Audio levels refer to the measurement of sound intensity in a recording or live performance. They are typically represented in decibels (dB), which quantify how loud or soft a sound is. Proper audio levels ensure that sounds are clear and balanced, preventing distortion or loss of quality. In audio production, maintaining appropriate audio levels is crucial for achieving a professional sound. Levels that are too high can cause clipping, while levels that are too low may result in background noise becoming more prominent. Tools like mixers and audio interfaces help manage these levels effectively.
