How do I make the sounds from
from 0 to 13 seconds.More specifically the ambiant voice like sounds, the percussion and also the kind of filter sweep going on.
The voice is produced by using reverb-freeze, or reverb on a short vocal extract with full sustain. This is then fed to a channel which is gradually faded in.
The filter is first a high-pass filter gradually increasing the threshold, then cross-fades fast into the same sound but on a low-pass filter. Or as this is highly likely using automation channels the filter cut-off type is just switched and the threshold value set to almost bottom again.
