Did you know REAPER includes over 250 audio effects? JS Effect Spotlight is a series of articles highlighting the often overlooked JS effects included with REAPER.
The Soft_Clipper effect written by Shwa is another hidden gem in the JS effects bundle and one I use a lot in mixing rock music.
A soft clipper takes the loudest peaks and rounds them off. Often this is a more effective way of increasing loudness than a brickwall limiter, it doesn’t pump!
Pushing it hard can cause distortion but when clipping off a couple dB either on a master or individual tracks it can be very transparent.
The JS soft_clipper has only two controls:
Boost increases the input up to 9dB
Output brickwall is the ceiling or absolute max output level which can be set from -3 and +1 dBFS
You can use this on your master bus either before or in place of a brickwall limiter. I find it very useful on kick and snare tracks where I need them to be loud but not actually take up headroom.

My favorite JSFX is LOSER’s Zero Crossings Maximizer. I use it on every project. Another good JSFX is the tonegenerator. Useful tool.
Nice idea to speak about JS effects. There are so many and I don’t know them enough.
I like hq9000/multifreaq as a spectrum analyzer,
3BandSplitter and 3bandJoiner to dome some multiband processing (no phase issues, sounds perfectly)
Those 3 I’ve never knew about, exactly why I started this series. Thanks for the comment.
I often use 50HzKicker or HugeBooty for enhancing kick drums if it’s absolutely necessary, floaty delay, and the 1175 compressor. I also really like the Compciter on snare.
even more JS plugins I haven’t tried. Adding these to the list.
Great tipp, it’s still a big mystery with these JS plugins, but so far great hints. I kinda like the sound from Soft Clipper. Thanks
Thanks! Worked great for my handclaps.
