D/A conversion device, method, storage medium, electronic musical instrument, and information processing apparatus

A digital-to-analog conversion method for a digital-to-analog conversion device comprising circuitry including an integrator, a first quantizer, and an output section, the method comprising:

• performing, by the integrator, integration processing for integrating a difference between an input signal and a first return signal and a second return signal generated based on the input signal, to thereby generate an integration result;
• performing, by the first quantizer, first quantization processing for quantizing the integration result generated by the integrator, to thereby generate a first quantization signal;
• and
• performing, by the output section, output processing for outputting output signals including a Pulse Width Modulation (PWM) signal whose pulse width is asymmetrical to a center of a processing period, based on a first quantization signal generated by the quantization of the first quantization processing,
• wherein the first return signal delays the first quantization signal,
• wherein the second return signal delays a correction value signal outputted based on the integration result generated by the integrator, and
• wherein the correction value signal includes a signal indicating a correction value for correcting a difference between (i) a center of the pulse width asymmetrical to the center of the processing period and (ii) the center of the processing period.
