Why in the world do we need 3 kbps audio for voice? It's so hard to hear people speaking over mobile phones. Why don't we use 32-64 kbps 48 kHz for all voice communication? GSM CSD offers 9-14 kbps down/up, 3G offers 384 kbps, and EDGE offers 473 kbps. Why limit to 3 kbps?
- Manfred 6y agoFor situations with low bandwidth. Communication in space or far outside of civilization.
- mkl 6y agoThere are many reasons. - Not everyone has such good connectivity. - So you can handle many streams at once, like in a big meeting, without a server mixing them. - So you can have decent quality video on the same limited connection. - So you can archive large amounts of speech. - To advance the state of the art. - etc.

- drudu 6y agoif you can't answer the question yourself, you wouldn't ever be able to understand the answer. maybe i want to have two calls at once / maybe i have a shitty gsm/csd link / maybe we are transmitting over a link that has less than 10kbps bandwidth. asking this question implies you have no imagination or awareness beyond what you already know. i'll get banned from hn for this but goddamn you're a dumb person
