AB  - Audio recorders benefit from pre- and postemphasis, which reshapes the noise spectrum to match human audibility thresholds. A 10-dB increase in apparent dynamic range is realized for some digital audio systems. A first-order boost based on the CCITT J.17 preemphasis standard is shown to be appropriate for dynamic range expansion. A survey of peak acoustic levels present in 36 music performances is also included.
