Abstract:
Provided are, among other things, systems, methods and techniques for loudness-based audio-signal compensation. According to one such system, an input line accepts an input audio signal; a loudness estimator, coupled to the input line, processes the input audio signal to obtain an audio playback loudness level and also provides a production loudness level for the input audio signal; and a filter generator/selector coupled to an output of the loudness estimator provides an audio compensation filter based on the production loudness level and the audio playback loudness level. The input signal is processed by the audio compensation filter to provide an output signal.

Claim (Index 24):
A system according to  claim 1 , wherein the audio compensation filter is provided by reflecting a desired loudness-compensation contour, in a frequency range between zero and a Nyquist frequency, around the Nyquist frequency and then synthesizing phase, in order to generate a frequency response.
