HOW TO: Record ipDTL (and system audio from iTunes, Youtube etc) on a Mac
HOW TO: Record ipDTL (and system audio from iTunes, Youtube etc) on a Mac
In this article I’ll explain how to setup your Mac in a way that allows you to record your ipDTL voice sessions into both Pro Tools & Adobe Audition.

By following this step-by-step guide you’ll also be able to record audio from the internet such as youtube as well as system sounds such as iTunes into both your favourite DAW applications.

This process should work regardless of which version of Pro Tools or Audition you are running or your Mac OS version but I’m currently running Pro Tools 12 and Audition 6 on an iMac with OS 10.8.5 installed. This guide was initially written with Pro Tools in mind but the steps are largely the same for setting up recordings into Adobe Audition. If you are only interested in using Audition follow steps 1, 2, 4 and 5.

Briefly, here’s what were going to do:

  1. Install some free software called Soundflower to serve as a software based audio device.
  2. We’ll use Soundflowerbed to route audio from Google Chrome (and the rest of your Mac system) to your audio interface.
  3. We’ll make some changes in Pro Tools so it has a dedicated pair of inputs for recording Soundflower audio.
  4. Until there is a Chrome update you’ll need to download Google Chrome 33 Beta. I’ll explain why you may need to do this, and how to so at the end of this post.
  5. We’ll change the audio hardware settings in Adobe Audition to enable you to record ipDTL.

STEP 1: To kick off you need to download Soundflower here and run the installer.

Now go to System Preferences > Sound and under ‘output’ select ‘Soundflower (2ch)’.

On my system, everything seems to work best when the ‘input’ is set to ‘Soundflower (2ch)’ just like you’ve just changed in the ‘output’ tab. By the way, doing this will temporarily kill the sound from your Mac but don’t worry – we’ll fix that in just a second. Also, Soundflower creates a 2 channel and a 16 channel software audio device but for what were doing you can ignore the 16 channel option.

Sound Output

Next, launch Soundflowerbed via your applications folder or by searching in spotlight.

Now, click the flower icon in your menu bar and in the 2ch list choose your audio interface. In my case it’s the Avid Mbox Mini.

Soundflower Menu

Try playing something from the internet or iTunes and you’ll find you’ve got sound again.

Now we need to turn our attention to Pro Tools and give it some inputs for Soundflower. To do this you need to create an aggregate audio device and setup Pro Tools to use it.

In Finder, go to Applications > Utilities and launch Audio Midi Setup.

In the bottom left corner, click the + to create a new aggregate audio device. You’ll see below that I’ve already created 3 for various other reasons – ignore the top 2. The one at the very bottom of the list called Pro Tools with Soundflower is what we’re interested in at the moment.

When you get the option to name your new aggregate device I suggest you call it something that you’ll remember later like I have done above. In the panel on the right, tick the boxes for both your audio interface and Soundflower (2ch).


Apple Audio Devices

STEP 3: If you are using Adobe Audition, skip to step 4.

You need to launch Pro Tools and in the setup menu choose ‘Playback Engine’. Click on the current engine list and choose the aggregate device you just created and named.


PT Playback Engine

What we’ve done here is give Pro Tools connections to your hardware sound card (in my case the Mbox) and Soundflower as audio inputs and outputs.

To help you make sense of the new inputs and outputs when you’re in the middle of a session you can rename them in Pro Tools. Go to Setup > I/O.

At this point your input and output lists may well look different to mine depending on how your system is configured. That’s your Microphone and the Soundflower input. Before you make any changes I suggest you click ‘export settings’ at the bottom left of the window and save them somewhere on your machine so that if what we do next stops your setup from working as you expect you can just revert back.

PT Input Settings

I changed the names of the top 2 inputs to Mic and Soundflower to make things easier for me to remember. You can change the name by double clicking where it says 1-2 etc and typing in your preferred input name. The top one with L and R under 1 and 2 is more than likely to be your microphone input from your audio interface. The second row where the L and R correspond to 3 and 4 is more than likely your Soundflower channels but this may depend on your system.

Once you’ve got this all running correctly I strongly suggest you click the ‘export settings’ button at the bottom of the window and save these somewhere on your computer. That way if something goes wrong in future you can just reload the settings.

Next, open a new Pro Tools session and create a stereo track for Soundflower and a mono one for your mic. On the stereo track, change the input to whatever you named your soundflower input. Make sure the input on the mono track is your mic as below. (Doing this will allow you to record yourself and your colleague via ipDTL onto separate tracks in Pro Tools.)

PT Tracks & Inputs

To test that it’s all working so far, mute your Soundflower channel and start it recording, then get some music playing in iTunes. (You may need to mute the Soundlower channel in Pro Tools to avoid hearing your music twice with a tiny delay). Now you should see your iTunes music recording into pro tools.

Hopefully everything is working and whatever you play in itunes and indeed from other applications like Spotify or Youtube, you’ll seen them rolling into Pro Tools. Before we try it with ipDTL I suggest you do the following.

Save the current setup in Pro Tools as a template – perhaps call it ipDTL or System Sound Recorder. That’ll make life easier when you need to do this next time.

HANDY HINT for all Soundflower users…

You can add Soundflowerbed to your Mac’s list of login items so that you won’t have to think about it again. Go to System Preferences > Users & Groups > Admin and then on the tab at the top choose ‘Login Items’. Click the + at the bottom left and add Soundflowerbed to the list.


Up to this point the information has been relevant to anyone who wants to record audio from their system, the internet or iTunes etc into Pro Tools using a Mac computer. However for some reason to do with the way Google Chrome currently works, you will more than likely need to complete one important final step to be able to record your ipDTL sessions into Pro Tools. (This will probably become unnecessary when the next general release version of Chrome is made available).

Although you can hear audio from ipDTL during a conversation, if you are using the current version of Chrome which is version 32 it will not record sound into Pro Tools. So to record your ipDTL sessions into Pro Tools you’ll need to download and install Google Chrome 33 Beta here. The bug that prevents recording in Chrome 32 has been resolved in this Beta 33 version so once you’ve installed it (You’ll have to over write your existing version of Chrome) you should be ready to record from ipDTL into Pro Tools.


As is shown in the screen grab below you need to configure your Audition audio hardware settings as follows:

Launch the software and go to Audition > Preferences > Audio Hardware. In the Input box select ‘Soundflower (2ch)’. In the Output box below, select your Audio Interface (i.e your Mbox etc)

As long as your 2ch Soundflower setting is set to your Audio Interface and your Macs own System Preferences > Sound settings are set to output audio to ‘Soundflower (2ch)’ you should be good to go.

I hope this guide has been useful. Please feel free to comment below although I’m afraid that because everyone’s system will vary I can’t offer individual technical support.
