bossanovalithium writes “Back in 1936 — 74 years ago — boffins accepted that about 3.3Khz was the accepted frequency that telephone calls are going to run on and it’s been like that, generally, ever since. Call quality is reasonable but leaves a lot to be desired. Think calls from Skype to Skype where quality is often crystal clear.” It’s crazy to me that (for people with decent mics at least) Ventrillo sounds better than corporate conference calls.
