FSK Audio and Pro Tools Pioneer Mark Jeffery Unveil Bark24 | Dyn, A 24-Band Dynamics Processor That Thinks Like Your Ears
SAN FRANCISCO, CA, UNITED STATES, December 2, 2025 /EINPresswire.com/ -- FSK Audio, the Northern California software company behind ModPlay, today announced the release of Bark24 | Dyn, a powerful 24-band dynamics processor developed in collaboration with legendary audio developer Mark Jeffery, the original software engineer behind Pro Tools.
Following the success of ModPlay—the groundbreaking “plug-in for plug-ins” concept that turns modulation into a playable creative experience—FSK Audio continues its mission to empower modern creators with tools that simplify complex processes and inspire experimentation. In 2025, Jeffery entered a partnership with FSK Audio to create a new generation of audio plug-ins built for today’s music enthusiasts and audio professionals. Bark24 | Dyn is the first release from this collaboration and is a tool that invites users to shape, discover, and transform sound in ways that go far beyond traditional EQs and compressors.
Mark Jeffery“Our goal with Bark24 | Dyn was to give artists a way to work with sound the way they actually hear it,” said Jeffery. “Instead of thinking in Hertz and numbers, you shape dynamics in musical regions—clarity, presence, warmth—the same way your ears and brain perceive them.”
Shape, Discover, and Transform Your Sound
For producers and musicians chasing a creative edge, Bark24 | Dyn opens up sonic territory never before accessible with a standard compressor or EQ. Using 24 frequency bands based on the Bark scale, a psychoacoustic model of how humans perceive sound, it analyzes audio through the lens of the ear itself. The result: processing that feels musical, intuitive, and fast.
With Bark24 | Dyn, creators can:
•Achieve transparent limiting with frequency-aware precision.
•Enhance or soften transients only where needed.
•Reveal hidden textures and details within a mix.
•Move effortlessly from subtle correction to chaotic sound design.
Why It’s Different:
•Frequency-Focused Control: Dynamically adjust volume across 24 critical bands aligned with human hearing, delivering surgical yet musical results.
•Musical Results: Dial into the “edgy,” “warm,” or “boomy” regions the ear recognizes instantly without hunting for Hertz values.
Built for Speed: Draw and slide threshold curves, A/B modes instantly, control groups of bands at once, or let auto-threshold adapt dynamically to your audio.
•From Subtle to Extreme: Polish a mix, add punch to a performance, or tear a sound apart for creative chaos. Bark24 | Dyn behaves like a true instrument for sonic exploration.
About the Bark Scale
The Bark scale is based on psychoacoustics, which is how the brain perceives sound. Each of Bark24 | Dyn’s bands correspond to a “critical band” of hearing, reducing masking between adjacent frequencies and focusing control on the spectral regions that matter most to human perception. This approach yields cleaner, more transparent, and more musical results.
Bark24 | Dyn is available now for $99 USD (limited-time launch sale, regular MSRP $129.95).
