Hi!

I know that sounds very simply
but how can i synthesize the crack of a vinyl?
only the crack, not in combination with other sounds.

i tried it with different filters but i dont find the right combo.

I hope you can help and the question is not unnecessary.

thanks a lot

you can emulate vynil cracks on Reason using the Noise Oscillator on the thor synthesizer using static and sending random note on messages to the gate, it sounds a lot like vynil cracks if you want i can send you a combinator patch.

i havent tried to emulate this on PD...

Some thing like this gives decent results:

[noise~]
|
[expr~ pow($v1, 4000)]

simple&beautiful,
thank you Maelstorm
It'd be nice to add a switch with 78, 45 and 33 rpm fx

simple solution,
simple answer:

that is the tone, which I can process on
thanks

@ Maelstorm:
care to elaborate on what's actually going on there? seems real simple but i can't wrap my head around it. [noise~] is generating a random audio signal from -1 to 1 right? so what's the pow($v1, 4000) doing exactly, and why 4000?

Every time a number between 0 and 1 is multiplied by itself, it gets smaller. And the smaller the number is to begin with, the smaller it gets. This also means that numbers closer to 1 don't get reduced that much. By multiplying it by itself 4000 times, most of the noise gets nearly inaudible and only a few peaks remain, which become the crackles. 4000 just seemed to be about when it started to sound like a record crackling to me. It's probably worth playing around with that number. Actually, it probably makes more sense to make it an odd number to keep it biased around DC (even powers result in negative input giving positive output).

I think a higher exponent is more effective!

or

[noise~] [ more crackling
| /
[lop~ 100]
|
[cos~]
|
[clip~ -0.5 0.5]

produces also nice sounds. ///
