding to 3 or more digital levels. Thus the invention produces higher signal quality at lower sampling rates.

A digitised audio signal, such as an amateur's singing, and a digital guide audio signal are supplied to a time alignment process that produces a time-aligned new signal, time-aligned to the guide signal. Pitch along the time-aligned new signal and along the guide signal is measured in processes and which supply these measurement to a pitch adjustment calculator which calculates a pitch correction factor C′s(Fps) from these measurements and the nearest octave ratio of the signals. A pitch changing process modulates the pitch of the time-aligned new signal to produce a time-aligned and pitch adjusted new signal.
