stupid looping sound

[billowillo]

well im trying to make some sounds for my game but theres a problem... ok ill start from the begining. So i made a engine sound for my car in the game but when it loops it makes this realy bad off key sound

this is a bad example but i dont have much time http://www.4shared.com/file/32474795/4a ... ample.html

so im asking how can i remove this or cover it up so it doesnt sound so bad and offkey?

That doesn't sound like it's just a loop playing - the pitch is changing.

The usual problem that people have with loops are a) the end and begining of the loop do not match. and b) the sample is too short so that the rapid repeating creates a low tone that modulates with the original waveform.

Hmmm, I am gonna say its problem "A" what is a simple solution to this?

I've just had a quick look on Google for a tutorial for you, but not found much.

You could have a look at the "Looping" section in this article - The article is about using some other software, but the general points about choosing loop positions will hopefully give you some ideas.

Oh one other thing - don't use mp3's for looping, it doesn't work because mp3's always add a bit of silence at the end of the file, which messes up loops - use wav files instead.
