AN AUDIO COMPRESSION SYSTEM FOR COMPRESSING AN AUDIO SIGNAL

摘要

The invention relates to an audio compression system (100) for compressing an input audio signal, the audio compression system (100) comprising a digital filter (101) for filtering the input audio signal, the digital filter (101) comprising a frequency transfer function having a magnitude over frequency, the magnitude being formed by an equal loudness curve of a human ear to obtain a filtered audio signal, and a compressor (103) being configured to compress the input audio signal upon the basis of the filtered audio signal to obtain a compressed audio signal.
