Welcome to the group, Clea,
I play around with altering the playback speed of natural sounds a lot,
too. In fact I've recently "discovered" that many animals communicate at a
faster pace than we humans. What I mean by that is that many small animals
operate on higher "time resolution" than humans, and many larger animals
(like whales) operate at lower time resolution. To experience this, take
the fast chittering sounds of many hummingbirds and slow them to about 1/3
speed - they seem more like our own communication - we can more easily pick
up the subtleties in them. By the same token, you can speed up the "songs"
of a Humpback Whale and they sound more like either human speech or bird
song, depending on how much they are sped up.
In general animals smaller than humans (including most birds and insects)
"talk faster" than we do, and larger animals "talk slower". It helps me get
a better understanding of their communication to alter the playback speed
until it sounds more like the resolution, timing and cadence that is more
familiar to humans. I imagine that the reason for these differences has to
do with the size of the neural pathways that are used to detect, process
and actualize sounds. The smaller you are (generally) the faster nerve
impulses travel from one part of your body to and from your brain. In the
case of birds, it is well known that they have much higher frequency and
temporal discrimination than humans - interesting stuff!
