Abstract:
Disclosed is a method of processing a signal such as an audio signal. The method includes normalizing a received signal to a level of between −2 dB and −10 dB to yield a normalized signal, compressing the normalized signal exceeding a threshold (such as 70% of the maximum volume and above) to yield a compressed signal, performing frequency equalization on the compressed signal to yield an equalized signal; and normalizing the equalized signal.
