Issue descriptionUserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.86 Safari/537.36 Example URL: https://www.youtube.com/watch?v=YQHsXMglC9A Steps to reproduce the problem: 1. Play https://www.youtube.com/watch?v=YQHsXMglC9A with 1.05 speed (for example, set playback rate by dev tool) What is the expected behavior? Less distortion What went wrong? There is noticeable distortion between 3:10 and 3:30 (the drum sound) Did this work before? N/A Is it a problem with Flash or HTML5? HTML5 Does this work in other browsers? N/A Chrome version: 50.0.2661.86 Channel: n/a OS Version: Flash Version: Shockwave Flash 21.0 r0 Would Chrome consider a better pitch correction algorithm to reduce audio distortion?

Can you expand a little more? Listening to the example in 1.5x and 2.0x provided as options in YouTube, I thought the speed up algorithms did a good job. Are you noticing something specific with 1.05x with the algorithm? +jks to get an expert golden ears opinion too.

Hmm, it seems play with 1.05x and 1.04x is more noticable. I tried 1.1x, 1.25x and 1.5x. Is this as expected?

I tried to play with 1.05x and 1.04x, by setting video.playbackRate in devtoolbar. I don't hear obvious distortions. When playbackRate is high, >2, the audio and video are both fast, but I assume that's expected. xinyuzhang@, can you explain what's your expectation?
