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.

Methods and systems for generating oscillatory timbres for musical synthesis through synchronous ring modulation are described. An example method performing hard synchronization comprising using first and second oscillators, the first oscillator being a fundamental oscillator which provides a fundamental frequency, the second oscillator being a modulation oscillator operable at a frequencies higher than the first oscillator; and in response to the fundamental oscillator completing its cycle, synchronizing the modulation oscillator to the original point of its waveform. Ring modulation may be performed on the synchronized output by multiplying it by a waveform of the fundamental oscillator, such that the ring modulation is synchronized to produce a variety of oscillatory timbres. The method can create a variety of unique sounds having musically pleasing characteristics. A real-time audio signal can be used instead of the first oscillator to produce dynamically varying timbres.
