Abstract
Synthesizing engine sound in a cabin of a vehicle includes generating a synthesized engine noise audio signal including a plurality of engine order outputs; mixing the engine order outputs in accordance with a first set of gain levels to provide a first channel output; mixing the engine order outputs in accordance with a second set of gain levels to provide a second channel output; using a first localization filter set to provide a first localized output to localize the first channel output as a first sound image at a first location within the cabin, and a second localization filter set to provide a second localized output to localize the second channel output as a second sound image at a second location within the cabin; and mixing the first and second localized outputs into loudspeaker outputs to be applied to the loudspeakers in the cabin.
