DeskFX Audio Enhancer changes sound played through computer speakers or headphones in real time. 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.

EqLume is a free system-wide equalizer for Apple silicon Macs running macOS 26.0 or later. It detects the genre of the current track and applies a matching EQ preset, with 21 presets that include hip-hop, EDM, rock, jazz, classical and ambient. The menu bar app shows a live spectrum analyzer and an EQ response curve. EqLume reads now-playing details from Spotify, YouTube Music, Apple Music and supported browsers, and offers transport controls for Spotify, Apple Music and YouTube Music. It uses a Core Audio process tap to capture system audio without a virtual audio driver or kernel extension. Audio is processed in memory, not recorded to disk or uploaded. Track and artist names may be sent to MusicBrainz and Apple iTunes Search for lookups. The built-in 3.5 mm headphone output uses tuned correction; other outputs can be enabled per device, while built-in speakers are unprocessed. The Mac App Store version omits the optional on-device classifier.
