This short tutorial will walk you through the steps to allow you to use two USB microphones on one Mac to create a recording.
* Macintosh with 2 USB ports
* Two USB microphones (they can be XLR mics with USB interfaces)
* WireTap Studio ($69) http://www.ambrosiasw.com/utilities/wiretap/
* Two humans who want to talk on the air
Advantages of this method include: You don’t need a complicated mixer and you do get the two voices on two separate channels so they can be independently adjusted and edited.
Disadvantage of this method is that WireTap Studio requires you to edit the recording when you’re completely finished, you can’t stop and edit and then move on without creating multiple files.
Install WireTap Studio
WireTap Studio will be used to record both microphones on separate channels. First install the application and then we’ll configure it in the next step.
Configure WireTap Studio
On the floating window, use the pulldowns to select your two USB microphones. In this example we’re using a Heil PR20 XLR mic that is plugged into a Blue Icicle USB interface, so that’s the first mic chosen, the second mic is a Samson C01U mic.
Edit Recording in WireTap Studio
Note that the two mics are on two separate channels – the Blue Icicle is the tan color while the Samson is blue. They have independent gain control on either side and you can also apply effects to the two channels independently before exporting the file out as an AIFF or other format file. Note also that all edits in WireTap Studio are non-destructive.
