1. A method for generating a vehicle sound at a modified pitch for a range of vehicle engine speeds, the method comprising:
receiving a range of engine speed transition;
dividing the range of engine speed transition into a plurality of intermediate speed regions; and
for each speed region of the plurality of intermediate speed regions, identifying a representative segment of a sample sound based on the pitch of the segment;
re-segmenting the representative segments of the sample sound; and
overlapping and adding the representative segments of the sample sound in a pitch synchronous manner to an audio output.
