Signal = audioread(FileName);

This imports the audio signal as matrix. I assume you require it in an integer format for the bit access. If Signal has the double format, use e.g.:

SignalInt = uint16(Signal * intmax('uint16'));

The embedding of the data cannot be answered in general. Please explain, what you want to do with details.
