When I use the "audioFeatureExtractor" to extract MFCC, since there are 13 MFCC features, I am not sure how to use the setExtractorParams function to pick specific MFCC features? For example, MFCC 1, 4 , 6, and 11.
aFE = audioFeatureExtractor("SampleRate",fs, ...
"mfcc",true);
idx = info(aFE) % output below.
setExtractorParams(aFE,"mfcc",) % not sure how to pick the MFCC features. I don't need all of them.
idx = struct with fields:
mfcc: [1 2 3 4 5 6 7 8 9 10 11 12 13]

Hi Ibrahim,
Here you go:
setExtractorParams(aFE,"mfcc","NumCoeffs",11)
