Abstract:
1. A method comprising: defining a reference spectral shape based on a reference signal; deriving an estimated spectral shape for an input signal that comprises an audio signal, wherein the deriving comprises using a plurality of averagers to measure the input signal, wherein at least two averagers of the plurality of averagers comprise a short time constant averager, a mid time constant averager, or a long time constant averager, wherein the at least two averagers have different time constants; comparing, using one or more processors, the estimated spectral shape to the reference spectral shape to determine gain settings, the gain settings comprising a gain value for each filter of a filter system; automatically performing equalization on the input signal using gain values associated with the gain settings to provide an equalized signal; and outputting the equalized signal to a signal output device.
