System and methods for applying bass compensation

A method of providing bass compensation for a bass response in an automobile comprising:

• low pass filtering an audio signal from an audio source with at least an 18 dB per octave low roll off;
• summing the audio signal from the audio source and the low pass filtered audio signal, wherein the summed result provides a bass boost at a first frequency and mid bass cut at a second frequency greater than the first frequency;
• and
• high pass filtering sub sonic energy from the summed result.

A bass compensation system for compensating for a response of an automobile, the system comprising:

• a 3rd order low pass filter configured to received an audio signal from an audio source and provide a filtered audio signal;
• a summing amplifier coupled to the low pass filter and configured to receive the filtered audio signal;
• and
• a 12 dB per octave sub sonic high pass filter configured to receive the summed audio signal from the summing amplifier,
• wherein the output of the summing amplifier provides a bass boost and mid bass cut to compensate for the response of an automobile.

A circuit for providing bass compensation comprising:

• an analog to digital converter configured to receive input audio signals and configured to convert the input audio signals into digital;
• a digital signal processor coupled to the analog to digital converter and configured to transform the digital audio signals to provide a transfer function that provides a bass boost in the region of 50 Hz and mid bass cut in the region of 300 Hz;
• and
• a digital to analog converter coupled to the digital signal processor and configured to convert the transformed digital audio signals into analog audio signals.
