Sonexis

Real time macOS system audio effects

Description

Adding an equaliser or a touch of reverb to your Mac's system audio normally starts with installing a virtual sound card and routing everything through it. Then your sound settings carry a mystery device forever, it drops out after a sleep cycle now and again, and uninstalling never quite removes it. Sonexis skips that step entirely: it captures system audio and processes it live with no virtual audio device at all.

Chains are wired on a canvas. There is a Start node and an End node, and you drop effects in between and connect them, so the signal path is something you can see rather than a stack of checkboxes. Turn on automatic wiring when you just want it connected, switch to manual when you want the routing exactly so. The built-in set runs from EQ, compression, reverb and delay through stereo widening, bass boost, pitch shifting, saturation, tremolo, auto pan, chorus, phaser and flanger — and third-party Audio Unit plug-ins drop into the same chain.

Features



A visual effect chain: build it as a node graph with the signal flowing Start to End, branching and merging where you draw it. Automatic wiring hooks up whatever you drag in; manual wiring leaves the connections to you, with undo and redo throughout.

Independent left and right channels: switch the graph to Dual Mono and the two channels become separate chains that do not touch each other — reverb on one side, plain EQ on the other, no second project needed to experiment with the stereo field.

A chain per application: give Chrome one preset, Spotify another, and let everything else fall through to the default chain, switching between them from the menu bar rather than the main window. Cutting bass for video and adding space for music no longer fight each other.

Audio Unit plug-ins: AU plug-ins already installed on the system show up under the Plugins tab of the effect list and drag into a chain exactly like the built-ins.

Saved, reusable presets: store a whole chain as a preset, load it when the situation changes, or pin it to a particular app for good. Effects you reach for often can be starred as favourites.

Record the processed output: a Record control writes the post-chain audio to a file, so capturing the result does not mean adding another recorder to the loop.

Low latency with metering: an output meter sits along the top and the routing is built for stable, low-latency playback, so a parameter change is something you hear as you make it. Requires macOS 14.4 or later; GPL-2.0-or-later.
