another FREE tool that sums 2 Split Mono WAV files to Stereo Interleaved for PC.

sums 2 dual split mono .L.wav and .R.wav files by Mashing them into one Interleaved Stereo file.


Anyone coming from Pro Tools land should be able to use this program to combine .L/.R files into one.
NOTE: Masher does not convert from SD2 files and only works on WAV and BWAV files.

If your files were converted from SDII to BWAV in a program like Nuendo your files might look like this:

SI6005-Car Crash
SI6005-Car Crash-01


SI7000-Metal HitL-06
SI7000-Metal HitR-07

Masher looks for files with the same name minus the last 4 characters.  If they have the same NAME/LENGTH/SIZE then it assumes the ‘-01’ file is the right side of the file and mashes them together.

It will then rename the original files with ‘.old’ extension or deletes the original depending on which option you choose.  Masher also Ignores .L and .R in the file names even if they appear in the middle, so if your files are named

SI6005 .L Car Crash
SI6005 .R Car Crash

it will also consider these a match as long as length and size match.




Backup your data First!

We are NOT responsible for mowing down your library of sounds.  Also, do a few test folders first to see how it works before you run it on your whole library.

For best results use a batch renamer to remove all NON-ASCII characters first like REHAB.  Fortunately for you, included in the package is a program called Cleaner.
That is exactly what Cleaner does.   It removes all illegal characters that some PC’s can’t read.  Just run it and select the directory to Clean.  Cleaner has no progress bar so wait a bit before you start mashing.  It runs in the background very quickly and looks like it just quit, but it is working.
