<p>A method and system for applying reverb to an M-channel down-mixed audio input signal indicative of X individual audio channels, where X is greater than M. Typically, the method includes steps of: in response to spatial cue parameters indicative of spatial image of the downmixed input signal, generating Y discrete reverb channel signals, where each of the reverb channel signals at a time, t, is a linear combination of at least a subset of values of the individual audio channels at the time, t, and individually applying reverb to each of at least two of the reverb channel signals, thereby generating Y reverbed channel signals. Preferably, the reverb applied to at least one of the channel signals has a different reverb impulse response than does the reverb applied to at least one other one of the channel signals, t, is a linear combination of at least a sub-set of values of the individual audio channels at the time, t, and individually applying reverb to each of at least two of the reverb channel signals, thereby generating Y reverbed channel signals. Preferably, the reverb applied to at least one of the channel signals has a different reverb impulse response than does the reverb applied to at least one other one of the channel signals.</p> |
