audioFeatureExtractor function not found
显示 更早的评论
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.

This function is introduced in R2019b.

If you are only interested in MFCC extraction, you can use the mfcc function, which Audio Toolbox introduced in R2018a. Here's how you would use it to accomplish the same thing as in your example:
[audioIn,fs] = audioread("C:\Users\mooma\Desktop\Audio_Speech_Actors_01-24\Actor_01\1.wav");
coeffs = mfcc(audioIn,fs);

Hello guys, I am using R2021b version. When I used this function 'audioFeatureExtractor', I met some error. Also, I have audio toolbox in MATLAB.
Error:
Unable to resolve the name
matlabshared.fusionutils.internal.setProperties.
Error in audioFeatureExtractor (line 385)
matlabshared.fusionutils.internal.setProperties(obj,length(varargin),varargin{:});
Can anyone help me?
