1. A method comprising:
receiving, by an audio processor, a multi-channel input audio signal;
determining a first set of dynamic range control (DRC) values configured for controlling a dynamic range of an output audio signal;
determining a second set of DRC values configured for preventing the multi-channel input audio signal from clipping during downmixing by the audio processor;
applying the second set of DRC values to the multi-channel input audio signal to obtain an attenuated multi-channel input audio signal;
downmixing the attenuated multi-channel input audio signal to obtain a downmix signal, wherein the downmixing is frequency-invariant; and
generating the output audio signal from the first set of DRC values and the downmix audio signal.
