    Creating a vehicle engine loop?


    Hey guys. Just looking for a bit of help/opinion! smile

    My question is hopefully simple, but here's my background info: I'm recutting the audio to a trailer for Need For Speed as practice to audio design. It's about a minute and a half clip of two racers barreling through a city with two police cars in pursuit. Obviously, I want the engines to have a certain character - each one should sound somewhat different. I want the cop cars to have somewhat of a clunkier, heavier sound - I'm thinking of diesel engines and maybe pitch shifting that up a little bit, or recording my buick revving through the paces a little bit. As for the racing cars, I want to give them a waspier sound. In my library, there's a few stock sounds for Porche's, NASCAR stock cars, etc etc. Generally, my idea for audio for tthe main "character" cars is something that I don't have access to record. I've basically got a few idle-engine loops and "passby" clips to work with.

    My questions are:

    1) If I go the route of recording the buick, where would be a good mic placement? I'm assuming I could just open the hood, put it in neutral, and have someone control the acceleration? Is that a decent idea?

    2) For those "waspier" cars, how could I go about turning an idle loop into a more realistic sound of a car driving at upwards of 60mph? Is there any good way of editing the sound files to get that? I'm really not much of a gear-head so I don't actually know what those will sound like outside of some low-res youtube clips.

    3) How would I go about getting the sound of a good downshift or upshift? As I understand it (and I might not at all) car's don't actually shift up or down in neutral, right? So is there a way to emulate that?

    Sorry if these questions are basic - I'm still going to go ahead and tinker around with getting this to sound good. Just curious of the approach some of you with more skill/experience might have! smile

    Thanks in advance!

    editing cars is tricky to master.

    you may have to cheat sometimes.. from experience yes you can use the sound of a stationary car's engine revving... or holding a steady higher rev - or a slowly rising rev might also work...

    you then add passing effects and wind movements to simulate movement - think if u drive a car down a street - the sound it makes as it swooshes past individual objects...

    more effective if the shots are short...

    idle loop to waspier? not sure how this is possible... you need to record.. or maybe get hold of the library 'wheels' theres a BMW maneuvering on there I think.. ( sound dogs may have a preview wink )

    ( i did place a 'skyline' up here somewhere.. and also a car skid from a scene in a movie I did location sound on ( running out of time - with andy lau ) I can place some more if I get time to did thru..

    u will also need to record some of your cars moving to get the shift effct... but do u want interanl or external sound.... I found u can fake both from either - and recording internal is easier to do..

    also if u have a nice car approach *sometimes* u can use it in in reverse ( ie if a car accelerates up - try reversing the soud file... and voila the care is now going away ... - it may well work sometimes if there is not to much dirt on the recording or reverberations.. ...

    it wont sound like a car reversing... that sound is the reverse gear whining....
