I am currently working on a set of .wav files which, unfortunately, do not have the same sampling rate - I need to resample them for the purpose of feeding them to a neural net.
So - using Sox I resampled every file - with the command:
sox -v 0.99 filein -G -r 192000 fileout
However, having a look at the resampled files: ,
the frequency range has changed. Which is confusing me. I have put several hours into finding out why this is happening but i can't seem to find the reason.
Can somebody explain?
EDIT1: Just realized that this example is misleading as I am referring to the change in maximum Frequency, (the y-labels)
