What Is AC Noise and How Does It Affect Audio Quality?
AC noise, or alternating current noise, refers to the unwanted hum or buzz often found in audio recordings, particularly those amplified by electrical equipment. This form of noise typically arises from electromagnetic interference, especially in environments with multiple electronic devices. Its presence can significantly degrade audio quality, making it difficult for listeners to focus on the intended sound, whether it’s music, dialogue, or effects.
Key characteristics of AC noise include:
