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 the 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 a center frequency near 650 Hz.
  • Sweet: “Airy” highs with a 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 the 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. The 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 the 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.

“In mixing, this kind of tool can be very useful for quickly altering and placing sounds in the mix. It feels less controlled than a standard parametric, but the ability to quickly get your sounds in the right ballpark cannot be underestimated.”

MusicTech, musictech.net

“As with all Sonimus products, Sweetone sounds excellent and is very simple to use. The boosts and cuts sound very natural and smooth and the filters are top-notch. The high end boosts on this unit, in particular, sounds great…”

    Excellent. Simple. Intuitif.Probant !

  2. Buddy Woodward (verified owner)

    The filters are top-notch. The high end boosts on this unit in particular sound natural and smooth. I’ve already used this in the signal chain for banjo and high-string guitar on two album projects I was hired for recently. Outstanding!

  3. Daniel R. (verified owner)

    Great plugin! It has the best high/low pass filters I’ve found yet. Sounds great on everything I’ve used it on so far, especially my snare.

    Lovely tone, maybe most hardware alike harmonics I’ve tried on a plugin … but I don’t know too much hardware, just a couple of EQ and drives

    Smooth with nice, warm push. I use it where I used to use a Furman PQ3.

  7. Ernesto R. (verified owner)

    It added a great sound in my mix.

  8. Amir G. (verified owner)

    I love this eq. I use it on EVERY mix. It gets elements of the mix in line very quickly especially if you already have good sounds to begin with. It has a sweet airy pre amp sound. Not bright but very relaxed and chill. Great plugin, Sonimus!

    Yet to use this but if it’s like any of the others it will be 5 star

    The name says it all. Instant sweetness!

  15. Kris Vasil (verified owner)

    Tilt with Character. Perfect to add body whilst smoothing out harsh frequencies (or viceversa enhance weak high end)

  16. David C. (verified owner)

    I get immediate analog vibe from this plug in which I dig. I especially like the texture with the gain knob and tailoring sounds with the Low Pass to smooth out the high end. It’s a very useful plugin to mix with and happy with this purchase.

    I love the Sonimus plugins! Sweetone was the last I needed to complete the collection.

  19. Thanos Bikos (verified owner)

    Accurately named, this EQ can’t sound bad. My standard tool when I want a source to sound balanced and natural. Broad tilts and smooth filters help bass instruments take their position in the mix, brighten a piano or give it more body, soften a harsh electric guitar speaker, smoothen a violin recorded with too much presence in the highs. The minimalistic design was intimidating at first, but it certainly helps me get where I want in less time.

    Very nice little tilt eq. Very easy and quick to use, and very nice sounding… Thanks Sonimus.

  21. Adey M. (verified owner)

    I love all of Sonimus’s plugins, Sweetone is an appropriately named eq, perfect for applying subtle, yet significant enhancement to any instrument, either at the beginning or at the end of any processing chain

  22. Stefano F. (verified owner)

    Perfect for my use with Audirvana

  23. Gino T. (verified owner)

    Sweet, does the job perfectly
