    Need help for scifi engine sound


    The kind of sound I'm talking about can be heard in this clip:
    http://www.youtube.com/watch?v=m8r2qsNVF7w
    It's the stuttering engine sound the left craft makes at 0:21 when it banks and flies off the screen.

    What do you call this kind of effect and how do I recreate it?

    Hello, I can not see teh video you posted but I have put together some generator sounds from fridges, ari-conditions and sine waves.

    You are welcome to check them out.

    There's a spurious ; in the OP's link, it does that to me too if I try to paste the correct link in this message.

    take your base-level signal and modulate it; i.e., multiply it by another that is offset so that the values range between 0 and 1 (instead of -1 and 1). The modulation signal should be low, like around 4 to 9 Hz. Maybe a cross between saw-tooth (downward) and triangle.

    Sorry about the broken link, fixed it now.

    avakas: You got some really great sounds there, but it is not exactly what I'm looking for.

    The sound I'm referring to in the video is very distinctive, I'm sure you will recognize it when you hear it.

    I will try your technique zimbot, sounds interesting.

    Thanks for the fast replies!

    chopped / chopper ? ... http://www.freesound.org/people/Timbre/sounds/95895/
    i.e. noise amplitude-modulated with a low frequency rectangular waveform (e.g. square wave)

    there is a doppler [pitch] shift too.

    Thanks Timbre! Just what I was looking for.

    Got the basics down for it now, modulating the amplitude/pitch of engine and hum sounds with different waveforms can produce some really cool results.
