Abstract
A vocal mix circuit shifts the phase of a mixed audio signal using a phase shifter, and achieves a mixed signal emphasizing the voice components thereof, by subtracting a signal which is not shifted from the signal shifted by the phase shifter. Gain through the above steps is controlled by the gain controller. Then, operators process both the initial signals and the signal through the phase shifter and the gain controller. Accordingly, the vocal mix circuit enables a person to hear with high sensitivity, has a simple circuit, and reduces the number of external pins.
