question about the bass handling in nebula compressor

Post by dwagrimm » Wed Feb 19, 2014 10:12 am


I´m confused a little bit about the handling of signals with deep bass frequencies inside like Bass & Drum etc. in nebula compressors. I need some informations about that. I know the bass sound is in hardware compressors difficult too. you can hear some "overdrive / distortion" but in a good way. I even know the "distortion-limits" in nebula BUT some nebula libraries can handle that like the G2500 of gemini Audio or the 609A of cupwise can do that in a acceptable way. not perfect but practical and helpful. why can do that some libraries and some not? where is the problem? this is no criticism. thats a question. thanks for all informations.

An envelope detector is sometimes referred to as an envelope follower in musical environments. It is still used to detect the amplitude variations of an incoming signal to produce a control signal that resembles those variations.
Nebula use an envelope follower to translate incoming amplitude audio signal into a value that help to select the correct kernel that will process the incoming signal with the correct filter but this filter has a length that is more than one sample that is the reason that Nebula or any signal modeling processor can emulate correctly a peak limiter with out introduce audible distortion.
