how do I make an audio recording?

[dhucks1]

Is this a standard feature or an app I need to download to be able to record, save and send audio files?

You can download a 3rd party app but I don't think you have sound recorder built in.  This is from searching other forums for the Turbo.  The icon you may see in your apps if any, is for voice commands or voice searching.  You can send audio in short clips via the messaging app where you create the sound at that point and attach.
