Does changing the video quality on YouTube affect audio quality?
You can manage video quality settings on You. Tube without affecting audio quality. It means, when you change ( increase/decrease ) video quality on You. Tube, it will not affect audio quality. The streaming audio part is easier to stream compared to video. In most cases audio quality works also fine with slow internet connection.
Another frequent inquiry is “Does Youtube change audio bitrate after a video is uploaded?”.
Audio playback bitrate is not related to video resolution. So it seems audio quality is the same, irrespective of the selected video resolution. However, the audio quality will be as good (or bad) as the original video that was uploaded to You, and tube. Never mind my answer. @Psychogeek is right and You. Tube does indeed change audio bitrates and codec.
Does compressing audio affect video quality?
Since the audio and video is not two separated tracks, which is aligned and played simultaneously with each other, but rather one file format with both video and audio included. This means that the more compression you put on this one file, lowering the video quality that is, the more you’ll experience a decline in overall quality.
The lower the quality, the more You. Tube compresses the video, which means small bits of data are being removed to get the video to you more efficiently. The consequence of this however is the audio quality suffers, especially on the high end, where sounds begin to sound tinny at lower quality.
