       convert4chan  - is a utility for converting pairs of stereo impulse response files to to a
       single 'True Stereo' 4-channel files.
       ir.lv2 - LV2 IR reverb plugin supports these so-called 'True Stereo' impulses.


       convert4chan /path/to/impulses/directory


       cd /path/to/impulses/directory and run convert4chan


       convert4chan is not itself a generally useful  program,  but  just  a  utility  with  very
       limited scope, Error checking is limited; you are not supposed to run convert4chan on your
       / .

       You can use it to convert a full directory tree of  stereo  impulse  response  files  with
       similar  names  that end with L.wav and R.wav to 'True Stereo' format, while your original
       files in directory stay untouched and can be later used as impulses as well.

       ´True Stereo' impulses are four channel impulses that describe a full  convolution  matrix
       (the four channels contain, in order, the convolution paths L->L, L->R, R->L, R->R).

       convert4chan searching for stereo files named:


       and convert them to:


       convert4chan  supports  filenames  ending  in  .wav  by design, but it is possible that in
       future will supports other audio formats too (It could  all  audio  formats  supported  by
       libsndfile in theory.)
