Need help delaying system audio? This does the job

I was trying to find a way to get MLB Gameday Audio to sync with postseason TV broadcasts, and this app does it brilliantly. I’d like to explain how to do this for users who may not have it completely figured out.

First, you’ll need a copy of Sound Siphon to enable using your Mac’s system sound as an input for apps like BatCrack. Just get the demo version from the developer’s website; you only need the paid version if you want to pass through audio from specific apps. Passing through all of your Mac’s audio is totally free, even though you’ll get a registration prompt when you launch the app. Once you’ve started up Sound Siphon and switched it to “On,” hold down the alt/option key and click the volume icon in your menubar. Your output device should be set to “Sound Siphon.” Next, launch BatCrack, and set your desired delay either by clicking on the box and dragging or by clicking and then typing in your desired delay. Also pay attention to the volume slider in the BatCrack window – it’s muted by default, so if you want it to play your delayed audio at the same level you have your system volume set to, drag the slider all the way to the right. (When you do this, it should say 0.0 dB.) Make sure you have your “Audio In” set to “Sound Siphon” and your “Audio Out” set to built-in, or whatever output device you have plugged in to your Mac, if that’s relevant to you.

Now you’re ready to go! Fire up Gameday Audio and your delay should be properly set up. If you’re having trouble with the volume, or if you’re hearing the non-delayed audio overlapping the delayed audio, alt-click the volume icon again to go to Sound Preferences and make sure the “Mute” box is ticked under for Sound Siphon in the “Output” tab. You can also adjust the volume slider for your internal speakers in this window (or for whatever output device you’re using) so it’s set to the preferred level. Just make sure you select “Sound Siphon” as your output again before you exit the System Preferences window.

I highly recommend BatCrack for anyone who wants to sync TV and radio broadcasts for sporting events. The interface could be a little more user-friendly, but this is a great app that does just what it’s supposed to do!
