FSK Audio has released a comprehensive 24-band dynamics processor developed in collaboration with Mark Jeffery, the original software engineer behind Pro Tools.
Following the launch of ModPlay, FSK Audio has continued its focus on tools designed to simplify complex audio processes. This latest release is the first product resulting from a 2025 partnership between the company and Jeffery.
Bark24 | Dyn is designed to offer an alternative to traditional EQs and compressors by allowing users to shape and transform sound based on how the human ear naturally perceives it.
Based on the Bark scale – a model of how humans naturally hear – the results are musical, intuitive, and fast. From polishing mixes and adding punch, to pushing sound into new creative territory, Bark24 | Dyn gives you unprecedented power to create your sonic edge.
