Engine Sound Algorithm

[keiranval]

Hi All,
I'm sending this message to two groups that might possibly have leads
on algorithm research to convey convincing vehicle engine sounds. I'm
currently using the tried and true layered/crossfade sample approach,
but it isn't entirely convincing. I've heard from a couple of people
at AES yesterday that granular synthesis was experimented with but
abandoned for the crossfade sample method. I don't know why, and it
would be great to understand why or if others have experimented with
other ideas.
