A DSP (digital signal processor) processor having a gain reduction function processes an audio input signal to produce a current audio meter value, and a current gain reduction value. A logic processor then generates a timecode event record in response to receiving a new time value, and saves the timecode event record in a table. Each timecode event record contains the new time value, the current audio meter value, and the current gain reduction value. Concurrently, the logic processor retrieves timecode event records from the table for a predetermined range of time values. The logic processor plots the meter values and gain reduction values against the time values of the retrieved records to produce a waveform representation of the audio signal and the corresponding gain reduction. A display then displays the waveform representation of the audio signal and the corresponding gain reduction.
