It runs on Windows and macOS and works with music services, streaming TV and movies, games and other computer audio. Effects include equalization, amplification, reverb, chorus, wahwah, vibrato and tremolo. Users can layer an unlimited number of effects and choose from more than 30 presets. Equalizer options are visual, graphic and parametric, with a system-wide equalizer of up to 20 bands. NCH also describes uses in gyms, foyers, retail locations and waiting rooms, including pink-noise masking for privacy; low latency and CPU use are listed as suitable for live-stream applications. The free version is for non-commercial use. A commercial quarterly license is $9.99 a month, billed quarterly and renewing automatically. Annual licenses are $34.99 a year for personal use and $39.95 a year for commercial use; both note +VAT/year. System requirements list Windows 7 through 11 and macOS 10.9 or above.

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.
