Abstract
A method for audio processing, the method comprising: determining at least one input audio object that includes an input audio object signal and an input audio object location, wherein the input audio object location includes a distance and a direction relative to a listener location; depending on the distance, applying a delay, a gain, and/or a spectral modification to the input audio object signal to produce a first dry signal; depending on the direction, panning the first dry signal to the locations of a plurality of speakers around the listener location to produce a second dry signal; depending on one or more predetermined room characteristics, generating an artificial reverberation signal from the input audio object signal; mixing the second dry signal and the artificial reverberation signal to produce a multichannel audio signal; and outputting each channel of the multichannel audio signal by one of the plurality of speakers.
