Sweetone is a simple, yet powerful equalizer which combines both modern and vintage EQ characteristics to faithfully emulate analog equalizer curves. Sweetone’s preamp section is carefully modeled to lend gentle color and warmth to your digital mixes.


Key Features

  • Carefully modeled preamp transformer saturation provides genuine warmth and round high end.
    Two tone control modes: Normal (based on analog gear) and Sweet.
    Dual loud control modes: Normal and Sweet (both modes based on real vintage gear).
    High Pass and Low Pass Filters (6 or 12 dB/oct).
    Blow mode adds fat low-end warmth to HP cut frequency.
    CPU optimizations (including zero latency and no group delay) allow for a remarkably high number of Sweetone instances per session.
    Internal 64-bit floating point double precision.

A little bit of history…

Recently, we were mixing an audio production and found ourselves rushed for time. We longed for a really simple, yet powerful and effective equalizer; an EQ that could produce high quality results easily, just by turning a pair of knobs.

I talked with many colleagues and discovered our shared need for such a tool. Although together we’d tried many products, we concluded that none met our requirements one hundred percent. Equalizers that produced good sonic results were too difficult and time consuming in use. Products that emphasized ease of use, on the other hand, left us desiring higher quality results.

Shortly thereafter, I began research for development of our ideal EQ: trying and analyzing various analog devices, some of which (most of which) were lent to me. Unable to find what I was looking for in a single piece of “gear,” I attempted to combine the best attributes of several units.

Once I’d found an ideal combination of characteristics from various devices, I spent a lot of time deeply analyzing them. Having worked many weeks to get consistent testing results, I began to create a prototype from scratch. Although strict emulation of various EQ characteristics may have been enough, I decided to make some changes that in my opinion marked significant improvements.

The first release of the plugin that would soon be named Sweetone was born. I excitedly put our new tool to the test under “real world” conditions. I mixed a number of projects in order to verify our prototype met my needs for a simple to use, yet powerful and effective EQ. The results were really encouraging. I soon found I could mix entire projects using just Sweetone alone.

Next, I sent the prototype to my colleagues for use in their own professional mixes. Over the course of eight weeks, I received both encouraging comments and valuable critical feedback from qualified professionals, which helped me to further improve our prototype’s sound and functionality.

During one such discussion, a colleague noted, “your plugin has a sweet tone.” “What a great name!” I thought. Initially we called it “Sweet Tone.” But later, in the spirit of the plugin’s focus on simplicity, we shortened the name to one word: “Sweetone.”

Sweetone in depth


Sweetone has two tone modes: Loud and Tilux. Its Tilux tone mode is inspired by a single analog unit, which has been further fine-tuned with algorithmic modifications. Loud represents a synthesis of the best features of three select pieces of analog gear.

Tilux mode provides a well-balanced tone control, with a smooth high end and fat lows. Moving the knob to the left emphasizes low frequencies and attenuates treble, reducing “harshness.” Conversely, turning the knob to the right reduces low frequency information, and smoothly emphasizes highs.

Tilux has two modes: Normal and Sweet.

  • Normal: Classic tone with center frequency near 650 hz.
  • Sweet: “Airy” highs with center frequency around 2 khz.

As its name implies, Loud mode functions as a loudness filter: boosting as well as cutting selected high and low frequencies.
Loud also features two modes: Normal and Sweet.

  • Normal: Functions similarly to analog equalizers; tuned to provide smooth and pleasing enhancements.
  • Sweet: Based on two different analog equalizers (one chosen for its effective treatment of high frequencies, the other for its ideal handling of lows) and optimized with further algorithmic modifications.

Sweetone filters

High pass filter:

Sweetone provides two different high-pass filters: 6 dB/oct and 12 dB/oct. Each filter has a distinctive sound and functionality.
6 dB/oct mode provides a smooth knee, making it ideal for smooth cuts. 12 dB/oct features a more abrupt cut, making it ideal for removal of unwanted low frequencies.

Blow mode adds fat low-end warmth to HP cut frequency, and is operational in both 6 dB/oct 12 dB/oct filter settings.
Blow mode is useful in a variety of applications. For example, to emphasize sub-lows from a kick drum, activate HP Blow mode and turn the knob slowly (shift+drag) until you find the sweet spot (25hz to 50hz). Snare drum sounds can easily be “sweetened” (between 100 hz and 200 hz, for example) using Blow mode.

Low pass filter:

Low Pass operates as a high cut / low pass filter, carefully tuned to sound sweet and pleasant to the ear. Low pass has two modes: 6 dB/oct and 12 dB/oct.

Sweetone Preamp

Meticulously modeled to emulate analog transformer saturation, Sweetone’s preamp section adds warmth and sweetens highs.

  • High headroom (extending to +10 dBFS).
  • THD: -60 dBFS.

Sweetone’s preamp section‘s “Peak” LED warns when levels approach +10 dBFS. The Peak led illuminates when volume reaches levels of +9 dBFS (one decibel below digital “”hard” clipping). If clipping occurs, Sweetone’s Peak LED will remain illuminated until mouse-clicked.

Review by Joe_joe_04 at Gearslutz:

“…Going into this product review, I wasn’t sure how useful Sweetone would prove to be, mostly because I don’t tend to reach for them as much as my more complex and surgical EQs, but after some hours of experimentation, I have really begun to love this tool…”
