System and method for digital signal processing

摘要

The present invention provides methods and systems for digitally processing audio signals in broadcasting and/or transmission applications. In particular, the present invention includes a pre-transmission processing module which is structured and configured to generate a partially processed signal. A transmitter is then structured to transmit or broadcast the partially processed signal to a receiver, where the signal is then fed to a post-transmission processing module. The post-transmission processing module is structured and configured to further processes the signal based upon, for example, the listening environment, profile(s), etc. and generate a final output signal.

1. A method for processing an audio signal comprising:
processing the audio signal using a pre-transmission processing module to create a partially configured signal, wherein said pre-transmission processing module comprises at least two shelving filters configured to create a 24 dB differential between high and low frequencies in the audio signal, transmitting the partially configured signal, receiving the transmitted signal, processing the transmitted signal using a post-transmission processing module to create a final signal configured for output in a predetermined environment, the post-transmission processing module being an at least partially inverse configuration relative to the pre-transmission processing module.
