Purpose For my final project I am going to use the SDRAM. I am uploading 9 files that exceed the limit of the internal memory RAM. I am going to manipulate the output so that a maximum of three files can be output together . Three files where going to be guitar tracks, other three bass files and the remaining three drums files

Unformatted text preview: which will be the size of the array buffers we will need for the files to be stored in the SDRAM Instrument Array Buffers We had to tell the compiler that we were going to store the array in the section of the SDRAM called “mySDRAM” also declaring the array with the size of the number of samples obtained from the conversion back in MATLAB. Since I was uploading 9 files I had to create 9 arrays GEL Files For my project I created 6 slider GEL files. Three of them are the volumes of each instruments and have a range from 0 to a hundred. The remaining three are sliders that changes the track of each instruments and they have a range from 0 to 4 Outputting three files To make this happen I created a series of if and else if statements for each instrument that would result in adding to the output...
