Abstract
An engine sound processing apparatus includes an engine sound signal generating section that generates an engine sound signal indicating an engine sound generated in an engine room of a vehicle, a signal processing section that includes a reverberation effect applying portion which applies a reverberation effect to the engine sound signal and a mixing portion which mixes the engine sound signal to which the reverberation effect is not applied and the engine sound signal to which the reverberation effect is applied, a reverberation effect controlling section that instructs the reverberation effect applying portion to apply the reverberation effect to the engine sound signal, a mixing balance setting section that sets a mixing balance in the mixing portion, and a speaker that outputs a sound on the basis of the engine sound signal being output from the signal processing section. In a case that both of an accelerator opening and an engine speed are increased, the mixing balance setting section controls an occupation rate of the second engine sound signal in the engine sound signal so as to be increased as the engine speed is increased. When other than the case, the mixing balance setting section controls the occupation rate of the second engine sound signal in the engine sound signal so as to become zero.
