Adjustment apparatus and storage medium

Abstract

An adjustment apparatus for adjusting a signal level of an audio signal formed from a plurality of frames recorded in a file at discrete adjustment points corresponding to an envelope of the audio signal is provided. The apparatus includes a processor, and a memory. The processor is configured to function as an acquisition unit that acquires the envelope of the audio signal, and an adjustment unit that adjusts the envelope. The adjustment unit detects a peak value of the envelope for each frame, calculates a first average value as an average value of the detected peak values in the plurality of frames, calculates a second average value as an average value of peak values higher than the first average value, and adjusts the envelope so as to suppress at least some of peak values higher than the second average value.
