Voice Changer
The operating principle of a voice changer is to convert the analog signal to its digital version, and then through a digital signal processing system, add echoes or adjust the tempo and pitch of the voice to achieve the desired sound. The processed signal is then delivered to the DAC to produce an analog signal that can be outputted by the speakers.
