Looking at the spectrogram waveform display of https://freesound. Org/people/ivolipa/sounds/344948/ i noticed a few patterns. Distinct bands of high volume at around ~600hz, ~1200hz, ~1800hz, the fade in volume toward higher frequencies, a ubiquitous noise, and the soft staccato rhythm. Using these facts, i tried to make yet another engine sound with fm-synthesis. Sound forge 7 — to my knowledge — lacking a spectrogram, i've no clue if this was a successful attempt, but it does have a vaguely engine-like sound.
