I am trying to compare the build-in function gtcc() and extract() for extracting the GTCC features of an audio
By using gtcc function as:
features_gtcc = gtcc(x,fs,"LogEnergy","ignore");
and using extract as:
extractor = audioFeatureExtractor("SampleRate",fs, ...
"Window",hamming(round(0.03*fs),"periodic"), ... % Defalt overlap and window size for gtcc function
"OverlapLength",round(0.02*fs), ...
"gtcc",true);
features_extract = extract(extractor,x);
Two results are different.
Could anyone tell me why is that please?
