Chffffft! That’s the sound of a wireless-mic dropout. The microphone makes a burst of noise or cuts out. That happens because the mic’s radio signal was lost, either by a weak transmitted signal, a weak received signal, or interference with other radio waves.
I'm working on a 24-bit multitrack recording in my DAW. I imported some older recordings -- 16-bit wave files -- into that 24-bit project. Does that degrade the sound quality? Also, when should I apply dither to get the best sound? - Matt, Elkhart, IN
