Compare the shrill, harsh timbres of Safari's audio playback at rates other than 1.0x with the much more respectable output from Chrome.

Apparently there is still no standard control for playback rate, so here are
some iOS style 'buttons' for you ;)
<p class="chonky">
<a href="javascript:video.playbackRate = 0.5">0.5x</a>
<a href="javascript:video.playbackRate = 0.9">0.9x</a>
<a href="javascript:video.playbackRate = 1.0">1.0x</a>
<a href="javascript:video.playbackRate = 1.1">1.1x</a>
<a href="javascript:video.playbackRate = 1.5">1.5x</a>
<a href="javascript:video.playbackRate = 2.0">2.0x</a>
<a href="javascript:video.playbackRate = 3.0">3.0x</a>
