| 摘要 |
The invention relates to a method and system for reproduction of sound signals con- tained in a low frequency effect (LFE) channel in an audio reproduction system com¬ prising at least one main loudspeaker - although typically either five main loudspeakers in a surround sound system or two main loudspeakers in a traditional stereophonic system - and at least one low frequency loudspeaker (subwoofer) for reproduction of the lowest portion of the audible frequency range. According to the method and system of the present invention, the frequency range of the LFE channel is subdivided into a first frequency region below a given cut-off frequency, which first frequency region is provided to the subwoofer, and a second frequency region above said cut-off frequency, which second frequency region is provided to at least one of the main loudspeakers. |
