DATA GATHERING & ANALYSIS - Jack Wei

After the decision was made on what algorithm was to be used for the analysis of the musical input, work was commenced on the analysis of the basic sounds that the system would be expected to analyze. At first, the project group did not have access to any real musical instruments, so it was decided that MIDI files would be used. Using Winamp, wave files of each note that the system has to detect was created and anaylzed in MATLAB. Using the max (x) function of MATLAB in a max find algorithm, the amplitudes and locations of these peaks for each note were discovered and recorded for use in the recognition of input musical notes.
