Mobile audio is awful because we are oversubscribed. My first mobile was a CDMA PCS phone. My first call on it was for a date. My date assumed I was calling from home on a land line. I was at her front door. The audio was so clean it was indistinguishable from a landline.

Later on, as CDMA phones grew in popularity, the multiplexing grew and the bandwidth shrank. Also codecs got more efficient by flattening the audio. All the atmosphere is stripped from the audio and voice calls got very sterile.

That's the beauty of FaceTime Audio. Awesome quality, as long as you aren't driving. Unfortunately, only ,y wife and I seem to use it!

I use FT Audio and whatsapp as well. FT calls are answerable right away while Whatsapp calls have a whole process: swipe, unlock, find app, open app. By the time I get in my Whatsapp caller has given up. 10 seconds later they'll make a normal cellphone call.
