audio on screen recording with powerpoint

Question

playback of screen recording in powerpoint has poor audio

Answer 1

Dear @Iain Duffy,
Thank you for posting your question in the Microsoft Q&A forum. I understand that the audio in your PowerPoint screen recordings is poor or unclear during playback.

To better assistance, could you please confirm following information:

• What exactly sounds wrong: too soft, muffled, distorted, or robotic?
• Were you trying to record system audio (e.g., voices from videos or calls) or only your microphone? (PowerPoint records mic audio only by default.)
• Does this happen with all your recordings or only certain ones?
• Has PowerPoint or Windows been updated recently?

In the meantime, I recommend some steps below:

• Please check your microphone and system sound levels.
• Try closing unnecessary background applications that may affect audio processing.
• If you need system audio captured, consider using a different recording tool, since PowerPoint does not capture system audio by default.

Please understand that our initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution.

I truly appreciate your patience and understanding. If you have any further questions or need further clarification, please feel free to reach out. I'm looking forward to hearing from you. 

Thank you for your cooperation.

Answer 2

If you're experiencing poor audio quality during playback of screen recordings in PowerPoint, it may be due to several factors. Here are some potential causes and solutions:

1. Network Connectivity: If the screen recording was made while using a poor network connection, it could affect audio quality.
2. Audio Processing: The audio processing module in the browser or application may be causing degradation in sound quality. If the audio sounds robotic or distorted, this could be a sign of packet loss.
3. Volume Levels: If other audio is playing loudly while you're recording or during playback, it may interfere with the clarity of the recorded audio. Reducing the volume of other sounds can help.
4. Recording Settings: Ensure that the audio settings in PowerPoint are configured correctly and that the Desktop Experience feature is installed if you're using a server version of Windows.

To troubleshoot, you might want to check the audio recordings captured during the screen recording process to identify where the issue lies. Comparing the audio before and after processing can help pinpoint the problem.
