Can someone tell me how to sample Compressor?

Postby tunca » Sat Dec 01, 2012 1:38 pm

Hi,

I read NAT tips 23-24 about sampling compressor but i don't understand :roll: Maybe i'm idiot.I don't know..

But someone can tell how to sample compressor step by step i can understand.If i understand,i will sample Behringer V-amp 2 compressor for example.If i do it good,i will sample LA-2A clone.

Please tell me step by step. :cry:

Thanks!

From my experience, there isn't a step-by-step that will work. At least not work PERFECTLY for EVERY compressor. In the little bit of experimenting I've done, it was really about changing numbers/settings just to see/hear what they did.

Start doing that and believe me, you'll start learning. It's becoming apparent to me that NAT isn't a destination, it's a journey!

I'm trying to sample offline VST compressor to learning sampling compressor.I'm using threshold,attack,release and ratio parameters.And i have 4 .wav sound.I'm rendering all.But which .wav that i will deconvolve? I have problems about it :roll:

I'm still trying to understand.

I'm using Reaper and i try to sample ReaComp.Settings are fixed.Ratio 30:1 , Attack 10ms , Release 100ms and Threshold 0 to -40.I wrote all parameters.And i generate tone.When i generate,i get Instructions.txt.And it's like this;

comp_R0_T0.wav <- Rati(1.00 -) Thre(0.00 dB)
comp_R0_T1.wav <- Rati(1.00 -) Thre(-40.00 dB)

comp_EA_A0.wav <- Atta(1.00 ms)

comp_ER_R0.wav <- Rele(0.10 s)

I render .wavs with name and settings like Instructions.txt.

And the PROBLEM!

Which sample that i deconvolve? :roll:

Or what i missing? :shock:

Sampling a compressor is a 3 dimension sampling. You will have the VTT (Volterra test tone), I/O, Attack and Release.

EA = Attack
ER = Release

Thanks.

When i use EA and ER,what will be threshold and ratio settings?

And which sample that i use to deconvoling?

I don't understand anything from sampling compressor topics. :oops:

Can you tell clear?

By the way when i generate test tone,i get 3 .wavs

testcomp ; 30 mb
testcomp_EA ; 1.3 mb
testcomp_ER ; 4.8 mb

I think .wavs are too small?

And what will be threshold TYPE? AU like ratio?

One is to model the gain-reduction, one the envelope of the attack, and the last to sample the character of the release.

testcomp_ER ; 4.8 mb


The attack and release are smaller files because they are shorter. You sample the gain-reduction MANY times to get the sound more accurate between dynamic steps (in addition to using a longer sweep tone, in theory).

Set the threshold so that the LAST dynamic step is left uncompressed. Ratio is sampled as a separate parameter.
