ABSTRACT:
The invention regards a method for processing audio signals whereby an audio signal is captured, digitized and processed in the digital domain by a digital signal processing unit or DSP, and where a processed output signal from the digital signal processing unit is converted to the analog domain and served at a transducer for providing a sensation of sound. The DSP unit is provided with mean for performing at least two different digital algorithms which delivers each their processed signal having each their non identical time delay and further the most rewarding sound signal is chosen and served at the output transducer.
