I've recorded an engine and I was look for some type of sample: the first (original record) with the engine in rev (throttle active). The second, the engine without adding throttle.
Some examples on YouTube
Throttle not active
I have what I need about active throttle phases, but I have nothing without throttle, so I ask if I can "remove" this mecanical sound or completly start an other track and generate a frequency similar in those videos (for example). Or maybe use this video for help me to indentify the frequencies to generate, I'm really disappointed with the audio development..
Here is one of my samples (mega.nz) "throttle active" with the mecanical sound.
