If 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...
a conventional spectrogram doesn’t have a time axis. It shows a single balance of frequencies, averaged over a time period. However, if we keep this time period short, we can continually update
Below, two spectrograms show the difference between frequency spectra and order spectra, both over a speed range. In the frequency domain, the rotation-related energy components create trace lines across frequencies based on the related speed. On the other hand, structural dynamic energy components...
How does MDAQS work? Ideally, an instrumental audio quality assessment system should replicate human test subjects’ perceptions. MDAQS does this by analyzing binaural recordings of a specific stimulus file played back through the device under test (DUT). This file consists of uncompressed, high-re...
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....
iStumbler–iStumbler is another WiFi explorer/analyzer app that claims to be the “Leading wireless discovery tool for macOS”. We’re not sure about the claims here, but it does come with some excellent features that make it a decent alternative to the apps above. It can 3D map areas with...

Step 3. Once the frequency is displayed on the interface, look at the top of the spectrogram to check the bitrate. For example, when the frequency ranges to 22kHz, the music file can be a 320Kbps MP3 or lossless file. More Information About Bitrate in Audio Files For more information ab...
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 graphs: Airy and Morlet continuous wavelet transform modes have been added to the spectrogram graph ...
