LineIn Audio Play-Through Utility
The positive reaction that greeted our recent post on Rogue Amoeba's free SoundSource menubar selector leads me to think that some of you might also be interested in another cool freebie from the same company. LineIn is a simple little utility, but if you need what it does, it's wonderful. It allows soft playthough for any device hooked up to an input on your Mac. That is, if you have a source hooked up to your line-in or mic jack, and you run LineIn, whatever is coming in on that jack will be played out through your standard output. Here's how I use it: my main monitor is a nice Dell widescreen with multiple inputs, which allows for picture-in-picture. I have a TV tuner hooked up to a spare input so that I can watch live TV in a small window in the corner of the main display. I hooked the audio out from the tuner to my Mac's line-in jack, and with a click of the "Pass Thru" button LineIn lets me hear the TV audio. Like I said, what it does is simple, but it does it very well.
Like SoundSource, LineIn is a free download from Rogue Amoeba's Freebies Page.
