Screenbits captures audio from output and input audio devices. You can capture audio either in audio capture mode or other capture modes.
Contents
Input and output audio
Screenbits uses general terms for the audio sources which it can capture. The term output audio refers to the audio which is generated by the system and provided to an external device. This is usually the system sound which you can hear from speakers or headphones. In contrast, input audio refers to the audio generated by an external device, usually a microphone, and is provided as an input to the system.
Audio capture mode
In audio capture mode, audio devices are the only capture source so the output only contains audio, and recorder produces audio files.
- From the application window, click Audio button under Mode section.
- Under Source section, enable at least one of the input or audio devices to capture.
Other capture modes
To capture audio in a capture mode other that audio capture mode:
- From the application window, under Options section, turn Output audio or Input audio switch on.
Volume
Screenbits uses system volume settings to capture audio devices. You can use Settings app to change volume for output and input audio:
- Click Start to open Start Menu.
- Click Settings to open Settings app.
- Click System to open System settings.
- Click Sound to change sound settings.
