This should be the last update before the official release, well, I hope so. 😁

This update mainly improved the stability of the meter. I have fixed some crashes; hopefully, they won’t pop up this time.

In case you missed the latest BETA update announcements, you can read them by clicking on the links below:

V2.5.0 BETA – Announcement

V2.5.3 BETA – Announcement

Changed BETA label

Let’s start with the most critical change you’ve requested. The beta label will now include your license type as well. Here’s how it looks:


Old Look:

New Look:

Now seriously, some of you had some confusion about the license so I changed that, but you must admit, it is a pretty nice feature. 😁

Added more channel configurations

Oh, this was a tough one! 😰

Up to 5.1 channel configuration, situation is kinda OK, but once you go to 7.1 and up, it starts to be really messy.

There are a gazillion versions of how channel names and channel orders are handled. Why can’t our industry just agree on how 7.1.2 channel orders and names are handled?! 😠

Anyway, 40 papers and links later, I managed to make a list with channel configurations that this version will support. If you feel some channel configuration is missing, please let me know. 👍

In this version, you will have 49 new channel configuration options.

The meter will now support these channel combinations: 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16, and 24 channel audio.

What’s really cool is that plugins will now have an auto channel configuration selection feature. That means that the plugin will detect the bus channel configuration and it will automatically select the correct one.

This works in most major DAWs that people usually use to work with multichannel audio like Nuendo, Pro Tools, Logic Pro X, etc. If this is not supported by DAW, the plugin will use the stereo channel configuration by default.

BTW, all possible channel configurations should be supported in Pro Tools, Nuendo, and Logic Pro X.

  • Pro Tools supports up to 9.1.6
  • Nuendo supports up to 22.2
  • Logic Pro X supports up to 7.1.4

Here’s how this looks in practice:

The (A) will indicate that the channel configuration was automatically found. If you don’t see it, you will have to manually select the configuration.

This is such a time saver and helps prevent user errors such as selecting the wrong channel configuration, so I am super excited about it. 😄

Normalize will write BWF metadata

I have added an option to add BWF loudness metadata to the normalized file.

Here’s how it looks:

Multi mono normalization improvemenets

If you normalize multi-mono files, the normalization will produce the multi-mono files back. You can also force multi-mono output for multi-channel files.

Copy measurements summary to clipboard

Since we already have a text summary export option, I thought it would be nice if you could copy the summary of current measurements to the clipboard.

You can now do this by clicking on this button:

You will then get this copied to the clipboard:

Auto resizable peak meters

Believe it, or not, this was hard to implement and I wasn’t excited to work on it, but this was the top feature request from the previous beta version, so here it is. 😎

Meter bars will resize based on the channel configuration selected.

Here are a couple of examples:

You must admit, the 22.2 channel configuration does look a bit ridiculous, doesn’t it? 😂

You have the option to select automatic resizing, but you can also set the meter to have a fixed number of channels shown. This can be particularly handy if you are not sure how many inputs you have and you want to monitor all channels at once.

Here’s how you can set that up:

For example, if you set the meter to always display 10 channels, this is how it will look:

Updated window scaling

Some of you had a problem where the meter interface appeared super small, so I took a look at the code and found that some stuff can be improved there.

There was a bug that caused window scaling to reset to the minimum on macOS, which should now be fixed with this update. Also, I took the opportunity to update the Windows scaling. The meter now supports per-monitor window scaling in DAWs that support it. I’ve also added support for HiDPI for some DAWs that require the plugin to explicitly signal its HiDPI compatibility. Hopefully, plugins will now always open in HiDPI.

Here’s a look at how it appears in Bitwig with 150% Windows scaling:

It’s finally clean.

The only downside with this update is that window scaling will be reset to default, but you can always change it in the view settings:

The final BETA

I know that I am boring with these BETAs, but it was important to test these updates publicly as there were so many changes added to the meter.

I’m hoping this will be the last beta update. No more new features until I release a stable one. 😄

Please let me know what you think, and let me know how window scaling and channel configurations work for you.
