1. An audio signal processing system, the system comprising:
- an audio signal processing module for processing an input audio signal with a sound spectrum and outputting an audio output signal processed with the sound spectrum; and
a sound spectrum selection module capable of selecting the sound spectrum from a plurality of different sound spectra responsive to additional information that is associated with the input audio signal, where the additional information is available to the audio signal processing module together with or parallel to the input audio signal.

Abstract
An audio signal processing system where an input audio signal is processed with a suitable sound spectrum to form an audio output signal for outputting via a loudspeaker or other means. The audio signal processing system may include a sound spectrum selection module capable of automatically selecting a sound spectrum from a plurality of different sound spectra suitable for processing the input audio signal and changing that sound spectrum whenever there is a change in the source of the input audio signal.

15. A method for processing an audio input signal with a sound spectrum, the method comprising:
-
receiving the input audio signal from an audio signal source;
receiving additional information from the audio signal source that is associated with the input audio signal;
selecting the sound spectrum from a plurality of sound spectra responsive to the additional information;
processing the input audio signal with the selected sound spectrum; and
producing an output audio signal from the processed input audio signal. - View Dependent Claims (16, 17, 18, 19, 20, 21)
