In this paper, a real-time implementation of a punch metering plugin is described. ‘Punch’ is a perceptual attribute and can be defined by both temporal and frequency characteristics of an audio signal. The metering tool consists of signal separation, onset detection, and perceptual weighting stages. Scores are displayed on both a time graph and a histogram; statistical metrics are derived from the histogram. The output is compared to subjective punch scores obtained from a controlled listening test. Additionally, critical evaluation of the tool is performed by experienced mixing and mastering engineers. The meter is intended to allow for optimisation and objective control of punch during mixing, mastering, and broadcast.
