Does anybody know how to resolve the intermittent static problem when recording on the Mac using Garageband 10.0.1 on a Mavericks MAC and using Apogee JAM 96k? I've tried every configuration possible (different sample rates, different bit depths, removing effects, changing guitar and interface cables etc...) to no avail. Cannot get ride of this annoying static.
Check the bit rate of garage band verses your interface. If garage band is recording at 24 bit and your interface is 16 bit, you might get static, especially if you have a lots of tracks. AC
This was happening to me too with the original Jam and Garageband 2 with Yosemite.
In Preferences->Audio/Midi, I deselected Jam as the input, then selected it again after a few moments.
Changing the bit rate from 24 to 16-bit in Preferences also helped.
Earlier, I was receiving cyclical static whenever I played a note- my first solution addressed that for me.
I think changing the bit-rate addresses the intermittent static that the OP was actually referring to. I mixed them up because they both sounded similar.
I had the same problem in Yosemite. I turned off the 24-bit option, restarted Garageband, and still had the problem. I then shut my whole computer down and restarted. Now it is gone. I think that when you set the bit rate to 16, you must restart the computer to get it to take affect.
Matching up the bit rates was the key for me. Input for the jam was 24, and the output for my headphones was at 16. Just changed the output to 24 so they match... and voila! Original Apogee Jam and 2015 MacBook running macOS Sierra.
