The Realtek HD Audio Manager is a driver that handles sound playback and recording on many Windows computers. The program has several features, such as equalizers and environmental effects that you can configure for optimal playback. Recording with Realtek HD Audio Manager requires configuring the settings to indicate how you want to record.
Plug a microphone into your computer's audio input or microphone jack.
Right-click on the Realtek HD Audio Manager icon in the system tray. Select "Sound Manager."
Click "Microphone." Adjust the "Recording Volume" slider as you wish.
Click "Noise Suppression" to cancel out background noise. Click "Acoustic Echo Cancellation" to prevent whatever you're recording from playing back through your speakers and being picked up by a microphone. These two settings are optional.
Select the "Default Format" tab. Select a sample rate and bit rate from the drop-down menu.
Click "OK" to close the audio manager.
Right-click on the Realtek HD Audio Manager icon again. Select "Sound Recorder."
Press the "Start Recording" button to start recording. Press "Stop Recording" to stop or pause. A pop-up window will ask where you want to save the recording. Navigate to an appropriate folder on your hard drive, then press "Save" if you're finished recording. Otherwise, click "Cancel." Press "Resume Recording" when you want to start recording again.
