(dictated via notes app)

It is with great pleasure that I dictate this to you via the notes app on my cellular device please enjoy this plug-in and use it as much is your CPU allows please use it on the master bus try it on individual instruments it’s great on drum brakes and electric bass to add extreme attack please do not treat this like a classic plug-in where they tell you to not use as much bass it save presets save channel strips let this be a part of your mixing thank you.

Primary Controls

Input Gain

Varies the input gain, pre-compression.

Input Gain includes a level meter embedded in the slider. This meter shows the peak level of the input signal before Vulf Compressor’s processing.

If the signal peak exceeds or equals 0.0dB the meter color turns red, indicating that clipping could occur. Vulf Compressor 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 -24dB
  • Max 12dB
  • Default 0dB

Compression Amount

Controls the overall compression amount.

  • It’s not possible to entirely shut off the compression. Even at 0%, Vulf Compressor still imparts a bit of its signature compressor sound.
  • If you do want absolutely no compression, use the Master Mix.
  • Min 0%
  • Max 100%
  • Default 50%

Wow/Flutter Amount

Controls the depth of the vinyl wow & flutter.

Wow/Flutter Mix, Wow/Flutter Speed, Wow/Flutter Phase are all controllable in the Advanced Wow/Flutter controls.

  • Min 0%
  • Max 100%
  • Default 15%

Lo-Fi Amount

Controls overall fidelity. Higher Lo-Fi Amount produces more total harmonic distortion, decreased high frequency resolution, and more noise.

More precise control for the distortion (Lo-Fi Crunch), noise (Lo-Fi Noise Gain), & overall lo-fi flavor (Lo-Fi Type) are available in the Advanced Noise section.

  • Min 0%
  • Max 100%
  • Default 50%

Output Gain

Varies the output gain, post-compression.

Output Gain includes a level meter embedded in the slider. This meter shows the peak level of the output signal after Vulf Compressor’s processing.

If the signal peak exceeds or equals 0.0dB the meter color turns red, indicating that clipping could occur. Vulf Compressor 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 -24dB
  • Max 12dB
  • Default 0dB

Master Mix

Controls the overall impact of Vulf Compressor. At 0%, the Compression Amount, Wow/Flutter Amount, & Lo-Fi Amount processing are fully bypassed.

This mix control won’t introduce comb filtering or other unexpected blending artifacts like a standard parallel mix. Instead, it’s designed to gracefully go from bypassed to 100%.

The Input Gain & Output Gain are unaffected by the Master Mix setting.

  • Min 0%
  • Max 100%
  • Default 100%

Advanced Controls

The Advanced section offers more precise control and fine adjustment options.

To access Vulf Compressor’s advanced controls, click the ••• icon in the sidebar.


Sidechain Listen

Listen to the detector signal instead of the output of Vulf Compressor. The detector signal is what Vulf Compressor is “listening” to when calculating gain reduction.

  • Sidechain Listen makes it easy to monitor the detector signal and ensure that the sidechain is correctly routed.
  • The detector signal will be a blend of the internal and external sidechain inputs, as set by Sidechain External

Sidechain Listen includes a small meter that shows the detector signal.

  • Min Off
  • Max On

Sidechain External

Controls how much of the detector signal is from the external sidechain input. At 100%, Vulf Compressor’s gain reduction will be based on the external sidechain input only (the typical use of a sidechain). At 0%, the sidechain is fully internal (normal Vulf Compressor operation). At 50%, the detector signal is an even blend of internal and external sources.

This control might seem unconventional (because it is), but it’s very useful for dialing in exactly how much external sidechaining you want.

Here’s an example: let’s say you have a great sounding mix with Vulf Compressor on the master bus. You’d like Vulf Compressor to compress a bit more when the drums hit, but you don’t want to increase the volume of the drums in the mix. No problem! Just route the drums to Vulf Compressor’s sidechain (in your DAW) and increase Sidechain External until you’re getting enough additional compression (pumping) from the drums.

To route to Vulf Compressor’s external sidechain input, use the host/DAW’s built-in sidechain selection method.

In Ableton, sidechaining with a 3rd party plugin like Vulf Compressor is different than with a native Ableton plugin. Here’s an Ableton tutorial with more details.

