Abstract
A method and a system for improving the low-frequency sound reproduction of an audio signal, the sound reproduction being performed by an audio system comprising at least one loudspeaker. The system includes a low-frequency sound enhancement module with filters for separating an input audio signal into a high-frequency signal and a low-frequency signal. The system is configured to implement a first audio processing of the low-frequency signal to obtain a low-frequency output signal and a second audio processing of the high-frequency signal to obtain a high-frequency output signal. The low-frequency sound enhancement module includes, for the first processing of the low-frequency signal, a module for increasing the dynamic range of the low-frequency signal, which is parameterised as a function of at least one transient part of the low-frequency signal.
