Superior tone-shaping, from mix to master

Tiltshift is the most intuitive and effective way to shape your sound.

The guiding principle of EQ plugins often seems to be: more is more. More bands, more peaks, more valleys, more parameters to learn, and more metering to focus on. While we do appreciate a full-fledged multiband EQ when it’s needed, we’ve found that oftentimes, they’re not the right tool for the job. “More is more” also means more complication, more signal mangling, more phase distortion, CPU-usage, etc., and less productive mixing or mastering, less musicality and creativity.

Tiltshift is a new type of tilt EQ that does more with a lot fewer controls. More than any other EQ, Tiltshift is able to dramatically alter the tone and timbre of your audio while sticking to the first rule of mastering: do no harm. By using extremely gentle slopes (often less than 1 dB per octave), the relative phase, frequency, and transient response of the audio is preserved, making it easier to find the right global EQ curve before focusing on specifics, and Tiltshift‘s perceptual loudness lock technology makes it easier to compare EQ settings without being influenced by simple gain changes.

So what if there was less in an EQ? Meet Tiltshift: superior tone-shaping, suitable for anything from mixing to mastering.

Primary Controls


Tilt Gain

Varies the amount of spectral tilt.

This simple slider is the heart and soul of Tiltshift. In theory, you might never need to touch another slider, because simply tilting forward or backward provides extremely musical, natural-sounding tonal variation.

Negative values tilt the sonic spectrum toward the bass.

Positive values tilt toward the treble.

Want something warm & full sounding? Try tilting towards the bass -3 dB.

Looking for something bright ala Studio 54? Try tilting towards the treble, +3 dB.

What does Tilt Gain’s decibel value represent? It specifies the exact amount that the treble & bass are boosted or cut in opposing directions. For example, for a Tilt Gain of +6dB, the treble is boosted +6dB, while the bass is cut -6dB.

  • Min -18.0dB
  • Max 18.0dB
  • Default 0.0dB

Tilt Range Low

Tiltshift was primarily designed for wide, gradually-sloping tilts across the entire frequency spectrum. However, there are times when you may want to tilt a smaller portion of spectrum. For this reason, we included Tilt Range Low & Tilt Range High, which control the range in which the tilt EQ operates.

For example, let’s say you’re making a bass track brighter by tilting up the treble, but you don’t want to boost anything above 2 kHz. By setting Tilt Range High to 2 kHz, you can limit the tilt range to level off above that frequency. Get this setting.

Looking to tilt just the “air” in your track? Drag the Tilt Range Low to something up high, like 10 kHz, and push the Tilt Range High up as high as it can go, 24 kHz. Then tilt up the Tilt Gain just a little — voila, more presence in your sound’s high atmospheres. Get this setting.

  • Min 10Hz
  • Max 12.0kHz
  • Default 20Hz

Tilt Range High

High frequency point for the tilt range. See Tilt Range Low.

  • Min 20Hz
  • Max 24.0kHz
  • Default 20.0kHz

Tilt Loudness Mode

Unlike a typical tilt EQ, which always boosts & cuts an equal amount in either direction, Tiltshift is smarter. With Tilt Loudness Mode set to Auto, the loudness is automatically matched for any tilt setting using our perceptual loudness locking technology. This makes comparing EQ settings much easier and makes it possible to perform more natural sounding tilt automations.

Tiltshift’s Filter section perfectly complements the Tilt section: the Tilt shapes the overall frequency spectrum while the Filter further refines the extremes of the frequency range. Use it for anything from filtering out DC offset on a master, to more creative applications, like recreating the response of a guitar cab or cellphone.

Filter Listen Low

The “Listen” function allows you to audition the audio that the low cut filter is removing.

Options: Off, On

Filter Listen Low is very useful for helping to dial in the appropriate Filter Range Low & Filter Slope Low for what you’re trying to accomplish.

For example, if you’re trying to remove some low frequency pops and plosives from a vocal, use the “Listen” function to help set Filter Range Low so that you are hearing mostly plosives and not important components of the vocal itself.

  • Default Off

Filter Listen High

The “Listen” function allows you to audition the audio that the high cut filter is removing.

Options: Off, On

Filter Listen High is very useful for helping to dial in the appropriate Filter Range High & Filter Slope High for what you’re trying to accomplish.

  • Default Off

Filter Range Low

Controls the corner frequency of the low cut filter.

The frequency response at this frequency is -3 dB if Filter Resonance Low is set to 0 dB.

When Filter Range Low is at its minimum value, the low cut filter is bypassed completely.

  • Min 4Hz
  • Max 12.0kHz
  • Default 4Hz

Filter Range High

Controls the corner frequency of the high cut filter.

The frequency response at this frequency is -3 dB if Filter Resonance High is set to 0 dB.

When Filter Range High is at its maximum value, the high cut filter is bypassed completely.

  • Min 8Hz
  • Max 24.0kHz
  • Default 24.0kHz


Output Gain

Varies the output gain.

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

If the signal peak exceeds or equals 0.0dB the meter color turns red, indicating that clipping could occur. Tiltshift 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 -96.0dB
  • Max 12.0dB
  • Default 0.0dB

Master On/Off

Bypasses Tiltshift’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 Tiltshift’s advanced controls, click the ••• icon in the sidebar.

Advanced Filter

Filter Slope Low

Continuously varies the steepness of the low cut filter in dB per octave.

  • Min 6.0dB/Oct
  • Max 48.0dB/Oct
  • Default 12.0dB/Oct

Filter Resonance Low

Controls the amount of filter resonance at the Filter Range Low frequency.

Filter Resonance Low allows you to boost at the very same frequency where the low cut begins to act. This may seem counter intuitive: why boost something that you’re intending to filter out? Because it can sound awesome.

Here’s an example: imagine you have a beefy kick drum that has too much sub bass energy around 40 Hz. To reduce the sub bass, you set Filter Range Low to 60 Hz, thereby rolling off everything below 60 Hz. You’ve effectively tamed the excessive sub energy, but you find that now the kick drum sounds a bit weak and thin. By setting the Filter Resonance Low to 6 dB, you can bring back some of the kick drum’s power and bass, while still cutting excessive sub bass. Win-win.

  • Min 0.0dB
  • Max 18.0dB
  • Default 0.0dB

Filter Slope High

Continuously varies the steepness of the high cut filter in dB per octave.

  • Min 6.0dB/Oct
  • Max 48.0dB/Oct
  • Default 12.0dB/Oct

Filter Resonance High

Controls the amount of filter resonance at the Filter Range High frequency.

  • Min 0.0dB
  • Max 18.0dB
  • Default 0.0dB

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, Tiltshift uses a higher precision algorithm, providing better spectral resolution at the expense of higher CPU usage.

Options: Off, On

We recommend using HQ Mode when you need the highest possible quality and don’t mind 2-4x higher CPU usage. An important lead instrument, vocal, or a mastering session is a great place for HQ Mode.

  • Default Off

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 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.”
