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

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.

Audio files do not require double / floating point to be played.
You read (most) audio files as integer instead of double by adding the option 'native' top audioreader()
You can pass uint8 data to audiowriter() and it will write them to the file.
You can play uint8 data with audioplayer()
