Windowing is most often used in spectral analysis, to view a short time segment of a longer signal and analyze its frequency content. Windows are also used to create short sound segments of a few milliseconds’ duration called “grains”, which can be combined into granular sound clouds for unique sorts of synthesis.

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.

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.

a technique called windowing. Windowing reduces the amplitude of the discontinuities at the boundaries of each finite sequence acquired by the digitizer. Windowing consists of multiplying the time record by a finite-length window with an amplitude that varies smoothly and gradually toward zero at the edges.
choosing windowing function for audio signal processing
https://dsp.stackexchange.com/questions/13213/choosing-windowing-function-for-audio-signal-processing
Show activity on this post. Currently I am working on chord recognition, and get confused on several aspect. One of them is choosing windowing for reduce the spectral leakage. from what I read, hanning/hamming function is a good choice for windowing, but currently I read about welch windowing function, and its quite good either.
2.3.11 Windowing Functions to Eliminate Spectral Leakage ...
https://digitalsoundandmusic.com/2-3-11-windowing-functions-to-eliminate-spectral-leakage/
In addition to choosing the FFT window size, audio processing programs often let you choose from a number of windowing functions. The purpose of an FFT windowing function is to smooth out the discontinuities that result from applying the FFT to segments (i.e., windows) of audio data. A simplifying assumption for the FFT is that each windowed segment of audio data contains …
2.3.10 Windowing the FFT – Digital Sound & Music
https://digitalsoundandmusic.com/2-3-10-windowing-the-fft/
The FFT window size is typically a power of 2. If your sampling rate is 44,100 samples per second, then a window size of 32 samples is about 0.0007 s, and a window size of 65536 is about 1.486 s. There’s a tradeoff in the choice of window size. A small window focuses on the frequencies present in the sound over a short period of time.
DSP; Framing and Windowing in Audio Signal Processing
https://www.dsprelated.com/thread/6293/dsp-framing-and-windowing-in-audio-signal-processing
I am trying to make a synthesis signal from my audio data (pitch shift my audio) by delay-line method. As I know, the implementation of delay-line method is going on the time domain processing. My question is, should I framing and windowing My audio data before trying to pitch shifting it? Thank You, Sir
