Hey everyone, I onced asked for a analogue like noise but seemed had problem to connect to my schematic, can anyone give me a simple noise module with a knob for adjusting the noise levels ? yeah it would help to be analogue like... hope you can help me

There is a white noise generator and pink filter. To get stereo noise - just make two copies of that module (one to the left, other to the right) and give different seeds per module (like 2 and 3).

Check this.

Thank you, appriciated!

But how for example can I make this white noise generator feel and be like an analogue like noise ?

Noise is noise... the only difference is 'colour'- which is the spectral content.

I found this linklooking for samples of 'analog' noise generation and loaded the two 'versions' offered into FS and used the FFT analyser on them.

One is much 'pinker' than the other which seems very pure and (to my ear) indistinguishable from the generated version. The spectral content looks the same too... so maybe it's just a matter of some low-pass filtering to get a more 'analog' sound.

Here's what I used (can't leave the samples loaded as they're too large -- make sure you get the volumes balanced for by-ear comparisons).

By adding filters and some slight modulators on them. Plus maybe some dynamics. All depends on what you seek for in analog-like expression.
