AB  - In a recent work, we reviewed the basics of level detection for dynamic range compression, and presented various tunings of level detector parameters for optimal correspondence with well-known and recently-proposed facts pertaining loudness perception. In the paper, we review key points, and present several extensions. We review the mathematics behind the operation of the popular root-mean-square detector, with special attention paid to the effect of time constant on detector performance. We compare an equal loudness filter, designed in the prior work to compensate for frequency-dependent steady-state loudness perception, to standard weightings. Updated results based on newly standardized loudness contours are also presented.
