1. A method, comprising: receiving audio data corresponding to a plurality of audio channels; receiving, with the audio data, transient information, wherein the transient information comprises at least one of a transient control value indicating a definite transient event and a transient control value indicating a definite non-transient event; determining audio characteristics of the audio data, the audio characteristics comprising additional transient information; determining an amount of decorrelation for the audio data based, at least in part, on the audio characteristics; and processing the audio data according to a determined amount of decorrelation, wherein the process of determining additional transient information involves analyzing a portion of the received audio data to detect a soft transient event, wherein the soft transient event corresponds to a non-binary intermediate transient control value indicating neither a definite transient event nor a definite non-transient event, and wherein the process of processing the audio data involves: applying a decorrelation filter to a portion of the audio data, to produce filtered audio data; and mixing the filtered audio data with a portion of the received audio data according to a mixing ratio, wherein the process of determining the amount of decorrelation comprises reducing an amount of decorrelation in response to detecting the soft transient event, reducing the amount of decorrelation involves modifying the mixing ratio, and modifying the mixing ratio is based, at least in part, on the transient information.
