Identical names exist in the subfolders that bear the release/ tail of a wave profile because each must correspond to the corresponding main file when eventually played in the appropriate software. Those of you who may have processed sound files for jOrgan, GrandOrgue or Hauptwerk know what I am talking about.

Let's break your question into two parts: combining two 1-channel
audio files into one 2-channel audio file and scripting this
combination with multiple files in different directories.

There is one caveat: I don't have access to Windows 10, I'm using Windows 7.

1. Does this sox command work for combining two 1-channel files,
left.wav and right.wav, into one 2-channel audio file: stereo.wav?

sox -M -c 1 left.wav -c 1 right.wav stereo.wav



2. I would use a scripting language to work with multiple files in
different directories. Do you have Windows Script Host available on
your system?

a. Go to the command prompt. (Search for "Command Prompt" or "cmd.exe".)

b. At the command prompt, type this command:

cscript.exe

If the command returns an error, you don't have Windows Script Host
installed. If you do have it installed, let's see if you can create
and run a VBScript program. Type this command:

notepad hello.vbs

This will bring up the Notepad text editor for a VBScript program
called hello.vbs. Type the following text into Notepad, then save and
close it:

Wscript.Echo "Hello, World!"

To run the hello.vbs VBScript program, type the following command at
the command prompt:

cscript hello.vbs

The command prompt should display "Hello, World!". Let me know if
you're able to complete #1 and #2 to your satisfaction and I'll help
you combine the two to solve your problem.
