The present invention relates to a headphone amplifier for calibrating the frequency deviation of a sound source. The amplifier uses sampling rate information to input a frequency switching control parameter output by a mode controller to a LUT. Simultaneously, the sliding mode filter is controlled to operate in a fast frequency switching mode. The filtered control data is sent to a low-noise DAC, passed through an analog loop filter, and then output to a VCO. The VCO output is sent to a synchronous frequency divider and then to a frequency measuring device consisting of a counting window generator and a counter to complete the frequency measurement. The frequency measurement result is sent to the LUT and the mode controller, which controls the loop. 20kHz audio is superimposed on the input sound source. After the superimposed audio is loaded, it is processed together with the original audio. The processed audio is then passed through an amplifier and detected by a detection module. The frequency offset, broadening, and loudness changes caused by the processing can be fully detected, thereby displaying the operating status in real time on a display module, allowing users to understand the device's operating status at all times.
