Assume that you want to analyze the audio containing just the last guitar accord before the singer comes in$.$ Build a script $($lab$\_1$B$.$m$)$ using a FOR LOOP that builds a signal x$[$n$]$ that contains just the samples in the interval $[17000,19000]$ of song; i$.$e$.,$ the script should create x$[$n$]$ that satisfies:

x$[0]=$ song$[17000]$;

x$[1]=$ song$[17001]$;

$...$

x$[2000]=$ song$[19000]$;

Then execute the script:

$>>$ lab$\_1$B
