Why overlap STFT?

Due to the speed of FFT convolution, the STFT provides the most efficient single-CPU implementation engine for most FIR filters encountered in audio signal processing. . Due to this filtering, the frames must overlap, even when the rectangular window is used.

What is overlapping in signal processing?

Overlapping of signals happens when signals from two or more than two origins are broadcast at an equal frequency.

What is a 50% overlapping technique?

A technique utilized while applying a polish or protection where each pass overlaps the previous pass by 50% to ensure thorough application.

Why do we use overlap in FFT?

FFT processing can be particularly problematic when the signal consists of randomly occurring transients superimposed on a more continuous signal. Overlap processing is commonly used in this situation to improve the estimates.
