This is the script, and it’s made for Reaper – and its “JS” language.

It processes stereo audio.

Is there a way to translate this into MaxMSP?

Long answer: In order to do this with scripting, you would have to know some things about scripting MSP objects in js. You would then have to figure out what objects to use in a normal Max patch to replace the reaper objects, and then link the patcher objects to scripting variables. Then you could begin to translate the reaper js script to Max js. This is not a straight forward process, and you would for all purposes be rewriting the entire thing in a new language….there is no direct (or even general) translation from one js to the other….its only coincidental that both Reaper and Max support js, so you could do this, but probably not like you are thinking….hope that makes sense.

the language is simple and described here:

http://www.cockos.com/reaper/sdk/js/js.php

to translate a text based language to a max patch is not trivial, but one basic principle is the assignment operator (=) is like a patch cord, and the expression on the left is like the input object, and the expression an the right is like the signal output object.

some of the code is done on a sample-by-sample basis (not block or vector) so you’d need to interpret that code in terms of what it’s intended function is
ie this fragment:

xLP = exp(-2.0*$pi*freqLP/srate);
a0LP = 1.0-xLP;
b1LP = -xLP;

is setting up coefficients for a filter, so you’d need to figure out what the filter is and then find the max equivalent (maybe [onepole]?)

So if you understand DSP techniques, then this code would be fairly simple to translate. If not you need to learn a bit of filter theory and also read up on the JS syntax.
