Patent ID: 8676361

Claim:
A method for enhancing audio signals, comprising: receiving an audio signal; separating the audio signal into component signals corresponding to discrete bands, wherein the component signals comprise a full bandwidth component signal, a bass component signal, a midrange component signal, and a treble component signal; processing the component signals with distinct processing pathways to obtain processed component signals, wherein the distinct processing pathways include a full bandwidth pathway for processing the full bandwidth component signal without sound-level decompression, wherein sound-level decompression comprises widening a dynamic range of one or more of the component signals after compression, a bass pathway for processing the bass component signal with sound-level decompression, a midrange pathway for processing the midrange component signal with sound-level decompression, and a treble pathway for processing the treble component signal with sound-level decompression; determining a sound delay of each of the component signals based on at least a gain ratio parameter and a target level parameter used in processing each of the component signals, the gain ratio parameter representing a dynamic ratio of the envelope of signal input versus signal output up to a target level, the target level parameter representing a maximum number of bits allowed for compressor output; aggregating the processed component signals to recreate a standard signal in one or more channels, the aggregating compensating for the sound delay of each of the component signals; and performing additional post-processing on the standard signal.
