I am using Matlab 2018b
[audioIn,fs] = audioread("C:\Users\mooma\Desktop\Audio_Speech_Actors_01-24\Actor_01\1.wav");
aFE = audioFeatureExtractor( "SampleRate",fs,"Window",hamming(round(0.03*fs),"periodic"), "OverlapLength",round(0.02*fs),"mfcc",true);
features = extract(aFE,audioIn);
idx = info(aFE);
Whenever I run this code, an error comes as Undefined function or variable 'audioFeatureExtractor'
Can anyone help me with this . I have to submit project next week.
