Abstract
The present invention provides for methods and systems for digitally processing an audio signal to reproduce high quality sounds on various materials. In various embodiments, a method comprises filtering the signal with a low shelf filter and/or high shelf filter, passing the signal through a first compressor that, filtering the signal again with a low shelf filter and/or high shelf filter, processing the signal with a graphic equalizer based on a selected material profile, passing the signal through a second compressor, and outputting the signal to a transducer.
Claims22
A method for processing a signal comprising:
- filtering the signal with a first low shelf filter;
- filtering the signal received from the first low shelf filter with a first high shelf filter;
- compressing the filtered signal with a first compressor;
- filtering the compressed signal with a second low shelf filter;
- filtering the signal received from the second low shelf filter with a second high shelf filter;
- processing the filtered signal with a graphic equalizer based at least in part on a material profile;
- compressing the processed signal with a second compressor;
- outputting the signal to a transducer.
The method as recited in 1 wherein the first low shelf filter and high shelf filter are configured to create an approximate 24 dB differential between high and low frequencies in the signal.
A method for processing a signal comprising:
- filtering the signal with a first low shelf filter, using a pre-transmission processing module;
- filtering the signal received from the first low shelf filter with a first high shelf filter, using the pre-transmission processing module;
- compressing the filtered signal with a first compressor, using the pre-transmission processing module;
- transmitting the signal;
- receiving the transmitted signal;
- filtering the signal with a second low shelf filter, using a post-transmission processing module;
- filtering the signal with a second high shelf filter, using the post-transmission processing module;
- processing the filtered signal with a graphic equalizer based at least in part on a material profile, using the post-transmission processing module;
- compressing the processed signal with a second compressor, using the post-transmission processing module;
- outputting the signal to a transducer.
An audio system comprising:
- a first low shelf filter configured to filter a signal;
- a first high shelf filter configured to filter the signal received from said first low shelf filter;
- a first compressor configured to compress the filtered signal;
- a second low shelf filter configured to filter the compressed signal;
- a second high shelf filter configured to filter the signal received from said second low shelf filter;
- a graphic equalizer configured to process the filtered signal based at least in part on a material profile;
- a second compressor configured to compress the processed signal, and
- a transducer configured to output the signal.
