ABSTRACT:
A dual bar audio level meter for a digital audio signal with dynamic range control decodes the digital audio signal to produce a full range audio signal and control parameters. A reduced range audio signal is derived from the full range audio signal using the control parameters, and the reduced and full range audio signals are processed to present a display having a pair of bars for each channel of the digital audio signal. The dual bars may be in the form of an inner bar representing the full range audio signal and an outer bar encompassing the inner bar representing the reduced range audio signal. A dual peak indicator also may be used to provide peak information for each channel.
