Infact English people could recognize a 109 from a Merlin engined airplane simply hearing the sound emetted fomr the engine: the 109's sound wasn't linear, but was a highrev sound followed by a lowrev sound, while the spitfire sound was quite constant.

What's your source for this information ?
Don't confuse the
drone of the bombers which was different for Axis and Allieds, the German bombers would sound like they were pitching up and down due to unsynchronized engines.
My house was on the WW2 German bombing flight path and the flak enplacement at the end of my road (London) was active at
night and the listening stations along with radar would identify the enemy, locally by sound then confirmed to fire barrage flak.
Some of my neighbours have lived here since the war and are useful for local history etc.
