Speed up video playback causes robotic sounding audio

Pretty sure it's an html5 feature. Seen it on other discussions. Either that or other open source audio codecs.

Then I don't understand your question.

You know of a solution, use Chrome. It would appear Chrome has code within it to allow this feature.

Are you wanting that feature in iOS Safari?

Feedback for Apple goes here >>> https://www.apple.com/feedback/

Does it not work in iOS Chrome? Ask Google.

Anybody knows what causes this issue? When you adjust YouTube videos to 1.25x or even 2x speed, the audio will sound robotic and tinny.

Because you are playing the video back faster then it was recorded and meant to play.

Of course the audio is affected. If the audio played at 1x (normal) but the video at 2x (faster then normal), the audio/video sync would be off.

This isn't a YouTube issue. Even on Safari and other video players

It's a user issue.

YouTube on chrome on windows sounds way more natural when videos are sped up. It's an apple issue. I'd much rather sacrifice some CPU processing to preserve the pitch of the audio.

Safari on Mac plays worse sounds when videos are sped up because Apple doesn't preserve the pitch of the sounds. Chrome on Mac doesn't have this issue. The issue is that Apple doesn't preserve the pitch of sped up audio

So a Google proprietary feature. Use Google.

Not sure how any technology can allow a 2 minute video be played in 1 minute and keep audio sync AND not sound mechanical.

Then try the Chrome app for iPad and see if that works better for you.

Does it do it in the YouTube app?
