Abstract
This paper presents a new method for modeling and synthesis of
automotive engine sounds using a deterministic-stochastic signal
decomposition approach. First, the deterministic component is extracted
using a synchronous discrete Fourier transform method and this is
subtracted out from the original signal. Next, the (residual) stochastic
component is modeled (and synthesized) using a new multipulse excited
time-series modeling technique. The effectiveness of the proposed
methodology is demonstrated using recorded data sets of actual engine
sounds. The results of both numerical and subjective assessment tests
are presented
