Tunity:
Tunity allows you to hear a muted TV’s audio directly to your mobile device. It acts just like a wireless headset – no need to purchase an expensive set.
Scan the TV and let Tunity locate and match the audio and stream it straight to your iPhone or iPad.
I used this app on New Year’s Day during ESPN’s broadcast of the Rose Bowl game (GO DUCKS!) and it worked great. I can see it being very useful in a sports bar with dozens of TVs set to different game broadcasts but no audio to listen to.
Sounds cool, but I would think there would be lag. Very little more annoying when watching tv than having the sound out of sync.
Maybe but there wasn’t for me. You could try it yourself to see. It’s a free app. The app also has an audio sync function. But I didn’t need to use it.
Actually, it syncs very nicely. In addition, if it doesn’t sink perfectly there is a sliding adjustment bar to get it in sync. Just tried it out tonight. It worked amazingly well even on a slow wifi connection.
Also remember, in the age of digital television live TV is nowhere close to as live as it used to be, always being several seconds behind live due to the transmission times from satellites. This gives Tunity the opportunity to sync “live” audio over the Internet in spite of internet lag.
