Problems solved by technology

However, true bass enhancement is often hampered by the excursion bounds and large signal distortion of speakers used in audio processing systems
[0007] Thus, there is a problem of deciding whether psychoacoustic bass enhancement and / or real bass enhancement should be implemented in the audio stream, and if so to what extent either or both methods should be implemented

Abstract

A system and method for enhancing the real and / or perceived bass band of an audio signal is disclosed. A computationally simple yet effective bass band enhancement system for use in consumer electronics applications is disclosed. An audio processing system including bass enhancement functionality for use in a mobile audio system is disclosed.

Description

technical field [0001] The present disclosure relates to systems and methods for processing audio signals. In particular, the present disclosure relates to systems and methods for enhancing the real and perceived bass band of an audio signal. Further, the present disclosure relates to systems and methods for enhancing audio performance in mobile audio applications. Background technique [0002] Audio signal reproduction, especially in the low frequency portion of the audio spectrum (eg, bass spectrum), is generally limited by the nature and design of the loudspeaker. To provide an audio signal with sufficient bass loudness, one typically requires a large horn area, large excursion margin, and significant input power such that a sufficient amount of ambient fluid (e.g., air) is removed to achieve the desired audible loudness . [0003] Constrained by limited power availability and strict size constraints, many modern audio systems employ algorithmic devices for enhancing t...
