Hello Friend,

I would like some help to generate a .wav file so that we can compare it with my database built with Audacity software with 16bits-PCM. We started using a function:

fs = 44100; % of sample frequency
nobits = 16; % of bits per sample
nochannels = 1; % of channels (mono)
recording = audiorecorder (fs, nobits, nochannels);
get (recording);
recording = audiorecorder;
disp ('Start talking').
recording (recording, 5);
disp ('End of Recording');

But I do not have a hit rate on my neural network, when recording with Audacity and then loading audio with "audioread" and inserting into the neural network, it gives me a high hit rate. However when recording directly by audiorecorder in Matlab, it is not possible to perform matches. Any suggestions?
