EasyEffects vs Wavelet

EasyEffects is free, open-source Linux software for applying audio effects to applications managed by the PipeWire audio server. It can process application output and microphone audio sent to recording applications. Available effects include equalizer, compressor, convolver, limiter, noise reduction, reverberation, pitch shift and stereo tools, with control over their processing order. Users can process input or output streams and exclude selected applications. Processed audio can be exposed through Easy Effects Source for recording and communication applications. Configurations can be saved, imported, reused on another system and set to load automatically for selected devices. A PipeWire tab reports version, quantum values, sample rate, installed modules and loaded clients. Most current Linux distributions package the application, and a sandboxed Flatpak includes available plugins. Some distribution packages may omit plugins needed for certain effects. EasyEffects is licensed under GNU GPL version 3 or later, and PipeWire must be installed.

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.
