eqMac

eqMac provides a system‑wide audio processing suite for macOS, allowing users to apply parametric equalization and volume control to any audio output. The application offers three equalizer modes—from a basic bass‑mid‑treble preset to an expert mode with unlimited bands, adjustable gain, bandwidth, frequency, and multiple filter types—plus a graphical spectrum analyzer. It also includes a per‑application volume mixer, headphone presets for thousands of models, and spatial‑audio simulation of different listening environments.

The software supports all macOS audio devices, including built‑in speakers, Bluetooth, AirPlay, USB, HDMI, and Thunderbolt, and can handle separate left/right channel equalization. Users can customize the interface, create super presets that switch automatically based on output device or active application, and host external audio units for additional effects. Additional features include hotkey control, cloud‑synced presets, recording to MP3, file rendering with applied effects, a virtual output for routing audio to other apps, and an HTTP API for remote or programmatic control.

Designed for macOS 10.13 and later on both Intel and Apple Silicon, eqMac targets users who need fine‑grained audio tuning across the entire system, from casual listeners to audio professionals seeking a flexible, integrated equalizer and mixer.
