Abstract

Audio playback through miniature loudspeakers is bounded by the loudspeaker's limited dynamic range. How to compress the audio and simultaneously preserve the original artistic effect is worthy of study. Traditional peak-based and RMS-based dynamic range compression (DRC) methods do not consider the audio loudness characteristic that may influence the perceptual artistic effect. This paper proposes a novel compression and compensation method based on Zwicker's loudness model and equal-loudness contours. The proposed method aims to provide a high-quality audio playback by mapping the audio's loudness to a smaller range, while preserving the perceived spectral balance of the original audio. Subjective listening tests are performed to demonstrate the benefits of the proposed method.
