Install
Run the installer. VolumeKeys appears in the menu bar. No Terminal and no complicated setup.
Some audio interfaces and displays disable F10, F11 and F12. VolumeKeys brings them back for your chosen output. No extra window required.
45-second product tour
Watch VolumeKeys bring F10, F11 and F12 back, switch between available outputs and stay quietly in the menu bar.
How it works
Install VolumeKeys, choose your interface, and keep using your Mac the way you already do.
Run the installer. VolumeKeys appears in the menu bar. No Terminal and no complicated setup.
Choose your audio interface or display and the output you want to control. VolumeKeys remembers both.
Press F10, F11 or F12 to mute, turn down or turn up. That’s it.
More than volume keys
VolumeKeys keeps the controls simple and handles the important details in the background.
Digital monitor controller
Set and remember a separate volume for every output pair, level-match your monitors, then switch globally to compare the same track at a consistent listening level—without repatching cables.
High-precision 32-bit floating-point volume processing designed for transparent monitor control.
Digital attenuation
VolumeKeys attenuates the routed Mac signal and is not designed to add gain above the source level. Set your interface or monitor control for the physical listening level you want.
Private by design
Your audio is processed locally and is not sent to our servers by VolumeKeys. The app contains no ads or app-usage analytics.
Controlled changes
VolumeKeys fades device and output-pair changes through silence, then fades into the volume saved for the destination pair. Match different monitor pairs once and compare them at a consistent listening level without a second jump after the switch.
Hear both channels together to spot phase and balance problems.
Focus isolates everything below 150 Hz for precise low-end decisions. Night combines a 60 Hz high-pass with a 6 dB low shelf at 200 Hz—less bass through walls without thinning the whole mix as strongly.
Follows the active hardware/DAW buffer without a second competing setting.
If the selected interface or display disconnects, VolumeKeys automatically returns system playback to the current macOS default output.
Recording
Select the physical interface in your DAW for recording. VolumeKeys can control normal Mac audio at the same time.
Global shortcuts
Switch monitor pairs, toggle VolumeKeys, check mono and audition both bass modes from anywhere on your Mac.
Only available output pairs get a shortcut. Each global shortcut is registered independently, so a conflict on one shortcut does not disable the others.
Studio voices

“I press the same three keys I already use on my Mac. That is the whole point.”

“A call comes in, I tap mute, and the room is quiet. No reaching behind the screen.”

“Mono and bass checks used to mean opening another tool. Now they are in the menu bar.”

“My keyboard is now a digital monitor controller: I can switch between two speaker pairs, check Mono, and activate Bass Focus in seconds. At night, the Night setting keeps the balance while sending less low end through the walls—keeping the neighbours happy.”

Your trial starts only after VolumeKeys creates its first working audio connection. Setup time does not count.
No card required. The seven days start with your first working audio connection.

Many audio interfaces and digital display outputs do not give macOS a settable volume control, so F10–F12 stop changing the level. VolumeKeys creates a software-controlled route for compatible Core Audio outputs and brings the keys back.
VolumeKeys attenuates the routed Mac signal and is not designed to add gain above the source level. Actual loudness still depends on the source audio, interface, amplifier, headphones and speakers.
Bass Focus uses a fourth-order Linkwitz–Riley low-pass (24 dB per octave) set to 150 Hz. Two cascaded Butterworth stages create a smooth, monotonic curve with −6 dB at the labelled cutoff, while left and right are filtered independently so the low end stays stereo. Its coefficients are calculated for the active sample rate, and a 30 ms crossfade with fixed safety headroom makes switching clean without look-ahead or added buffering latency. You hear kick, bass and low-frequency buildup in isolation—not a crude one-knob EQ.
Bass Night targets long-wavelength low frequencies, which typical walls and floors attenuate less effectively and can transmit through a building’s structure. A second-order Butterworth high-pass at 60 Hz attenuates deep sub-bass; then a −6 dB low shelf at 200 Hz, based on Robert Bristow-Johnson’s biquad design, progressively reduces the remaining low end while keeping the mids and highs intact. The stereo, sample-rate-aware cascade runs without look-ahead or extra buffering and blends over 30 ms, so it sounds balanced instead of abruptly thin. It reduces low-frequency energy entering the room; listening level and the building still determine how much reaches your neighbours.
VolumeKeys needs this macOS permission to receive your Mac audio, change its level and send it to your interface. VolumeKeys does not record or upload that audio; its audio processing remains on your Mac.
The minimum system version is macOS 14.2. VolumeKeys supports Apple silicon and Intel Macs; use the free trial to confirm your exact macOS, interface and driver combination.
VolumeKeys supports compatible Core Audio outputs, including USB and Thunderbolt interfaces as well as HDMI or DisplayPort displays that appear as a standard stereo output. Drivers can still behave differently, so use the full 7-day trial as the final check.
Not for normal audio use. Internet is needed to download, buy and activate VolumeKeys. After successful activation, a paid license is designed for normal offline use, subject to its local license state and technical requirements.
VolumeKeys is a one-time purchase. The checkout shows the final price and applicable taxes before you order.
