I have audio that is being sent to my MBP through an audio in line that I would like to monitor for audio quality. The only way I know how to listen in real time to the audio is by way of Audio Recorder, but it seems a little unnecessary to have a recording application open simply to listen to my media that is being sent in. Is there a feature already part of OS X that allows me to turn this on? I looked in system prefs, but couldn't find anything to enable this. I will resort to audio recorder if I have to, but would be very happy if this was already a feature.

Haven't seen that ability for a long time. (built-in)

I use "Line-In". It can route from any input to any output, with "Pass Thru" option. I use it sometimes to monitor Amateur Radio transceiver audio, either through another USB device (iMic) or the Mac's line-in.

It might be possible to set that up with Apple MIDI Setup, but it's a bit more cumbersome.

"Line-In" is very simple - you can hide it after launch, if it clutters your desktop too much.

Thanks

This thread saved me big time, by downloading the free LineIn program I am able to use an audio cable from my TV to my Macbook and listen via headphones to my tv without keeping my room mate awake. ( I know it would be much easier to just get a 3.5mm extension cable for my headphones but I'm in college, and I've gotta deal with what I've already got. THANKS AGAIN!
