Hi there. Not as far as i know. Either in the windows control volume or in the preferences menu of Audacity, you can only choose 1 sound card at a time. From: David Engebretson Jr. Sent: Friday, March 20, 2015 4:41 PM To: audacity4blind@xxxxxxxxxxxxx Subject: [audacity4blind] multi track recording I'm curious; is it possible to have two USB devices recording into Audacity at once? I have two stereo mixers (Peavey USB8 and Berringer Q1202) and would like to record the data from them simultaneously. Any help appreciated. Best, David
