Overshoot in the crossover region of multiband dynamic range compression (DRC) systems is an issue that is encountered in several audio applications such as hearing aids, audio mastering tools, and portable loudspeaker systems. This overshoot translates into a loss of overall loudness due to reduced post scale headroom, digital clipping, or allowable output above a chosen threshold. This paper introduces a gain compensation filter in the limiter gain computation path in each band, thus preserving the audio quality and loudness of the system. Furthermore, a couple of methods for calculating the optimal compensation filter is presented along with analysis of the two and three band DRC systems with and without the proposed solution.
