Abstract:
1. A process comprising: preprocessing audio data that includes a sequence of input frames to determine parameters indicating intermediate results in a process for time scaling of respective frames of the audio data, wherein the preprocessing is performed before commencement of a real-time time scaling of the audio data, and the parameters comprise a plurality of offsets for each input frame, the plurality of offsets for each input frame corresponding to different time scales and each offset identifying for an associated input frame a block of samples for use in generating time-scaled data from the associated input frame: providing the audio data and the parameters to a device; and having the device use the parameters in the real-time time scaling of the audio data to generate time-scaled audio, wherein using the parameters in the real-time time scaling requires less processing power than would time scaling of the audio data without using the parameters.
