![]() P = sin(2*pi*1*t1) %this represents a pause in the musicīelow is the MATLAB sound() function set up so that it plays the notes in order for the Star Spangled Banner. ![]() This is because during certain instances in the song, the same note needs to be held for different lengths of time. Notice that some notes are declared twice using different "t"s. Notice that t is multiplied by different numbers representing the different frequencies of all the notes. This section of the code sets the timing for the notes, each time represents what the length of a beat will be.īelow is the declarations for all of the notes I use in this song. ![]() Below is an example of MATLAB code that can be used to play the star spangled banner. Each note has certain frequency that corresponds to it and through sine waves and putting it into the sound function we are able to create a song. Using the sound function in Matlab, we are able to create a song using sine waves with specific frequencies. The lyrics come from 'Defence of Fort McHenry', a poem written on September 14, 1814. Coding the Star Spangled Banner in MATLAB 'The Star-Spangled Banner' is the national anthem of the United States.
