Hidden Spectrum
Software publisher · Brand site
A publisher of Apple software and open-source Swift.
The product, from its own pages.
Hidden Spectrum, LLC is the software publisher behind Dextr and Producer Toolkit, a free macOS menu bar app for music producers and DJs with a set-time calculator, audio converter, reverb calculator and reference charts.
The company site is a static Astro build served through Cloudflare: self-hosted variable fonts, a pointer-driven parallax hero, no client framework, and a design language of deep navy surfaces, hairline borders and a spectrum-gradient glyph that carries across both products.
Hidden Spectrum also maintains open-source Swift packages, including swift-translate, a tool that translates Xcode String Catalogs and is used in production for Dextr, and SwiftLAME.
