Midside Matrix is the utilitarian younger sibling of Midside, our full-featured, mastering-grade mid/side processor. Midside Matrix accomplishes the essential mid/side processing & conversion tasks in a simple, lightweight package — and it’s FREE!

Background

To read more about the concepts of Mid/side audio, please see the Background section of the Midside manual.

  • Want to enhance the width and size of the chorus in your mix? Try automating up the Side Gain when the chorus hits.
  • Want a bridge section to feel smaller and more compact? Automate the Side Gain down.
  • Want to turn your favorite stereo analog compressor into a mid/side-capable compressor? Use Midside Matrix to encode a stereo signal as M/S to feed the compressor, and another instance Midside Matrix to decode it post-compression.

Visualization

Goniometer

Midside Matrix includes a large real-time stereo display called a goniometer (or vectorscope). By interpreting the goniometer, it’s possible to quickly deduce many characteristics about the stereo field and the precise relationship between left & right channels.

Here are some examples of how simple stereo signals appear in the goniometer:

Controls

Primary Controls

Mid

Mid On/Off

Turns the mid signal On and Off.

  • Min Off
  • Max On

Mid Gain

Adjusts the gain of the mid signal.

Mid Gain includes a level meter embedded in the slider. This meter shows the peak level of the mid signal both pre (lighter color) and post (darker color) Midside Matrix’s processing.

If the signal peak exceeds or equals 0.0dB the meter color turns red, indicating that clipping could occur. Midside Matrix will never clip internally, due to its double-precision floating-point processing, but the signal might be clipped at a later stage (by the host/DAW or DAC).

  • Min -96dB
  • Max 12dB
  • Default 0dB

Side

Side On/Off

Turns the side signal On and Off.

  • Min Off
  • Max On

Side Gain

Adjusts the gain of the side signal.

Side Gain includes a level meter embedded in the slider. This meter shows the peak level of the mid signal both pre (lighter color) and post (darker color) Midside Matrix’s processing.

If the signal peak exceeds or equals 0.0dB the meter color turns red, indicating that clipping could occur. Midside Matrix will never clip internally, due to its double-precision floating-point processing, but the signal might be clipped at a later stage (by the host/DAW or DAC).

  • Min -96dB
  • Max 12dB
  • Default 0dB

Input Mode

Sets the input signal format.

Output Mode

Sets the output signal format.

Flip L/R

Swaps the left and right channels.

About Goodhertz Plugins

User Interface

Goodhertz plugins are made to be workhorse tools that sound amazing. We’ve put a lot of thought and care into the audio quality and plugin usability, and for that reason, we’ve opted for simple and direct controls & interfaces that don’t rely on photorealistic knobs or ornamental screw heads to communicate their meaning.

We’ve also decided to only include meters and graphs when we feel they will directly lead to a better sonic result. Meters/graphs can consume significant CPU resources, and we firmly believe that if it sounds good, it is good.

Our meters can be manually enabled or disabled via the “Enable Metering” User Preference.

Keyboard Shortcuts

ActionKeyboard Shortcut
Enter New Parameter ValueOnce you’re tapped or double-tapped a control, type in a value, then hit Enter, Return, or Tab
Increment Parameter Value or arrow keys
Decrement Parameter Value or arrow keys
Jump to Next ParameterTab
Jump to Previous ParameterShift + Tab or ` (backtick)
Escape Parameter Focus / Close any Open DrawersEsc
Toggle A/BA (N.B. For this to work, you must have a control selected.)
Shift A to B / Shift B to AShift + A — this “shifts” the current settings to the opposite A/B state; i.e. if you’re on the A state, hitting Shift+A will copy those settings to the B state. (N.B. For this to work, you must have a control selected.)

Right-Click Preferences

ActionExplanation
Always Open Advanced PaneBy default, this is false — i.e. when the plugins open, they do not show you the advanced controls available by hitting the ••• button in the sidebar. If you’d like to always see the advanced controls, enable this preference.
Enable MeteringBy default, this is true — i.e. in normal operation, all audio meters and visualizations available in Goodhertz plugins are enabled and running. If you’d like to turn them off and disable all metering and visualization, deselect this option. And to turn them back on, simply reselect it. N.B. If you’re struggling to use a large number of Goodhertz plugins on an older processor with an integrated GPU, sometimes disabling metering can help.
Enable Scroll InputBy default, all Goodhertz sliders can be scrolled in addition to dragged. If you find this behavior unnecessary, deselect this option and no scrolling events will be used to control Goodhertz sliders.
Window SizeEnlarge or shrink the Goodhertz plugin window by selecting an option here. This will save your preference for all instances of this plugin.

Automation

Unintentional digital clicks and pops are the worst. They happen for lots of reasons and often end up wasting time with needless revisions or mastering surgery. When they go unnoticed, they can make their way onto commercial albums and releases.

Plugin automation is a common cause of clicks and pops. Sweeping an EQ band, changing a delay setting, and even automating a plugin bypass can cause digital artifacts if poorly handled.

This is not true for Goodhertz plugins. Any parameter in a Goodhertz plugin, even on/off switches, can be automated freely and smoothly without clicks, pops, or zipper noises (unless otherwise noted). You can push them, pull them, LFO them — whatever you do, they’ll handle it gracefully.

Since our Master On/Off controls won’t create artifacts, we recommend that you use them rather than your DAW-supplied plugin bypass if you want to disable plugin processing.

Plugin Settings

Goodhertz plugin settings can be copied and pasted as text urls, which look like this: https://goodhertz.co/vulf-comp/3.0.9?cm=0&wf=0&lf=100&lfc=50

To copy and paste, right click anywhere on the plugin interface and select either the copy or the paste option.

E.g. If you paste “https://goodhertz.co/vulf-comp/3.0.9?cm=0&wf=0&lf=100&lfc=50” into Vulf Compressor it will recall the settings associated with that url. This way you can easily send an exact plugin setting to someone — in an email or even a tweet — without any guesswork or screenshots.
