TAutoSlidingWindow | Unreal Engine 5.6 Documentation

API > API/Runtime > API/Runtime/SignalProcessing

TAutoSlidingWindow enables use of a sliding window within a range-based for loop.

Example:

void ProcessAudio(TSlidingBuffer& SlidingBuffer, const TArray& NewSamples) { TArray WindowData; TAutoSlidingWindow SlidingWindow(SlidingBuffer, NewSamples, WindowData);

for (TArray& Window : SlidingWindow) { ... audio processing on single window here } }

int main() { int32 NumWindowSamples = 4; int32 NumHopSamples = 2; TSlidingBuffer SlidingBuffer(NumWindowSamples, NumHopSamples);

TArray Buffer1({1, 2, 3, 4, 5, 6, 7});

ProcessAudio(SlidingBuffer, Buffer1);

TArray Buffer2({8, 9, 10, 11});

ProcessAudio(SlidingBuffer, Buffer2); }
