Method and system for enhancing bass effect in audio signals

A system for enhancing bass effect in audio signals, the audio signals having a first input channel and a second input channel, the system comprising:

• a first and second low pass filter coupled to receive the first and second input channels, respectively, and operable to extract low frequency components of the first and second input channels;
• an exponential block coupled to receive the low frequency components of the first and second input channels and operable to produce an output signal;
• a band pass filter operable to limit the frequency range of the output signal to a predetermined frequency range and produce a band filtered output signal;
• and
• a first mixer operable to add the band filtered output signal to the first input channel;
• and
• a second mixer operable to add the band filtered output signal to the second input channel.

A method for enhancing bass effect in audio signals, the audio signals having a mono input channel, the method comprising the steps of:

• a. extracting low pass frequencies of the mono input channel producing low frequency components of the mono input channel;
• b. passing the low frequency components of the mono input channel through a exponential transfer function to produce an output signal;
• c. filtering the output signal by a band pass filter to produce a band filtered output signal;
• and
• d. adding the band filtered output signal to the mono input channel producing a resultant output signal.
