Abstract
A loudness learning and balancing system for one or more audio channels. The system learns user volume preferences from manual interventions, providing effective and robust loudness learning to provide a consistent and balanced sonic experience. The system also reduces and/or eliminates incorrect attenuation or over-amplification of quiet interludes in the audio material, thereby eliminating artifacts such as noise pumping or breathing. In addition, the system reduces low level noise in the audio signals while preserving a wide dynamic range at most listening levels.
