Fadeo
for macOS 14 and later
The right sound for what you're doing, automatically.
Fadeo watches the app in front of you, the desktop you're on, whether you're in a meeting or heads-down. It plays, fades, or switches audio to match, on rules you define down to the second.

How it decides
Four ordered bands, every time, no surprises.
Override
Any workspace marked as an override that matches pre-empts everything else. "Meetings" pausing audio unconditionally is the canonical example.
Candidates
Every enabled, non-override workspace whose rules currently hold becomes a candidate. Usually there's one. Sometimes several apps overlap.
Tiebreak chain
When more than one candidate matches, an ordered chain narrows it to one: stickiness, specificity, priority, recency, stable order. You control the order.
Fallback
Nothing matched. Keep the current audio, resume whatever played before, or fade to silence. Your call, set once.
Workspaces
Define what a workspace is: which apps pull you into it, which Space, whether it needs a meeting or a Focus mode, even a time window. Apps can be "weak": they keep a workspace playing but never yank you into it.
Precedence
The tiebreak chain, the fallback behavior, and global fade timing, all editable, all with real numeric fields, not just sliders you have to eyeball.
Sound Library
Ambient noise is synthesized on-device in real time. No shipped audio files, no looping seams. Or conduct Spotify and Apple Music directly, including specific playlists.
Pricing
Pay what you want
$2 minimum, lifetime, one time
Fadeo is fully functional without a license, forever. The license just removes a small, occasional reminder. Pay $2 if that's what you can spare, or more if you use it daily and it feels worth it, you decide. Source is GPLv3; read it, fork it, build it yourself for free.
Get a license (email)Checkout is coming soon. For now this opens an email, reply with what you'd like to pay and I'll send a key back.
