Well, just the above seems like enough that you'd think there'd be more (justified) grumbling that thanks to a choice made many many decades ago it's harder to distinguish young or female speakers than it is adult male ones. Maybe there is and I've just not noticed it. Is this one of the things pushing adoption of higher bandwidth audio codecs? (My guess: no.)
Not directly, I don't think, no. I suspect it's merely "why not?"
wideband codecs carry music a lot better. the can have considerably more dynamic range than you can expect from an 8 bit pcm mulaw encoding (about 45bB). that helps a lot in the speaker phone situation. if you have the opportunity to compare pstn and mp3 recordings of the same meeting like I do on occasion the difference is considerable.
