MATLAB: How can I encrypt audio file or signal using xor

Question

Processes involves, inputing audio on matlab, converting it to binary form (matrix) then encrypting using XOR (probably an otp)

Answer 1

Use the 'uint8' option of getaudiodata(): you can xor against that.

repmat() your key as many times as you need to be exactly as long as your binary signal, and then you can xor on that.
