Mute, Change, and Boost PC Volume Instantly with SoundVolumeCommandLine

SoundVolumeCommandLine (svcl.exe) is a powerful console application developed by NirSoft that lets you manage Windows audio levels directly from the command line. It is the lightweight, console-only counterpart to the graphical tool SoundVolumeView. Because it lacks a user interface, it is highly optimized for integration into automation scripts, batch files, and scheduled tasks.

You can download the tool from the official NirSoft SoundVolumeCommandLine page. Core Parameters Syntax

When executing commands, you must target specific elements using an Item ID or Name.

Target Types: You can target a system device (e.g., Speakers, Microphone) or a running application (e.g., chrome.exe, spotify.exe).

System Requirements: Works natively on Windows Vista up to Windows 11 (both 32-bit and 64-bit systems).

Outputting Data (/Stdout): This parameter is unique to svcl.exe. It sends the results or status information of your executed audio command directly to the console stream instead of a file.

Getting Audio Status: To capture the current volume level inside an automation script, you can query the system and read the application’s exit code (%errorlevel%): svcl.exe /GetPercent Speakers echo %errorlevel% Use code with caution.
