FxSound vs Wavelet

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.

Wavelet is an Android system-wide equalizer for adjusting headphone sound. It includes more than 5,000 prepared AutoEq compensation profiles and a nine-band graphic equalizer with independently adjustable controls. Other tools provide equal-loudness adjustment, bass tuning, virtualization, reverberation, attenuation, limiting, and left-right balance. Users can import their own AutoEq compensation data, with AutoEq.app and Squig.link listed as places to create it. Supported players include YouTube Music, Spotify, Plexamp, Samsung Music, and VLC for Android, although some require extra setup. The documentation lists TIDAL, SoundCloud, Amazon Music, YouTube, and other players without audio-processing support. Bass boost requires Android 9, while experimental enhanced session detection requires Android 10 or later. Wavelet has a free plan; some features use a paid in-app purchase or subscription with no expiry. Its license covers personal, non-commercial use.
