The spectrogram is a plot of each segment’s FFT. The Frame Count parameter determines the number of FFTs the program uses to create the spectrogram and, as a result, the amount of the overall time signal that it splits into independent FFTs. For instance, it is possible to define a ...
the function you are using is the MathWorks' version of spectrogram, then you are plotting a complex-valued function. I don't really see the use case for wanting to do that. I can see wanting to plot the magnitude and phase separately, but that is not what plot(spectrogram(x)) is ...
The acquired data is sent to a computer and analyzed with Order Analysis software. Example of Order analysis results of a running machine. Left figure: a spectrogram of vibration values for the first 10 harmonic orders, measured between 1000 rpm and 3000 rpm. Right figure: extracted values for...

This completes our Chapter 9 of the Tutorial. That is nine very thorough chapters in a short 4.5 months. Chapter 10 is on the topic of Gases and is scheduled for release sometime in March of 2025. We have some other odds and ends to attend before resuming work on the Tutorial....
B. Spectrogram of the second giggle note from the bout for Ursa shown in the lower panel. The fundamental frequency is underlined in black. From this time varying fundamental frequency, we extracted the mean, the minimum and maximum values as well as the coefficient of variation (CV). The ...
There is a "Remove IR delays" button to remove the estimated IR delay from all selected measurements which have an IR Spectrogram and Waterfall Generation of waterfalls has ben made faster on system with multiple processor cores. There are also a few new features in the spectrogram and waterfall...
The next picture shows a relatively quiet room analyzed with myamalyzertool. This tool simply records audio coming from your standard microphone. It shows a spectrum on top of a piano keyboard. In addition there is aspectrogramunderneeth that shows energy over time (the area with the black ...
It's has been too long but ObsPy 1.1.0 has finally arrived! It is a pretty big release accumulating changes across the code base by 37 unique contributors over the course of over 20 months! Thanks a lot to everyone involved - it would not be possible without your help!
or is it a pure note, like when you strike a tuning fork? to find out, i viewed the above plot as a frequency plot. (mathematically, this is known as taking the fourier transform, and i've written more about that here ). if you haven't seen these spectrograms before, they're a...
