In this very brief tutorial, I walk through how you can use ASIO4ALL to multitrack record multiple USB microphones.
In order to do this you’ll need the following:
1) A Windows Computer
2) Multiple USB Microphones, ideally a different model for each participant
3) ASIO4ALL (http://www.asio4all.org/)
4) ASIO Capable Recording Software (such as Adobe Audition, Reaper, Cakewalk Sonar, etc)
