20 - UTILITIES - DSP FUNCTIONS
PROCESSING TIMES
Being off-line processes, all the DSP functions take time to process the data. With
timestretch and pitch shift, the actual time it takes depends on the preset being used but
generally, all the DSP functions take about 3 x the length of the audio being processed. In
other words, a 10 second cue will take around 30 seconds to process. You will note, of
course, that if you are processing stereo cues, this time doubles. Likewise, if you try to
process multiple tracks, the time it takes will increase proportionally.
