Question $3$: Sound Effects $[30$ marks$]$

Many different effects can be used to transform audio. You are required to implement a simple reversing algorithm. Write a MIPS program, called question$3.$asm, that will read in a WAVE file, and will then reverse the audio data in the file, and output this to a new file. You will need to

obtain, from the user, the full input file name $($the entire path$),$ the full output file name $($the entire path$)$ and the file size $($in bytes$).$ You may assume that all audio files inputted will only have $1$ channel and will have a bit depth of $16.$

Note: for this question, the Automarker will not check your console output $($and there should not be console output, only input$).$ It will only check your output file. When it prints your output file, it will convert your binary file to a textual hexadecimal form.

Sample Console Input:

$/$home$/$lynn$/$Documents$/$CSC$2002$S$/$assign$1/$q$3\_$t$1\_$in$.$wav

$/$home$/$lynn$/$Documents$/$CSC$2002$S$/$assign$1/$q$3\_$t$1\_$out.wav

$64$
