Inside the MFCC parameter configuration in Impulse Design, after I have imported my own data in the form of wav files, I get this error under the “DSP result”.
Using another preprocessing block, like spectral analysis, I don’t get any errors (which makes sense since this is a MFCC-specific error).
I received this error immediately while using the default values for MFCC. Changing some parameters at random seems to not change anything.
Anything else I need to tweak here? My data for sure contains a positive number of samples (since it is audio data I can listen to it), and I don’t understand why I am getting this message.
Another thing I noticed is that somehow my Raw Features box is empty, but when I add a Raw Data processing block the Raw Features will contain a number of samples. The Raw data graph shows a graph of my audio data in both cases.
