I am using (first-time) Audacity version 2.0.2 on my desk-top which has Windows XP (also using a SnowBall , Blue, USB microphone to record voice). Need help with settings because can’t get anything to record and can’t hear anything on play-back. Thanks.
Set up your Snowball mic according to the instructions: http://www.bluemic.com/snowball/#/support/
Then open Audacity and you should see a USB option in the recording section of the Device Toolbar http://manual.audacityteam.org/o/man/device_toolbar.html
Select the USB option as the recording device.
Select your normal sound card as the playback device.
Press the record button.
Also if you do want to hear the mic while recording, turn on Transport > Software Playthrough, but this inevitably has a delay (latency) so you will probably not actually want to do this.
