Apologies, bad terminology on my part, Doppler PITCH shift I should have said. Not sure inwhat situation Phase shift would occur.
There are other issues with the current sound engine that the previous one didn't have. The Current engine seems to use a very aggressive compression filter. The impact of which leaves the Sonic boom sounding like a wet fart compared to Lomac's Room shaking version, both use the same sample. There is no dynamic range left in the sounds as the current engine strains to play everything at 11 and then limits them at 10 (Not literally BTW).
