Title: quickest way to compress amplitude?
Post by: p8rpp on September 19, 2019, 11:09:27 AM

Trying to find the quickest CDP command line way to compress dynamics (amplitude).

The only approach I have found so far is to extract the envelope from a time-domain sound
  ENVEL EXTRACT
and modify this envelope using
 ENVEL WARP COMPRESS
possibly post-processing it if necessary and imposing it on the original file,

It seems like a lot of steps necessary, is there a simpler/quicker way?

Thanks!

Hi,

Note that ENVEL RESHAPE uses an envfile as the input, but ENVEL WARP uses a soundfile as input -- i.e., the extraction is built in.  I don't see 'compress' in the list of functions -- which one did you use? Flatten? Gate? Limit? Ducked?  (or is it named differently in your version of the software?).

It's not something I've used, so look forward to other answers.

Thank you Archer, envel_warp looks like the program I was searching for!
