If others on your call can barely hear you, the most likely cause is a low input level on your microphone. Tuple on Windows relies on the system-level mic gain and cannot boost it directly. Work through these steps to diagnose and fix the issue.

​
Check your Windows input volume

  1. Open Settings > System > Sound.
  2. Under Input, select the microphone you are using.
  3. Drag the Volume slider to an appropriate level (80-100% is a good starting point).

​
Confirm the correct input device is selected

Make sure both Windows and Tuple agree on which microphone to use.
  1. In Tuple, open Settings (ctrl+,) and select the Audio tab.
  2. Verify the Input Device is set to System Default, or explicitly set it to the microphone you want to use.
  3. In Windows Settings > System > Sound, confirm the same device is set as the default input.
If Tuple is set to a specific device that differs from the Windows default, system volume controls and sliders will affect the default device rather than the one Tuple is using. See Audio preferences on Windows for details.

​
Verify microphone privacy permissions

Windows can block apps from accessing the microphone entirely.
  1. Open Settings > Privacy & security > Microphone.
  2. Make sure Microphone access is turned on.
  3. Confirm that Let desktop apps access your microphone is enabled.

​
Test your microphone before joining a call

Before joining a call, verify your mic is working at the system level. Open Settings > System > Sound and speak into your microphone. The input level indicator next to your device should respond clearly. If it barely moves, your input volume is still too low.

​
Still too quiet?

If you have followed every step above and your audio is still quiet:
  • Try a different microphone to rule out a hardware issue.
  • Check whether your microphone manufacturer provides a companion app with its own gain control.
  • Contact support@tuple.app with your Tuple version and microphone model so we can investigate further.
