Hi Taylor,
The error occurred because “corrcoef” expects numerical value of the signals and you were passing the filenames as string. “corrcoef” returns a 2x2 matrix which has ones on the diagonal and correlation coefficients on the off-diagonal elements. You can use “audioread” function to load the audio sample into numeric matrices.
% Read audio files
[orig, fs_orig] = audioread('Machine_Gun_Burst.wav');
[synth, fs_synth] = audioread('Dry_Synthesized_Machine_Gun_Burst.wav');
% Compute Pearson correlation coefficient
correlation_matrix = corrcoef(orig, synth);
r = correlation_matrix(1, 2); % Off-diagonal element
You can refer to the documentation to gain more information about “corrcoef” by following the below link:
