1. A method for generating an audio signal, the method comprising:
receiving a first signal associated with a voice input;
receiving a second signal associated with an audio input;
separating the first signal into a first low frequency signal and a first middle frequency signal;
separating the second signal into a second low frequency signal and a second middle frequency signal;
adjusting an amplitude associated with the second middle frequency signal by:
generating a combined gain value based on applying a first gain value to an amplitude associated with the first low frequency signal and applying a second gain value to an amplitude associated with the first middle frequency signal, and
applying the combined gain value to the second middle frequency signal to generate an adjusted middle frequency signal;
combining the first signal with the adjusted middle frequency signal and the second low frequency signal to generate a combined signal; and
causing an output device to output the combined signal.
