Microphone
You can set up and configure a microphone as an input device for Semanux Access.
You can find the microphone settings under Type of Settings: All > Input > Microphone.
You need a microphone that is connected to your computer or already built in. All laptops with a built-in webcam also have a built-in microphone. Most external webcams also have a built-in microphone – however, there are exceptions. If you are unsure whether your webcam has a built-in microphone, contact the manufacturer or seller of your device.
On Windows, you may need to enable microphone access for Semanux Access. You can find this setting under Start Menu > Settings > Privacy > App Permissions > Microphone > Allow apps to access your microphone. Alternatively, you can click on the microphone icon in the bottom right of the Windows taskbar to access these settings. Usually, this permission is already set on your device.
On macOS, you need to grant permission for microphone usage to Semanux Access.
Check the box Enable microphone as input to enable microphone input in Semanux Access. The oscillator, the white line in the black bar, will move whenever sounds are detected.
In the drop-down menu, you can select which microphone you want to use for input in Semanux Access if you have multiple microphones connected. After connecting a new microphone, press Refresh list to have it appear as an option in the drop-down menu.
You can use the microphone as a source for the detection of humming sounds.
Frequent questions
This is probably because your microphone is not properly connected to the computer. Try unplugging the cable that goes from your microphone into the computer and plugging it in again. Then click on Refresh list. It may also help if you restart Semanux Access or your computer.
If this does not help, check whether you can use your microphone in other programs. If this is not the case, the problem is with your microphone or how it is connected.
Check whether you have activated the correct microphone.
Maybe you are too far away from your microphone? Try speaking a little louder. Is there still no signal? It may help if you set your microphone to a louder input level:
- Under Microsoft Windows you can do this under Start menu > Settings > System > Sound > Input, or via the speaker icon in the notification area of the taskbar if you right-click on it and select Open sound settings. You can then increase the volume under Device properties.
- Under macOS you can do this under System settings > Sound > Input > Input volume.
If this does not help, your antivirus program may be blocking access to the microphone. You must then allow Semanux Access to access the microphone in the antivirus software and then restart Semanux Access.
The detection of humming noises is still under development and may not always work reliably. Try different types or lengths of humming noises. Please make sure that there are no disturbing noises in the background.
