Hello Sox Users Mailing List, Finding the documentation for the „compand“ effect as very difficult and hard to interpret I decided to post here the settings I used. Soft Limiter: @-12db compand 0.01,0.1 6:-12,-12,0,-10,0,0 0 -90 0.01 Hard Limiter: @-4db compand 0,0 -4,-4,0,-4,0,0 0 -90 0 Regain: gain -n -0.1 It is suitable to use these three effects in a chain. I have left the last transfer point (0,0) that is usually omitted for clarity. It may be removed without charge to the function. The Soft Limiter has three points: (-12,-12): It will not touch any value lower than -12db. (0,-10): Any value between 0db and -12db will be compressed to -10db, with a soft knee of 6db: this means that at -6db the compressor turned on 100%. (-12db + 6db). (0,0): default value, no change if omitted. The fast attack time of 0.01 is set the same as the delay. Release is longer 0.1. The Hard Limiter also has three points: (-4,-4): Any value less than -4db is not touched. (-0,-4): Any value between 0db and -4db is limited completely to -4db. (0,0): Default value, no change if omitted. The attack and release, and delay time is 0, meaning the limiter acts instantly. I hope that this helps some people. If I have any mistakes in my interpretation, please say so. Cameron. _______________________________________________ Sox-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/sox-users
