Windowing an audio signal. In signal processing, a "window" is a function (shape) that is nonzero for some period of time, and zero before and after that period. When multiplied by another signal, it produces an output of 0 except during the nonzero portion of the window, when it exposes the other signal. The simplest example is a rectangular ...

https://wiki.aalto.fi/display/ITSP/Windowing
Windowing is a classical method in signal processing and it refers to splitting the input signal into temporal segments. The borders of segments are then visible as discontinuities, which are incongruent with the real-world signal. To reduce the impact of segmenting on the statistical properties of the signal, we apply windowing to the temporal ...

Tried using flush() but didn't work out. So, I decided to window the signal using a Hanning window but couldn't succeed in it either. To be very clear, I need to break an audio signal into 39 channels, rectify it (half wave) and then pass it into a second bank of 4th order filters, this time into 10 channels.
Effect of Windowing | Spectral Audio Signal Processing

Effect of Windowing. Let's look at a simple example of windowing to demonstrate what happens when we turn an infinite-duration signal into a finite-duration signal through windowing. We begin with a sampled complex sinusoid : (6.14) A portion of the real part, , is plotted in Fig. 5.3.

Answers (1) numFrames=floor (m/w_length); is wrong. Suppose your signal length is 160 and your frame length is 128 like you show, then floor (160/128) would be 1, but clearly there should be 2 frames. Sign in to answer this question.

Although performing an FFT on a signal can provide great insight, it is important to know the limitations of the FFT and how to improve the signal clarity using windowing. a. What Is Windowing When you use the FFT to measure the frequency component of a signal, you are basing the analysis on a finite set of data.
