Audio signal processing method for e.g. loudspeaker involves implementing correction process concerning signal having smaller level than predetermined level whereby output level concerning signal of other frequency is unchanged

摘要

The method involves implementing a correction process concerning a signal of a specific frequency band in supplied audio signal. A correction process is implemented concerning a signal component, whose level is same or smaller than predetermined level in order to raise output level homogeneously. The output level concerning signal of other specific frequency is unchanged. An independent claim is also included for the audio signal processing device.
