I want to speed up a talking head to 110%. I've found (and read) that using the default "Maintain Audio Pitch" checkbox gives a very noticeable metallic sound to speeded up audio.
So I'm trying the "Pitch Shifter" effect. It produces a nice artifact-free shift (I set it to ratio = 0.9 for audio sped up to 110%) ...
BUT: my audio is now out of sync!
*** EDIT ***
I've figured it out. My problem, not Adobe's. You lose sync IF the video and audio tracks do not have identical start-points on the timeline. All fine if the start-points align before you change the speed.

I had weird and inconsistent artifacts as well, I fixed it (finally [weirdly]) by unchecking "use appropriate default settings" and turning the splicing frequency down all the way to 5Hz, as far as it would go.

I responded in the wrong thread, why can't I edit or delete my comments Adobe

Because of the forum software's limitations. Not even mods can 'delete' a post, has to be a staffer with special priveleges in their system.
