SYSTEM AND METHOD FOR DIGITAL SIGNAL PROCESSING IN DEEP DIVING ENVIRONMENT

摘要

The present invention relates to a system for processing of an audio signal relating to a diver in a deep diving environment. The system comprises an input device structured to receive the signal, a pitch changing module configured to change the pitch of the received signal, a plurality of processing modules collectively configured to process the pitch changed signal and produce a processed signal. The present invention is further directed to a method for processing of an audio signal relating to a diver in a deep diving environment.

1. A system for processing of an audio signal relating to a diver in a deep diving environment, said system comprising:
an input device structured to receive the audio signal, a pitch changing module configured to change the pitch of the received signal, a first low shelf filter module configured to filter the pitch changed signal, a first high shelf filter module configured to filter the signal received from the first low shelf filter module, thereby creating a first filtered signal, an automatic gain control module configured to adjust a gain of the first filtered signal, a second low shelf filter module configured to filter the gain adjusted signal, and a second high shelf filter module configured to filter the signal received from said second low shelf filter module, thereby creating a second filtered signal.
