1. A system comprising:
one or more processors; and
a non-transitory computer-readable medium storing instructions that, upon execution by the one or more processors, cause the one or more processors to perform operations of encoding an audio signal, the operations comprising:
rendering an audio signal presentation of audio components of the audio signal;
determining a simulation input signal configured for acoustic environment simulation of the audio components;
determining one or more transform parameters configured to enable reconstruction of the simulation input signal from the audio signal presentation;
determining signal level data indicative of a signal level of the simulation input signal;
encoding the audio signal presentation, the one or more transform parameters and the signal level data into a bitstream; and
outputting the bitstream.
