Sleep timer
Fall asleep to your mix without leaving the computer running all night at full tilt.
Click the moon icon in the toolbar to open the sleep timer. Set how long from now (or a specific time of day), pick what happens when it ends, and start it — a countdown shows next to the button while it's running.
What happens when it ends
| Action | What it does |
|---|---|
| Stop all sounds | Pauses the mix. Nothing else changes. |
| Turn off the displays, keep the sound playing | Switches your monitors off while the mix keeps going — for a dark room without stopping the ambience. Any mouse move or key press wakes them back up; audio is never touched. |
| Put the computer to sleep | A 30-second warning first, with a cancel option, since this is harder to undo mid-action. |
| Shut down the computer | Same 30-second warning. |
It survives closing the app
A running timer is remembered even if Noctívago restarts (including for an auto-update) — it comes back with the correct time still remaining. If it would have gone off while the app was closed, it only still acts if that was recent; a long-stale timer is dropped rather than, say, shutting your computer down the instant you reopen the app hours later. The "turn off displays" action specifically never fires from a stale/closed state at all — if you're back at the app, you're clearly at the machine, so blanking the screen then would just be annoying rather than useful.
Start it automatically
Tick Start this timer every time Noctívago opens in the sleep timer window, and every launch starts a timer with the last minutes (or time of day) and action you used. Before it starts, a notice tells you what it will do and counts down 20 seconds: Don’t start skips it this time, Start now starts it right away. Untick it in the same place to stop. If a timer was still running when the app closed, that one comes back instead.
Presets and a time-of-day mode
Quick preset buttons (15m, 30m, 45m, 1h, 1h30, 2h) speed up picking a duration. An "At a set time" mode counts down to the next time the clock hits a time of day you choose, instead of a plain duration from now.
