I have a doubt in wolfram mathematica
. What happens is that I have an array of data and I can generate a espectrograma
, what I need is to generate this same spectrogram in 3 dimensions,
2D spectrogram
3D spectrogram (what I want to obtain)
What I want is to achieve something like in the following image
I have achieved it with files .WAV
but not with an excel column with data, which I import into mathematica, I only managed to apply filters and do the spectrograma
2D. If someone could give me some help I would appreciate it. Thank you very much.
Edit (I'll add what I have regarding the doubt)
I am using the code that is in the following link, but I think I do not understand the input parameters for the function well, I cannot get it to work for the .csv file . It is probable that I am doing everything wrong and this is not the function that I should use, I have also tried with ListPointPlot3D without results (I can only graph the spectrogram in 2D), but here they import a .WAV file

Attached is the link of the noise.scv file (file of values separated by commas) which is the one I need to graph

And finally the lines of code to import the file to Wolfram
datosExcel = Import["C:\\ruta_del_archivo.csv"]
datosExcel = datosExcel[[All, 1]]
