Simple Stereotool Audio Processor
This is a Windows CLI script to process an audio track with a Stereotool preset and create a new video with the processed track as a replacement (or just a WAV/MP3 of the processed track).
The script needs FFMPEG (“ffmpeg.exe”) and Stereotool-Commandline (“stereo_tool_cmd.exe”) installed in the same folder or its binary folders included in the Windows PATH environment variable.
Download FFMPEG: https://www.ffmpeg.org/download.html
Download StereoTool command line: https://www.stereotool.com/download/
Example installation in a folder:

If you have a key for StereoTool, enter it in the script in the line
set stereotool_licence=""
at the beginning of the script (between the quotation marks, like <KEYVALUE>)
If you have your presets in a different folder installed than the folder where the script is copied to, enter the folder in the line
set "sts_folder=%~sdp0."
at the beginning of the script (replace “%~sdp0.” with the folder name, like “c:\my\stereotool\preset\folder”).
Just drag and drop one or more files onto the script
or place a link to it in the Send-To folder of your Windows (location: %APPDATA%\Microsoft\Windows\SendTo), select one or more files in the file explorer and run the script from the Send-To context menu option.
