System-Level Audio EQ and Input Control for macOS

C5/10March 16, 2026
WhatA macOS utility that provides system-wide parametric EQ, per-app audio routing, and automatic input device management for Bluetooth headphones.
SignalMultiple users are frustrated that AirPods and other Bluetooth headphones hijack the microphone input without permission, and that Apple provides no system-level fine-grained EQ control — only coarse presets inside Apple Music that don't apply to other apps. People are building and maintaining open-source workarounds just to lock their audio input device, which signals a real unmet need.
Why NowThe explosion of hybrid/remote work has made premium headphones an everyday productivity tool rather than a leisure accessory, and Apple's continued refusal to add system-wide EQ or input device controls means the gap keeps widening as more people use AirPods for work calls, music, and focus.
MarketTens of millions of Mac + AirPods users; comparable products like SoundSource (Rogue Amoeba) charge $39-49 but don't solve the input-locking problem; TAM is the intersection of macOS power users and Bluetooth headphone owners, likely 20M+.
MoatDeep integration with macOS audio subsystem creates technical complexity that deters casual competitors; building a reliable, always-on audio daemon that handles edge cases across OS updates is genuinely hard and creates switching costs once users configure their setup.
