What is it that actually causes them to turn into wave noises? Is it just the compression mechanism once it hits some level? I've heard/thought that it was because of the frequencies that are allowed to transfer or bandwidth compression something something

yeah g711 and other voice codecs are optimized for voice so anything outside their narrow frequency band will sound like poo poo and either clip in and out or get distorted. i think if you take the original source pre-filter/adjust the frequencies with some audio editing software so it doesnt sound like poo poo and then compress it down to 8bit mono ulaw or w/e it sounds way better. altho modern PBX software may do a better job of converting things real time

of course if you have a nice new wideband codec it sounds totally fine and you dont need to do anything

Assuming the engineers who were on that project and successful have since been re deployed elsewhere. you know… vs. the telcos who’s job is to stay in top of this stuff

shower thought after reading this; would calls have actually sounded better when it was analog E2E and there weren’t digital switches and trunks did people in the 70s have to re-learn how everyone they knew sounded on the phone after being crunched through a 4KHz codec

no the usable frequency range over POTS is pretty narrow

no once it was quantized to mu-law there wasn’t really much more degradation. it isn’t like a perceptual encoding thing like mp3 where repeated sampling / reencodes make it degrade

Analog telephone would not have sounded significantly higher-fidelity than even early digital. However, it would have had a lush, forward sound, with a much wider soundstage and a less bloated presentation

i was po' so i had the 9600 pro. decent at daoc or w/e but wasn't the big kahuna e: now remembered some funy tech poo poo, my old daoc setup. two full tower machines - one a northwood p4, the other a t-bird 1.2 or w/e. ps/2 kvm. 17" crt. ugh.

getting a p4 with hyperthreading and seeing more than one cpu was pretty cool. being able to scroll a web page while playing a video on the side and having both work smoothly was pretty amazing at the time after northwood, intel basically became irrelevant until the core2 era chips in 2006 or so. barrel shifter? we don't need no stinkin' barrel shifter!

a couple years after that i was at the comp shop and had the genius idea to take home a bunch of ewaste, and thats how i ran a dual xeon linux machine with those horrible chips and four 15k sas drives in a closet that almost caught fire just due to raw heat output
