How to Live Stream on Twitch if you Have Pro Tools 8 and Mac OS 10.6.8

If the OCGamer can do it, so can you! Check out his channel at http://www.twitch.tv/theocgamer

There are other exhaustive and excellent tutorials on how to Stream to Twitch on Mac. However, Mike Chambers's blog post Streaming your Desktop on Mac OS X was very helpful for me, since I have a MacBook Pro OS 10.6.8. Because I have Pro Tools, I personally did not need to use Line 1 and Line 2 or Soundflower. But either way, check out Mike's blog and make sure you can get desktop footage first to stream on twitch sorted out before moving forward to adding the Pro Tools audio aspect of it.

I'm not sure what OCGamer's Pro Tools settings were, as it looks like he is running it from a PC, so I'll just show you pics and screenshots of my audio setup. Disclaimer: It's NOT perfect, as there's a low buzzing sound that I still need to get rid of. But, for my purposes of just showing people how to get some audio going, it's acceptable.

My specs:

  • Mac OS 10.6.8
  • Pro Tools M-Powered
  • M-Audio Firewire 1814
  • Shure SM-57 Microphone


1. Set your FMLE audio device settings to your PT interface. In my case, it's Firewire 1814. All the buffering and sample rate settings are based on your computer's resources, internet connection and your discretion.



2. Adjust your System Preferences > Sound




3. Program and Physically Route your PT Audio. What you'll essentially be doing is routing your PT Playback Audio (Track Name "TW Master Out 3-4")/[Balanced/Unbalanced Outputs 3-4 on the Firewire 1814] with patch cables, to [Unbalanced Inputs 1-2 on the Firewire 1814]/(Track Name "TW Wires" In 1-2, Out 1-2").



4. Input your mic, that's if you want to talk during your stream. (in my case, I used an XLR to 1/4" converter) to [Unbalanced Input 4 on the Firewire 1814]/(Track Name "TW Pre-Mic" In 4, Out 3-4. (I added another step of bussing to make my microphone louder, for my personal setup)

Here's a shot of the rear of the M-Audio Firewire 1814:

Here's the front shot of the Firewire 1814:
It shouldn't matter, but for my personal setup, I have my headphone Jack on the right side.


5. Firewire 1814 Software/Driver Settings for Mixer, Output and Hardware





Conclusion:
You probably came to this blog post because you could hear all other computer audio through your stream except your PT playback audio. Luckily, what can be heard and routed through the computer is Input monitoring. Basically, what you're doing is routing that playback audio out 3-4, into 1-2. This prevents feedback and you will still be able to speak through the Mic without echoes and hear your music audio AND have it all route to your stream! The one thing I need to work on is routing internal computer to the stream, such as Twitch Alerts notification sounds.
