Has anyone else noticed how pristine the audio quality of a Slack call sounds? I wonder how they optimized it. My company's voip, and Lync, and Skype all fail to deliver the same kind of call quality. I've only noticed / admired better call quality when making a call within Cisco to another employee. I don't use video much but I hope they've done as good of a job as they did with audio.

I'm not sure what codec those products use, but I wouldn't be surprised if Slack went for Opus. Seems like it's the most popular choice these days, with little competition. (Discord also uses Opus.)

Slack uses Opus.

Earlier quoted context omitted.

Wow quick to the low effort Slack is just IRC comment. In my opinion Slack does something that is often very undervalues and easily overlooked, it is like the opposite of a death my a thousand cuts - superiority by a thousand minor improvements. When taken individually or even in handfuls none of the features are that impressive, but cumulatively it creates a much better product. This was very apparent to me at least…

> So yes Slack is to IRC, as the Ford Model T is to a Mercedes S-Class. I think you mean the other way around.

You're correct. Fixed.

I'm pretty sure they use Pied Piper compression.

*Wow, tough crowd.

Slack calls have been broken in linux for a while--even though they worked when calling first launched. Is a fix for that on the horizon?

What? No they're not. I use them every day on Fedora.

Interesting. I wonder if a dep changed. They don't work in Ubuntu 14.04.

lovely.

the sooner i can remove skype from my life the better.

that said, why can't any of these phone systems deal with the use case of two people trying to call each other and then simply auto connect the two calls? why does one side have to drop the call and answer the other?

Probably a wide band or at least mid-band codec. One thing I learned working with VOIP is people perceive quality based on what they have been using recently, which for most people is the absolutely horribly stepped on audio of skype, cheap voip, or the cellphone network. Carriers have pretty much let their baseline audio quality go to \\\\ because no one cares anymore. (Remember the Sprint pin-drop campaign?) Now, when you give somebody a wide band high quality audio connection they are blown away.

bad enough that I can be reached after work via slack and get calls while I'm on a commute (which is never compensated for aside from general salary), it'll have video?

also, this only works in Chrome and on mobile, which is really messed up considering that Firefox is also a bleeding edge browser.

No to mention the pristine UX of the "call failed" screens. Ugh. I love Slack, don't get me wrong, but the calls fail to connect about 50% of the time for me when I'm connected to my work VPN. Work VPN seems fast for everything else, just Slack calls crap out while using it... I don't have the same problems with Skype or Google Hangouts -- opened tickets with Slack and was told, "Don't use a VPN with our service..." Uh... cool, right, will get on changing my work policy around this. =P
