Original Abstract Submitted

encoding/decoding an audio signal having one or more audio components, wherein each audio component is associated with a spatial location. a first audio signal presentation (z) of the audio components, a first set of transform parameters (w(f)), and signal level data (�) are encoded and transmitted to the decoder. the decoder uses the first set of transform parameters (w(f)) to form a reconstructed simulation input signal intended for an acoustic environment simulation, and applies a signal level modification (�) to the reconstructed simulation input signal. the signal level modification is based on the signal level data (�) and data (p) related to the acoustic environment simulation. the attenuated reconstructed simulation input signal is then processed in an acoustic environment simulator. with this process, the decoder does not need to determine the signal level of the simulation input signal, thereby reducing processing load.
