A technician is troubleshooting a laptop’s built-in microphone that is creating a lot of noise in recorded audio. The latest drivers are installed, and the microphone is set as the default recording device. Which of the following actions will BEST alleviate the issue while maintaining audio clarity?
Adjust advanced equalizer settings to filter frequencies that are contributing to noise.
Update the laptop’s operating system to the latest version.
Disable all other input devices through the audio settings.
Enable noise cancellation or suppression features in the sound settings.
Enabling noise cancellation or suppression features in the sound settings can help reduce background noise during audio capture without affecting the clarity of the primary audio source, which in most cases would be the user's voice. Updating the operating system or disabling other devices would not directly address the issue of noise in the audio capture. Playing with advanced equalizer settings may help to some extent but is not the most effective method to deal with noise issues compared to using built-in noise reduction features.
