US 2026/0171068 A1 · STEREO IMAGING ENGINE SOUND SYNTHESIS

Abstract

An engine sound synthesis generator system for a vehicle having an engine sound synthesis generator module executable by a processor to receive a signal indicative of an operating condition of the vehicle, receive a plurality of single-channel sound information signals representative of the operating conditions of the vehicle, apply stereo imaging to split the single-channel sound information signals into a multi-channel signals, and arrange the multi-channel signals into one or more sound signals to be played back at one or more loudspeakers in an audio system on the vehicle. A single instance of at least one audio effect may be applied to the multi-channel signals in aggregate. A gain may be applied to each of the multi-channel signals, individually or in aggregate, to amplify or attenuate the audio effect for each audio signal.

selecting a plurality of single-channel sound information signals from the sound library in response to the at least one operating condition of the vehicle;
converting one or more of the single-channel sound information signals into a multi-channel audio representation;
applying, using a single instance of an audio effect engine, at least one audio effect to the multi-channel audio representation in aggregate;
applying a gain to the at least one audio effect for one or more channels of the multi-channel audio representation;
mixing the multi-channel audio representation with at least one audio effect and the gain applied to generate a plurality of simulated sound signals;
and
outputting the plurality of simulated sound signals to a plurality of loudspeakers in the audio system of the vehicle.