If you aren’t seeing the option to sidechain with Vulf Compressor, your DAW may not realize that Vulf Compressor now supports an external sidechain. Here’s how to refresh your plugin data in a few popular DAWs:

Pro Tools


Ableton (Follow the step labeled “Rescan plug-ins”)

  • Min 0%
  • Max 100%
  • Default 0%

Advanced Compression

Comp Attack Time Constant

Modifies the speed of Vulf Compressor’s attack.

This control is unitless (i.e. not specified in seconds or milliseconds) because Vulf Compressor does not have a traditional fixed attack time (it involves a complex interaction of signal dynamics and feedback). Smaller Comp Attack Time Constant’s will clamp down quickly, damping transients. Larger Comp Attack Time Constant’s cause Vulf Compressor to react more slowly, emphasizing the attack and punch of the incoming signal.

  • Min 0.1x
  • Max 8x
  • Default 1x

Comp Release Time Constant

Modifies the speed of Vulf Compressor’s release.

Like Comp Attack Time Constant, this control is unitless (i.e. not specified in seconds or milliseconds). Smaller Comp Release Time Constant’s cause Vulf Compressor to release more quickly, often sounding louder and causing more audible pumping or even distortion. Larger Comp Release Time Constant’s cause Vulf Compressor to release more slowly and smoothly.

  • Min 0.1x
  • Max 8x
  • Default 1x

Advanced Wow & Flutter

Wow/Flutter Mix

Overall wow & flutter mix.

100% is all wow & flutter, no dry signal.

0% is all dry, no wow & flutter.

Intermediate Wow/Flutter Mix settings will produce some nice flanging effects, which can be just the right thing to spice up a vocal or melodic instrument.

  • Min 0%
  • Max 100%
  • Default 100%

Wow/Flutter Phase

Controls the stereo phase of the wow & flutter. produces a monophonic wow & flutter, whereas 180° produces opposite modulation in the left and right channels.

For some subtle stereo widening, try a Wow/Flutter Phase of 180° with a Wow/Flutter Amount around 10%.

  • Min 0°
  • Max 360°
  • Default 0°

Wow/Flutter Speed

Speed of the wow & flutter. The standard LP record is 33⅓ RPM.

Advanced LoFi

Lo-Fi Crunch

Amount of total harmonic distortion from moderate: 0%, to crunchy: 100%.

  • Min 0%
  • Max 100%
  • Default 0%

Lo-Fi Noise Gain

Controls the amount of lo-fi noise.

You can quickly turn toggle the lo-fi noise On or Off by clicking the small sidebar “noise” icon.

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

Lo-Fi Type

Selects the flavor of the lo-fi degradation.

AnalogHarmonically rich with just the right amount of dirt.
1990’s DigitalBad 1990’s digital converter with moderate aliasing.
1980’s DigitalHarsh 1980’s digital converter with some nasty aliasing.

Digital Ref Level

Digital Ref Level defines an approximate reference level as seen by the Vulf Compressor input. Lowering the Digital Ref Level is equivalent to turning up the Input Gain and turning down the Output Gain by an equal amount. This greatly affects how the signal hits the compressor and lo-fi section, and it should absolutely be used for creative effect. For louder sources, ref levels closer to 0dB may be most appropriate.

For the snappiest, attack-heavy compression, try Digital Ref Level at 0dB. For crushed & saturated compression, try Digital Ref Level at -36dB.

  • Min -36dB
  • Max 0dB
  • Default -18dB

HQ Mode

HQ Mode is our no-holds-barred processing mode where super high quality audio is given priority over CPU usage. When HQ Mode is turned ON, Vulf Compressor’s processing is internally oversampled, providing better high frequency resolution and reduced aliasing.

We recommend using HQ Mode when you need the highest possible quality and don’t mind 2-4x higher CPU usage (depending on the sample rate). An important lead instrument/vocal or master bus is a great place for HQ Mode.

HQ Mode will require more CPU resources and result in a slightly higher processing delay (latency). To ensure proper delay compensation in your host/DAW, automating HQ Mode is not recommended.

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.

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:

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 “” 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.
