PolyFreq has just dropped its first Phonon, and it’s clearly aimed at producers who like to get deep into sound design without losing control. Available since May 5, Phonon is built around a granular engine, but instead of going full random like many tools in this space, it focuses on precision and playability.
At its core, Phonon works as a proper instrument. You get root note detection, four keyboard follow modes, and legato, which makes it feel closer to a synth than a typical granular effect. The idea here is simple: take one source and reshape it in a very controlled way using what PolyFreq calls synchronous granular or “graintable” synthesis. With sub-sample grain scheduling and separate control over grain rate and density, you can dial in everything from tight, rhythmic textures to more stretched-out atmospheres without things falling apart unpredictably.
That’s really where Phonon separates itself. Where a lot of granular plugins lean into randomness or layering multiple sources, this one gives you control over every grain. You can still get those classic cloud-like textures, but you can also push into more defined, tonal territory that actually sits well in a track.
The workflow is clearly designed to stay out of your way. Modulation is handled with drag-and-drop, most parameters are visible right away, and there’s very little menu diving. Under the hood, there’s plenty going on, with modulation sources like LFOs, envelopes, sequencers, MIDI input, sample metadata, and different noise types, all running at audio rate if needed. It’s the kind of setup that rewards experimentation but doesn’t slow you down.
The engine itself is no slouch either, offering eight voices of polyphony and up to 256 grains per voice, all running with sub-sample precision. On top of that, there’s a built-in effects chain with drive, filtering, and a utility reverb that helps glue things together or add space. Preset handling is flexible too, with sample embedding, easy export, and an eight-slot snapshot system for quickly switching or evolving sounds. The interface is resizable and works both as a standalone instrument and as a VST3 plugin inside your DAW.
In practice, Phonon covers a lot of ground. You can use it for time-stretching, pitch-shifting, and heavy sample mangling, but also for building synth sounds from scratch, generating rhythmic patterns synced to your host, or reshaping beats in more subtle ways. It’s just as comfortable designing leads as it is drifting into more abstract, evolving textures.
If you’re heading to SUPERBOOTH26 in Berlin from May 7 to 9, PolyFreq will be showing Phonon at Booth H116, with founder Nick Mariette on hand to demo it.
Phonon is available now as a standalone app and VST3 plugin for macOS 10.13 and up, and Windows 10 and up. It launches with a 33 percent discount, after which it will be priced at $89 USD, €76 EUR, or £68 GBP.
Gearjunkies take: Phonon looks like a solid first release, especially if you’ve been frustrated by how unpredictable granular tools can get. The focus on control and playability makes it much easier to actually use in real tracks instead of just sound design sessions. If you’re into reshaping samples or building new sounds from existing material, this is definitely one to keep on your radar.
