Abstract

An audio enhancement technique comprises an audio source. Presets for the input audio sound are provided. The presetted ausio sound is tone adjusted to create a tone adjusted presetted audio. The tone adjusted presetted audio is expanded to create an expanded audio and the expanded audio is outputted for use by user. The presetted audio is subjected to a treatment by one or more modules to improve sound quality. The treatment comprises processing the audio source by the following modules: a low pass filter with dynamic offset; an envelope controlled bandpass filter; a high pass filter; and adding an amount of dynamic synthesized sub bass to the audio. The processed audio signals are combined in a summing mixer with the audio source to create an audio out signal. In one embodiment, the expanding comprises sending audio out to a block that splits, processes and combines the stereo stream into several different versions that are fed into the Stereo Bus A; feeding Stereo Bus A output to a Compare Block that adjusts the amplitude of the original and processed audio by averaging; and feeding the output from the compare block as an stereo output. In one embodiment, the tone adjustment comprises: a first section for adjusting a low frequency tone; a second section for adjusting a mid frequency tone; a third section for adjusting a high frequency tone and mixing the audio outputs processed by the first, second and third sections to produce an output audio sound.
