Hello!
I´m trying to figure out how to get similarity of two audio signals in LabVIEW.
I read original signal from WAV file and I do some operations with it (filtering etc.). After that I want to know similarity of original and filtered signal(spectrogram).
I know about two things: correlation and cepstrum distance(don´t know how to implement).
I have tried LabVIEW CrossCorrelation.vi file to compare my two signals spectrograms, but I´m not sure how to evaluate the result (Check picture).
I get some kind of graphic information, but how can I evaluate it statistically? For example: Output is 80% similar to input....
Can you show me any direction, or give any advice?
I have LabVIEW 2013
I have also attached my VI + source WAV signal.
