Mac, OBS and Streaming Audio Right

OBS has for some time been working on it’s new version of OBS which is called OBS studio, and is cross platform. Finally we are free from having to faff about with WireCast, we can now just plug and play and Stream away. BUT WAIT it’s not just that simple!

If you ever tried Minecraft’s in game streaming it will at least (force) prompt you to download additional required software to get you going.

This software (whilst not needed, (well it’s not but you are a idiot if you don’t setup your audio properly)) will get your Audio going properly on OBS streaming when you are not using additional Hardware.

This piece of software is called Soundflower, and is an example of Virtual Audio Cabling, which basically creates a software based Sound Card inside your computer in order to route audio more usefully!

Installing

So first things first, grab yourself a copy of OBS Studio, you can find the latest version on GitHub here. Download and install!

Next we’ll grab a copy of SoundFlower which is on their site here or GitHub here.

SoundFlower will need you to restart your Computer.

Getting Setup

Lets fire up OBS Studio:

OBS 0.9.1

I’ve got a few extra scenes setup, but this is the layout you’ll be presented with!

We are going to add a source, (first make a scene of course) in this case a “Audio Output Capture”

Audio Selection

And then, to keep things simple, just select the SoundFlower 2 Channel. We don’t need to do anything wacky.

Input Select

Finally we need to change the Sound Settings under System Preferences. So open System Preferences and Sound. And select Soundflower (2ch) as the Output device.

System Prefs Sound

Now suddenly everything will go quiet as all your audio is being sent to OBS/Soundflower: (it’s good to check that OBS is actually detecting at this point)

Audio Monitoring

We need to route the Audio from your computer via Soundflower back to Speakers/headphones. For this open SoundflowerBed:

SoundFlowerBed

It’s under Applications/Soundflower, this fires up a Menu Item in the Top Dock

Top Menu

Just click that, and send the Soundflower (2ch) back to “Built in Output/headphones” And now both you and OBS can hear everything.

Soundflower Routing

Your computer’s audio is now sent to this device and captured by OBS.

(You can tell as my mic here is picking up my speakers):

And there we go 🙂

BONUS

(Billy May’s Voice) BUT WAIT THERES MORE!

Xbox 360 Controller on Mac under Yosemite?

Unofficial Release 0.14 works fine and it’s on GitHub here

BONUS BONUS

Now what do you do if you get Beachball of Death when trying to use the SoundflowerBed Icon from the menu?

First open Terminal (sorry).
Then type:

ps aux | grep Soundflowerbed.app

Then you’ll see something like this:

SoundflowerBed Hunt

Then type:

kill 9331

Where 9331 is replaced with the number here:

SoundflowerBed Kill

It is VERY important you kill the right thing. As otherwise you might break something and have to restart the whole computer.

Once you have kill’ed SoundflowerBed, just reopen and all should be good.
