Lossy artifacts, on demand

When our friend Tyler Duncan (an incredible producer & mixer) wanted a certain drum fill to reek of the 90’s — to sound like a low bit-rate digital MP3 ripped from KaZaA — he turned to Goodhertz for answers.

This got us thinking. Bitcrushers exist, but Tyler didn’t have 8-bit in mind, he wanted lossy digital audio: streaming music on a 56k modem. What if a plugin could degrade digital audio & capture that quintessential compressed sound in realtime?

Lossy gives you the nasty (beautiful?) artifacts of heavily deconstructed audio in a highly-tweakable realtime plugin.

Whatever you now find weird, ugly, uncomfortable and nasty about a new medium will surely become its signature. CD distortion, the jitteriness of digital video, the crap sound of 8-bit - all of these will be cherished and emulated as soon as they can be avoided.

Primary Controls


Lossy’s reverb was inspired by the 1980’s reverb algorithms developed by Keith Barr and other pioneers of the first digital reverbs. Though it’s not a realistic-sounding reverb and doesn‘t sound like Carnegie Hall or Concertgebouw, it does sound extremely reminiscent of the reverbs used by electronic musicians in the early 1990’s (Aphex Twin, Squarepusher, Boards of Canada, etc).

Despite being pretty much the most “digital” reverb we could make, it has a warmer, almost organic quality.

Verb Position

Sets whether the Verb is applied Pre- or Post- Lossy and Filter processing.

Option About

Reverb applied before Loss section


Reverb applied after Loss section

Applying reverb before Loss adds more sound to be Lossified, for a more full and expansive effect

Applying reverb after Loss sounds more like a traditional reverb, adding space to the original Lossy sound

  • Default Pre

Verb Amount

Controls the amount of reverb applied.

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


Filter Mode

Switches between Normal, a bandpass filter, and Inverted, a bandreject filter.

Option About

Frequencies inside the filter range are audible and those outside are cut


Frequencies outside the filter range are audible and those inside are cut

  • Default Norm.

Low Cut Freq

Controls the center frequency of the low cut.

  • Min 20Hz
  • Max 10.0kHz
  • Default 20Hz

High Cut Freq

Controls the center frequency of the high cut.

  • Min 40Hz
  • Max 20.0kHz
  • Default 20.0kHz

Filter Slope

Varies the filter slope for both high cut & low cut.

  • Min 6.0dB/Oct
  • Max 96.0dB/Oct
  • Default 24.0dB/Oct


Loss Mode

Option About

Lossy data compression reminiscent of a low bit-rate digital MP3


Everything stripped away in Standard mode

Phase Jitter

Simulates inaccuracies in phase and timing due to imperfect clocking

Packet Repeat

The skips and spaces of a bad connection

Packet Loss

Fills the spaces of Packet Loss with repeats of the previous audio

Standard + Packet Loss

A combination of Standard and Packet Loss modes

Standard + Packet Repeat

A combination of Standard and Packet Repeat modes

  • Default Standard

Loss Amount

Varies the amount of lossy data compression.

Lossy is a creative tool and is not based any any particular lossy codec or standard (i.e. it’s not a MP3 codec checker).

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

Loss Speed

Controls how quickly the data compression algorithm acts.

Slower speeds have more spectral smear, faster speeds tend to sound more garbled.

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

Loss Gain

Overall gain of the Lossy signal.

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

If the signal peak exceeds or equals 0.0dB the meter color turns red, indicating that clipping could occur. Lossy 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 -24.0dB
  • Max 24.0dB
  • Default 0.0dB

Master Mix

Controls the overall Lossy mix.

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

Master On/Off

Bypasses Lossy’s processing.

Options: Off, On

We recommend using the Master On/Off instead of your DAW’s plugin bypass to avoid digital artifacts.

  • Default On

Advanced Controls

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

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

Verb Decay

Controls the length of the reverb decay. 0% is very fast, and 200% is very slow.

  • Min 0%
  • Max 200%
  • Default 100%

Auto Gain

Enables automatic gain compensation.

Auto Gain helps keep the perceived volume the same, even when much of the audio information has been removed due to data compression.

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

Gate Threshold

Threshold below which the audio is silenced.

  • Min -96.0dB
  • Max 0.0dB
  • Default -96.0dB

Stereo Mode

Option About

Left and right channels are processed independently.

Joint Stereo

Left and right channels are processed together. Generally produces a stereo image that is truer to the source.


Left and right channels are summed to mono.

  • Default Stereo


Option About

Frequencies weighted using a psychoacoustic model


All frequencies weighted equally

  • Default Perceptual

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.

Right-Click Preferences

Action Explanation
Language Switch the display language of text elements in Goodhertz plugins. We currently support the following languages: English, Spanish, Portuguese, French, Japanese, Korean, Chinese (Simplified), Chinese (Traditional), and Arabic.
Always Open Advanced Pane By default, this is Off — 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.
Dark Mode Allows you to choose the color palette used for displaying the interface. If you prefer the look of dark colors (or work in a darker environment) enable this option. The Auto option will automatically adjust the color scheme depending on the system preferences of your machine (Mac only).
Enable Metering By default, this is On — 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 Input By 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.
Enable Tooltips By default, this is On — i.e. all controls will show a tooltip on hover. If you find this behavior unnecessary, deselect this option and no tooltips will be shown.
Require Double-Click for Keyboard Focus By default, you can get keyboard focus on any Goodhertz control with a single click. Enable this option to ensure keyboard focus only occurs on double clicks.

Unintentional digital clicks and pops are the worst. They happen for lots of reasons and often end up wasting your 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.com/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.com/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.”
