Kx soundkarten treiber - Wer kann mir bissle was erklären?

[Little Lamer]

Hi!
hab schon seit längerem diese KX treiber auf meiner audigy 2 (value). Ich komm auch soweit klar.
Aber im DSP gibt es ja ziemlich viele plugins wo ich mich frage was die überhaupt machen.
Ich kenn mich in den Sachen Hifi nicht so gut aus, lege aber dennoch wert auf guten Klang.

Was mich jetzt zum beispiel mal interessieren würde wäre was der "APS Compressor" macht und was die einzelnen einstellungen bedeuten ("attack time" z.b.).

Und jaaa ich weiss der treiber is eher für profis und nicht für so "anfänger" wie mich, aber mich interessiert das einfach und würde gerne das zeug lernen.


Gerne nehme ich auch links an. Über google hab ich nix brauchbares gefunden.

ich glaub ich versuchs mal im hifi forum.... :rolleyes:

ausprobieren ;)

im readme steht wies geht

aber brauchen tust du das nur wenn du musik machst, oder zum rumspielen

im wiki steht was ein compressor ist ;)
----------------------------------------------------
Compression parameters

The following parameters are commonly found on compressors.
Threshold

The threshold is a value at which the compressor starts to become active. For instance consider a signal that is between 0 and 10. If a threshold is set to 5 then when the input signal is below 5 no compression will occur. When the signal goes above 5 the compressor will kick in and start to compress.
Ratio

The ratio determines the amount of compression that will be done. It is defined by the level of input change to output change. for instance the ratio 5:1 will mean that for a level increase in the input signal of 5 will result in level increase in the output signal of 1.

It should be noted that if a ratio is less than 1:1 then expansion will occur. see expander
Make up gain

This is often performed after compression occurs. It controls a gain increase that is uniformally applied across the output signal. After compression the maximum value of a signal could be less than before, giving you more headroom?. The make up gain allows you then to raise the entire signal to make use of this extra headroom?.
Attack time

This parameter detemines when the compressor kicks in after the signal has reached the threshold. By having a slow attack time you will allow for some of the snap from the input signal to be unaffected. Consider the following phrase
be BOP DE BOP BOP

a slow attack time would create the following
be BOP DE BOP BOP

where as a fast attack time would create the following
be BOP DE BOP BOP
Release time

Release time determines how long the compression will remain in affect after the input signal has dropped below the ratio. Again consider the following phrase
BE BOP DE BOP BOP

with a slow release time the following will occur
BE BOP de boP BOP

where as fast release time the following will occur
BE BOP DE BOP BOP

Clever use of both release time and attack time allows you to create more headroom yet still keep the percieved dynamic range the same.
knee type

The knee determines what happens when a signal is around the threshold. You will often hear the knee being refered to in the terms of softness (hard or soft). If a hard knee is applied then the threshold is strictly obeyed. Whereas a softer knee means that at values around (both above and below) the threshold some amount of compression at a ratio less than the defined ratio will be performed.

This is easier to explain with a graph? does someone else want to have a go!
