What is a spectrogram and how do I set its parameters? The spectrogram is a 2D visual heat map where the horizontal axis represents the time of the signal and the vertical axis represents the frequency axis What is visualized is an image where darker colours means that for a particular time point and a particular frequency, the lower in magnitude the frequency component is, the darker the colour
Signal Processing: Can someone explain for me the different type of . . . Spectrogram: Splitting a sound into harmonics A spectrogram is a visualization of the frequency spectrum, a breakdown of the sound into pure sinusoids of different frequencies A spectrogram provides a view of how the amplitude of the different frequencies vary according to time
fft - Spectrogram C++ library - Stack Overflow Audacity includes spectrogram source code; glfer includes waterfall spectrum display spectrum source code; source code that uses fftw to compute the spectrogram of an audio stream; more source code that uses OpenAL and fftw to compute the spectrogram for an audio stream "Sound Activated Recorder with Spectrogram in C#" by Jeff Morton
Phase information of a signal when creating a spectrogram Fourier transforms are used to create spectrograms (I understand the vanilla DFT) They allow us to see the different frequencies that make up a signal, and with this knowledge we can plot create an amplitude spectrogram During this process, phase information is discarded Correct?
Python spectrogram in 3D (like matlabs spectrogram function) I have all the values that I need for a spectrogram (scipy fftpack fft) I would like to create a 3D spectrogram in python In MATLAB this is a very simple task, while in python it seems much more complicated I tried mayavi, 3D plotting matplotlib but I have not managed to do this Thanks
