Abstract:
Examples of the disclosure describe systems and methods for presenting an audio signal to a user of a wearable head device. According to an example method, a first input audio signal is received. The first input audio signal is processed to generate a first output audio signal. The first output audio signal is presented via one or more speakers associated with the wearable head device. Processing the first input audio signal comprises applying a pre-emphasis filter to the first input audio signal; adjusting a gain of the first input audio signal; and applying a de-emphasis filter to the first audio signal. Applying the pre-emphasis filter to the first input audio signal comprises attenuating a low frequency component of the first input audio signal. Applying the de-emphasis filter to the first input audio signal comprises attenuating a high frequency component of the first input audio signal.
