Live Playback With ipDTL, Soundflower and TwistedWave

This morning I was lucky enough to do an ipDTL test with the fantastic Atlanta-based talent, Lance Blair. For those who aren’t familiar with it, ipDTL is an internet solution that allows one studio to connect with another (or any user with Google Chrome) in the comfort of your pajamas. Well, that is until they introduce a video feature…

The purpose of the test with Lance this morning was to try out the latest features added to ipDTL. Rather than list them all here, I’ll advise you to check out Lance’s blog as he summarises them very nicely and also included a sample of how ipDTL recordings are sounding these days (hint: it’s good).

While testing the new build, I managed to get live playback working with Soundflower, TwistedWave and ipDTL. Soundflower is a handy little tool that allows applications to pass audio through to other applications. I feel like Soundflower was always on my Mac, but if you don’t have it, it’s possible to download it. TwistedWave is the audio editor of choice for many Mac-using voiceover professionals.

I’ll attempt to share with you how I achieved this simple setup, but bare with me – I’ve never done one of these screen-capture whose-a-ma-whatzits before. If I had it my way I’d invite you all into my studio to crowd around the computer and have a gander.

So, once you have started your voiceover session with your client who loves to hear the audio played back…you record a few takes. Your client says “Hmmm…could I possibly hear the second take played back???”


Ok, so first of all, you want to make sure that you have your secondary source on ipDTL is set to Soundflower (2ch) as shown below.


Then you’re going to go to TwistedWave and to Preferences > Devices > Output device and change that to Soundflower (2ch).


Then all you have to do is hit OK, go back to the audio and play whichever part you want to. You won’t hear it (unless you’re able to tinker with some other settings), but your listener will. I’m sure that there is a workaround to hear what they hear on the other end, and if anyone has any suggestions I’d love to hear them.

There you have it! Playback on an internet-based ISDN replacement.
