there is already ABV and DANTE in the pro audio world. you are not aware of it because you probably are not in the recording/audio/music business.

bluetooth sucks because it was invented by a bunch of guys in suits and consumer electronics companies rather than people who understand latency, performance etc. i designed my own protocol in the 2.4ghz band and wrote firmware and middleware for it and it deals with all the weaknesses of BT.

BT should have been designed by those who design the products and applications and deal first hand with end users.

View on HN

BT was designed to be a general purpose peer to peer wireless communication protocol.

It was not designed to solely carry audio. It just sort of morphed into being primarily used as an audio exchange format (because it's "good enough"). A little bit like how USB morphed into a peripheral bus even though it was designed to be more all encompassing (USB Ethernet, for example). In fact, the USB protocol is somewhat mucked up by the fact that it was designed to be a network instead of a more direct connection.

Now it's actually used in this way with USB4/Thunderbolt 4.

yes, general purpose, another expression for mediocre or garbage.

i think BT wwas first designed for exchanging photos. so mass storage transfer. it should have been designed for streaming latency sensitive data like audio first, and then the “easier” scenarios could have been built on top of that.

at least with USB there was the common sense to include ISO transfers although drivers for that in OSes happened relatively late and OS vendors have ignored the standard for many years, requiring the purchase of analyzers.

in that regard there is similarity with BT but with USB it seems easier to come up with a solution as a firmware/driver/application developer. at least in my experience.

Pro stuff gives a glimpse of if we lived in a perfect world, SDI (and HD-SDI) would have been the de facto standard for video everywhere.

It's almost like including a BNC automatically rules it out of use as a consumer like there's some ridiculous royalty payment owed or something. I love BNC over every other type of connection for a coax cable. Nothing in the consumer world makes as sure of a connection.

Before entering the pro A/V industry I used to equate BNC with "ewww, old as dirt."

I then came to love the simplicity and reliability of SDI. Nowadays I work in uncompressed ST2110, and while there are many advantages of network based video and audio, paying $1,000 for a QSFP to handle just a few streams is a hard pill to swallow!

BNC == featureComplete

Bluetooth is for sure designed by committee as no sane person would intertwine software protocols with wire protocols. But here we are with an endless myriad of profile/protocol mixes all doing essentially the same thing of moving bytes back and forth through the air but with different levers for each.

USB suffers similarly but it’s not as bad IMHO

Dante is great but sadly it's proprietary. Low latency and allows you to replace a loom of analog cable with a single ethernet run.

There's Ravenna and AES67 (which I believe Dante supports), which are open standards but are not as common as Dante.

Dante supports AES67 in a degraded mode (multicast only, 1ms minimum latency, 48kHz only, at least if you're not using Dante Domain Manager).
