I've long held the opinion that many audio compression codecs have outlived their usefulness, and now simply introduce latency and reduce audio fidelity to preserve bandwidth that is no longer in short supply.

Every internet connection I've had over the past 10 years in the US has been fast enough to send and receive at least a dozen uncompressed CD-quality PCM streams simultaneously. On paper, my current fiber connection should be able to handle 1,400 of them. This insistence on audibly mangling the audio to keep it at ~96 kbps makes less and less sense every day -- especially considering how the audio is usually carrying all the important information in the call anyway!

(I find the same thing happens on streaming services too. 98% of the bits are for video, 2% for sound.)
