# Quiet microphone on Windows

> Troubleshoot low microphone volume when using Tuple on Windows.

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](/application-preferences/windows-preferences-audio) 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](mailto:support@tuple.app) with your Tuple version and microphone model so we can investigate further.
