    摘要: 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.

    摘要: The most appropriate data of a plurality of level-converted digital data, obtained by level conversion of the input digital data by different conversion factors, is selected based on a signal quality of each of the level converted digital data. The other data of the level-converted digital data is attenuated to or below a predetermined noise level. Switching between previously selected data and newly selected data is effected by cross-fading. The level-converted digital data are D/A converted to respective analog signals.

    摘要: In a sound image creating apparatus, a distance computation section computes intermediate positions of a moving point along a trajectory line from a movement start position to a movement end position, and further computes a variable distance between each of the intermediate positions of the moving point and a fixed point. A velocity computation section computes a variable velocity of the moving point relative to the fixed point along the time axis on the basis of the variable distance. A signal processing section attenuates or delays an input sound signal in accordance with the variable distance, and varies a pitch of the input sound signal on the basis of the variable velocity, thereby creating the sound image of the input sound signal along the time axis based on principle of Doppler effect.
