How can I add vggish features to the array?

1 次查看(过去 30 天)
Hi. I have about 5k of .wav files and want to pass them through vggishFeatures. Then I would like to add every feature to the array, this array to .csv or something and use it in Python. Sizes of these features are not fixed so there's another problem with it for me. Any ideas how can I perform it? Did it as below, but doesn't work as it should:
label = [];
ficz = [];
for k = 1 : length(theFiles)
baseFileName = theFiles(k).name;
fullFileName = fullfile(theFiles(k).folder, baseFileName);
% read audio and get feats
[audioIn,fs] = audioread(fullFileName);
featureVectors = vggishFeatures(audioIn,fs);
fV = featureVectors(:)
ficz(:,end+1) = fV;

As per my understanding, you want to write variable size arrays (feature vectors) to a CSV file. You can do the same as follows:-
ficz = [];
for k = 1:length(theFiles)
%---Your Code Here---%
ficz{end+1} = fV;
