Screen shot of K-Meter


Implementation of a K-System meter according to Bob Katz’ specifications.

K-Meter supports mono, stereo and 5.1 surround sound signals. All meters have been thoroughly validated. The average meter reads either RMS levels or ITU BS.1770-1 loudness weighted levels.


K-Meter was featured in an article by NPR Labs. Also, some users have reported that they use K-Meter for teaching, while others use it professionally such as in post-production.

I have merely added this section to show you that while K-Meter is free software, it delivers (at least) the same quality that you would expect from commercial software.

As K-Meter was coded using cross-platform code, it should be easy to compile a version for Mac OS X. Unfortunately, I happen to not have a Mac…

In case you want to help, please see the manual for ways to contact me. You’ll need sufficient experience in coding, compiling and debugging, though, so no beginners please!


The current version is 2.6.1 (built on 2016-10-07). The last version that will support Windows XP is 2.2.0.

I have recently moved to Windows 10. While the current version reportedly works on several Windows systems, some people seem to have trouble running it.

If you experience problems, you may use the older version 2.2.0 until I release a bug fix. To help me tracing the problem, please also report whether version 2.6.1 (especially the stereo stand-alone) runs on your system!

The manual is located in the subdirectory „kmeter/doc“, which also contains the release notes with information on changes and new features. The source code can be downloaded from GitHub.

Bug reports

Please report bugs using the K-Meter bug tracker. You may also use the bug tracker to place your wishes or ideas.


K-Meter is free software, and I’m not going to ask for money. Period.

In case you still want to show your gratitude, simply donate to a cause of your choice and tell me about it. Thanks!


This is free software and licensed under the GNU General Public License version 3 (GPLv3).

Please note, however, that the ASIO and VST SDKs are not free. I have used them because they are de facto standards that make life easier for musicians and engineers who just want to make some great sounding albums. Their licenses also do not interfere with creating free software.

But if you are a free software advocate, you might not want to use the VST plug-in. The pre-built GNU/Linux stand-alone and LV2 plug-ins really are free software in the sense of the Free Software Foundation. And you may build a Windows stand-alone that does not make use of the ASIO SDK. Hmmm, being a free software advocate, you probably haven’t heard of Windows, so forget about the last sentence… :)
