Can somebody tell me what effect/processor I need to apply to make any sample "stutter" like this chainsaw in this trailer @ 0:58

I'm using Cubase and Sound Forge, so if your answer could be related to either. Even better! Thank you.

You could either:

1, manually automate the level like a square wave

2, use a tremolo plugin set to square wave and automate the mix control

3, insert a copy of the sample into a sampler and punch in 16/32nd notes with slight gaps (turn release down to 0)

4, chop small sections out of the clip.

There's a few alternatives, but they are usually plugins

It sounds like there's distortion or a white noise generator mixed, so perhaps try using a separate effect track (sample copy).

  • The theory makes sense. Just need to try it try it. Thanks.

Assuming you have a chain saw. Record it with a tap delay configured for short bursts.

  • The effect is for any given sample. I don't particular need the chainsaw sample. I'm trying to produce Dubstep and I hear this effect a lot, so I would like the ability to reproduce it to any given sample that is already recorded. Thank you for your input all the same.

Perhaps this technique will be of value to you:

[Anything to get more good dubstep out there]

Listen to that clip again and notice the following things:

  1. The effect is created primarily by playing a continuous sound and then modifying it
  2. The modification starts suddenly and last the duration of the original sound (presumably)
  3. The modification to the sound, it'self changes:
  4. It starts by rapidly breaking up the original, and on each pulse becomes less rapid.
  5. It originally breaks up the original into brief bursts, but the burst become somewhat longer. (This is not the same as 4 - which is the space between bursts)

In order to achieve this effect, you are going to need at least two Low Frequency Oscillators (Plus these are the bread and butter of any dubstep master) and some form of modifier on the original sound.

It sounds to me as if the original is driven (after re-verb and probably resonance filters) through a compressor limiter. I suspect that the compressor's gate is driven by an LFO (which is itself driven by a second LFO).

You could probably achieve a very similar result by sending an original sound via a Frequency-Resonance filter, and just run the LFO chains on the Frequency dial.

I managed to create this effect (well similar for the most part) in Reason as in the picture below:

Except instead of routing the LFO's to the compressor (it was quicker) I just routed them to the Amplitude of the Synth it'self.

[Hours of fun!]

Let me know how it turned out for you.
