Some embodiments of the invention provide a computer system for processing an audio track. This system includes at least on DSP for processing the audio track. It also includes an application for editing the audio track. To process audio data in a first interval of the audio track, the application first asks and obtains from the DSP an impulse response parameter related to the DSP's processing of audio data. From the received impulse response parameter, the application identifies a second audio track interval that is before the first interval. To process audio data in the first interval, the application then directs the DSP to process audio data within the first and second intervals.

Method and apparatus for efficiently accounting for the temporal nature of audio processing

A method for displaying a gain control interface having a gain level display with non-linear gain levels. The gain level display has a first end having an associated first pixel offset value and a second end having an associated second pixel offset value. A range of pixel offset values span from the first pixel offset value through the second pixel offset value. The method includes receiving a plurality of pixel offset values in the range of pixel offset values, calculating a gain level value for each of the plurality of pixel offset values (whereby a difference between two pixel offset values of two gain level values having a gain level difference is not equal to a difference of two pixel offset values of any other two gain level values having the same gain level difference), and mapping a gain level value to a pixel offset value.

A method for reducing data events representing a parameter of a signal as adjusted by a user through a control interface during a time period. The method includes receiving a series of data events where each data event has a parameter value of the signal and a time-based value associated with the parameter value that corresponds to an instance in time during the time period. The method further includes processing three data events in the series of data events and eliminating one of the three data events based in part on the parameter values of the three data events relative to each other.
