Subaudio, DC Offset, and How they Affect Your Digital Sound

Subaudio are sounds below the range of human hearing–below about 20 Hz. While we can’t hear these sounds, they can make their way into our audio files in various ways and cause some issues for us. Understanding these issues can help us make decisions in tracking, mixing, and mastering to ensure clean bass sounds and the highest possible fidelity in our recordings.
