I have been looking for a player that does a good job playing lectures. I mention lectures rather than podcasts as lectures are sometimes old recordings or recordings that are lower quality. Often audio enhancements are needed to make these pleasant to listen to. Also need is variable speed playback with automatic pitch correction
for those instances when a speaker speaks too slowly or too rapidly.
Human speach is centered within a narrow part of the audible range, so it should be easy enough to make audio enhancements which will maximize the clarity of noisy spoken word files.
It seems like most players being made now are made for teenagers who want to watch You Tube videos on a tiny screen. There are those who want to use a player for more serious purposes.
