Does slack feel like IRC to anybody else? Sorry I didn't mean for this to be divisive or rude. I wasn't aware this was a common observation. I'm not trying to be negative or incriminate the product. I use and enjoy slack every day.

As the infamous Jenn Schiffer said, "IRC is like Slack for old people" :)

I hope screen sharing comes soon. They bought Screen Hero a while back, and said they were integrating it.

Slack uses WebRTC, and browsers are (understandably) picky about letting websites capture the users screen. It involves having each user install an extension and/or getting on global whitelists. And Safari and mobile browsers are basically impossible.

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.

Slack's audio quality is on par with GoToMeeting, I think. Of all the different solutions I've visited (Google Hangouts, Skype, Slack, Zoom, Join.me etc.), G2M has been the most reliable and best-sounding one that I've found. It's got things like native Mac app, screen sharing (just one presenter, unfortunately), audio/video recording, telephone dial-in, calendar scheduling, and persistence (i.e. you can reuse the sa…

Not in my experience, we use G2M every day and Slack calls are much much clearer, we sometimes switch between the two and the difference is great.

I cry a little inside everytime I see that someone at work has scheduled a conference call using our terrible, terrible, expensive, 8x8 conference calling line instead of using the GotoMeeting audio. Especially when we are also already using the GotoMeeting for screensharing.

Just being able to see which person in the meeting is speaking is enough to to choose G2M, even if the call quality and reliability wasn't vastly better.

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?

If you're using RHEL, you've got a version of GLIBC that's too old, we're trying to figure out what to do about this without asking users to install a bunch of crazy stuff

Almost for as long as I can remember, there have been problems with Linux and glibc (across different distros especially). What is actually the cause of this? Recurring ABI incompatibilities?

Indeed. I'm the seemingly rare creature who was able and willing to jump through all the IRC hoops but can still understand the people who maybe can't but certainly won't.

I dunno, I get people on IRC all the time using web clients, there aren't many hoops to jump through to get on it. You don't even have to register either.

Yeah, sure if you just want to send and receive text synchronously from a public channel, each feature past that point and you have to break open your computing history book and learn some arcane incantations.

Slack audio calling is using webRTC tech. On Chrome, you can check out statistics and configuration for how they set up the call by going to chrome://webrtc-internals I checked, and it looks like they are using pretty standard webRTC settings. The audio is compressed with Opus codec. They look to be limiting the bitrate to 40 kbps. (I'm not sure, but I thought Chrome default limited the AVERAGE bitrate to 40 kbps, no…

> A lot of older VOIP tech used compression that severely limited the frequency response. I don't think that's accurate. Most conventional VoIP (in North America) uses G.711µ, whose purpose is to provide the IP correlate to logarithmically companded PCM encoding used in a normal DS0 (digital PSTN loop carrier). DS0s are not compressed. Logarithmic steps result in some approximation, but that has more to do with the m…

Thanks. You're right. I over-simplified / miss-spoke.

I believe you can use Loopback [1] for this (paid). If not, JACK [2] would certainly work but it's a bit of a hassle to get everything set up. [1] https://www.rogueamoeba.com/loopback/ [2] http://www.jackosx.com/

I also have not tried it myself, but it appears the LineIn tool on their freebies page is exactly what is needed: https://www.rogueamoeba.com/freebies/ hear the sound coming in through a microphone Edit: It is specifically called out in the Citrix blog referenced above as not working well enough. Not sure if the Loopback software would be any different, but it does offer a free trial.

The LineIn page says:

> New in 2.3: A long-standing issue with latency in LineIn has finally been cured! We've also added a menu item for toggling play-thru.

I'll try it out.

No hate towards you at all, but describing technical things as crisp drives me crazy. Can anyone enlighten me as to why that would bother my brain? Does a certain region use this or its usage widespread?

Not sure why it bothers you. Is English your first language? This kind of thing is often difficult for non-native speakers. Crisp is a word with a few meanings. In this context, it's a metaphor assigning physical qualities to sound. (A crisp dollar bill is smooth and without creases)

I grew up in Appalachia. Does that count? :P

It's probably because you have not heard it often enough to just not think about it. If I were to describe a sound as being rectangle, it just doesn't make sense and I have to think about it and try to interpret it. The extra effort in trying to decode the meaning is just annoying. In contrast, you've probably heard the phrase sharp sound. It's equally as technically meaningless as crisp sound, but you probably get i…

I think you are spot on. If they described the call as clear or sharp, I'd be fine. Crisp seems out of place even though it does convey a similar meaning.
