I've been trying to perform a cross-correlation analysis between a Middle C sound (C4) and C5. I'm using the software RavenPro by Cornell to do the analysis. However, I've been unable to see a spectrogram for the middle C waveform.
As you can see, the waveform is visible, but I'm unable to discern a spectrogram here. Is there any reason this could happen?
In comparison to this, I'm seeing a spectrogram for C5, as you can see below
I've attached the youtube link for the both the sounds in the file, do let me know if anyone could provide any insight on this.
