Abstract
Various embodiments describe audio signal processing. In an example, a computer system generates metrics, such as RMS levels, for audio slices from a foreground audio signal. A summed-area table is generated from the metrics. An observation window is used to determine whether to add a key frame or not. The observation window includes a set of audio slices. A total metrics, such as an average RMS level, is computed for the audio slices in the observation window. Based on the total metric, the computer system adds a key frame. The key frame references audio ducking parameters applicable to a background audio signal.
