Radio shows converted to podcast, 2x with the silence cut out. Radio folks talk sooooo slow.
Most podcast, 1.75ish
Audio books, 1.5-2.
This is with head phones, if I'm listen on speakers I tend to need it slower.
I started at 1x but slowly ramped it up.
For a while when I'd watch dvds alone, I'd speed those up too. Can't really do that with streaming so not so much anymore.
I understand the research supports listening faster, most folks can listen faster than they can talk.
