Assuming the timeline frame rate is 60 frames per second, if the CHOP contains audio at its default 44100 samples per second, there will be 44100*4/60 = 2940 samples in the CHOP containing audio. This means that TouchDesigner jumped ahead 4 frames to keep up with the real-time clock. Time Slice is a Common page parameter on each CHOP and is automatically set/unset on most CHOPs.Įxample: If the current frame is 77 and the previously-displayed frame is 73, then the time slice is 4 frames long (frames 74 to 77). In contrast, the Constant CHOP is not time sliced - it it always one sample long. Many CHOPs, like the Filter CHOP cook a timeslice of samples to assure that curves are smooth and pulses are accurate, even if the TouchDesigner process is skipping frames. You can see the time slice sizes by creating a Perform CHOP and sending it to a Trail CHOP and setting Perform to the Cook and Time Slice Step channels, cook and timeslice_step. For example, if TouchDesigner skipped a frame, the time slice is 2 samples and is 2/60 seconds. If the global frame rate is 60 frames per second, the time slice is a multiple of 1/60 second. (See Absolute Time.) In CHOPs it is the set of short channels that contain the CHOP channels' samples between the last and the current cook frame.

Time Slicing keeps your overall animation smoother and more accurate, and helps keep your audio from popping when your frame rate drops.Ī Time Slice is the time from the last cook frame to the current cook frame. Time Slicing is a feature in TouchDesigner that keeps your CHOP channels smooth, even when your overall frame rate goes down and your timeline skips frames.
