How To Set Volume By Time Of Day On Windows 10
Your activities vary throughout the day. Depending on your routine and the nature of your work, you might be working during the earlier hours of the day, or you might prefer the later hours of the night for work. If you work with audio files, or just like to listen to music while you work, your sound profile may vary for different times of the day. There are tools that let you set volumes for apps or for specific devices. Speaker Locker is a Windows app that lets you set volume by time on Windows 10.

Set Volume By Time
Download Speaker Locker (version 1.5, free to download and use) and run it. It is compatible with Windows 7, 8, 10, and 11. It comes with four time slots already set up. The time slots allow you to set the start and end time for when the volume level will activate and deactivate. Each time slot comes with arguments for setting the volume level.
Speaker Locker offers four distinct restriction modes for each time slot:
- Exact lock: Forces the volume to stay at precisely the percentage you set. No adjustment up or down is possible while the slot is active. For example, set it to exactly 40% and the volume is pinned there for the entire scheduled period.
- Minimum volume lock (Greater Than): Keeps the volume at or above the level you choose. For example, set it to greater than 30% and the volume cannot drop below that threshold — useful for ensuring audio stays audible during a presentation or video call.
- Maximum volume cap (Lower Than): Prevents the volume from rising above the level you set. For example, set it to less than 50% and the volume cannot exceed that ceiling — ideal for late-night listening so you don’t accidentally blast audio when a loud ad plays.
- Mute: Forces the system to mute completely for the duration of the scheduled slot, regardless of any manual adjustments. Useful for scheduled quiet hours or meetings.
You can configure up to five different time slots in total. If you need consecutive quiet periods — for example, a low-volume cap from 10 PM to midnight and a mute from midnight to 7 AM — you can set those as two adjacent slots. Overlapping slots are not recommended, as they can produce conflicting rules; it is cleaner to keep each slot’s start and end times distinct.
The application also comes with password protection which means that not just anyone can disable the app, change the time slots, or edit the volume levels. When you first run Speaker Locker, you will be prompted to create your own password as part of the initial setup — there is no pre-set default password, so choose something secure right away.
Speaker Locker is free to download and use. There is no purchase price and no trial period to worry about. The app minimizes to the system tray and is able to run on system startup, so your schedules stay active in the background without any extra steps.
Why Set Volume by Time on Windows 10
Being able to set volume by time is particularly useful in shared living or working environments. For instance, you might want louder audio during the afternoon when background noise is high, but a much quieter output late at night to avoid disturbing others. Automating this process removes the need to manually adjust your speakers or headphones every time your environment changes.
It can also be beneficial for productivity. Many people find that certain audio levels help them focus during deep work sessions, while a different volume is preferred during breaks or casual browsing. Rather than interrupting your workflow to adjust settings, a scheduled volume profile handles it automatically in the background.
Windows 10 has made some improvements with respect to the volume control it offers. The volume mixer that was a part of older versions of Windows is great in itself but there’s no way to schedule sound like Speaker Locker can. Just as you can schedule volume settings, you can also manage other system settings like Windows 11 notification control to minimize distractions during specific times.
If you need a way to automatically mute your system when you disconnect your headphones, we’ve got a little script that can do just that. Since it’s a script, it’s a free solution and works well alongside any scheduled volume tool you already have in place.
How Speaker Locker Runs in the Background
Speaker Locker is not a set-and-forget installer that works silently like a Windows service. It needs to remain running in order for your scheduled time slots to be enforced. Once you minimize the window, the app lives in the system tray — look for its icon near the clock in the taskbar. You can reopen the settings at any time by double-clicking that tray icon.
To make sure your schedules survive a reboot, enable the option to start Speaker Locker with Windows. This setting is available inside the app and ensures the program launches automatically whenever you sign in, so your volume rules are always active without you having to remember to open the app manually.
To verify everything is working correctly, follow this basic flow:
- Create or edit a time slot with your chosen mode and volume level.
- Leave Speaker Locker running in the system tray.
- Wait for the scheduled start time to arrive.
- Try adjusting the system volume manually using the taskbar slider or your keyboard’s volume keys.
- Confirm that the lock or cap is enforced in real time — the volume should snap back to the restricted level or refuse to move beyond the set boundary.
If you need to close the application entirely, Speaker Locker will prompt you for your password before allowing an exit. This prevents a child or another user from simply quitting the app to bypass the volume restrictions you have set.
What Speaker Locker Can and Can’t Control
It is worth being clear about the scope of this tool before you download it. Speaker Locker controls your system’s master output volume — that is, the overall speaker or headphone level — on a scheduled basis. It is specifically designed for that single, focused task.
What Speaker Locker does not do:
- Per-app volume rules: It cannot lock or cap individual applications through the Windows volume mixer. If you need one app louder than another, that must still be handled manually.
- Microphone or input control: Speaker Locker has no effect on your microphone level or any other audio input device.
- Audio device switching: It does not automatically switch your default playback device based on time or any other trigger.
If you need any of those more advanced capabilities, you will want a different tool — Speaker Locker is the right choice specifically when your goal is to lock, cap, or mute your speaker output volume on a schedule and nothing more.
