FxSound vs Radioform

FxSound is a free Windows audio-processing application founded in 1999. It adjusts timbre, volume, spatial balance, and dynamics, with an equalizer, effects, and presets for shaping sound. The maker lists music, gaming, transcription, video, calls, and general listening as uses, and mentions Zoom calls. Audio routing and volume controls let users tailor output for their hardware. Windows downloads are offered for Intel/AMD x86/x64 and ARM64 systems. FxSound includes noise reduction, virtual surround, and equalizer controls, but no app-specific profiles. The maker says the project became free in 2022 and open-source in 2023. Its website does not use cookies or sell or rent personal information. Contact messages may contain details users provide and may support customer service. FxSound says contributors fund development, hosting, and maintenance, and invites donations. The listed plan is FxSound at free for Windows PCs.

Radioform is a free, open-source system-wide equalizer for macOS. It routes audio from Mac applications through a virtual output device and EQ engine to selected speakers or headphones. The equalizer provides ten bands from 32 Hz to 16 kHz, with adjustable gain and Q. Built-in presets cover Electronic, Acoustic, Classical, Hip-Hop, Pop, R&B, Rock, and Flat, and users can save named curves for particular headphones. A limiter and preamp are included to catch clipping when EQ is pushed hard. Radioform switches output devices without restarting and keeps equalization active after the change. It requires macOS 13.0 Ventura or later and runs on Apple Silicon and Intel Macs. The maker reports under 1% CPU usage on Apple Silicon and no audible delay. Releases are Apple-signed and notarized, with updates delivered through Sparkle. The maker says no data is collected. Radioform is licensed under GPLv3; its audio engine uses C++, while the native Swift and SwiftUI menu bar app uses macOS CoreAudio.
