3. Audie collage. Create a library to manipolate dipital audio and use that literary to create an ausio collage. As in lecture, we will ropresent sound as ant arry of real numbers between 1 asd +1, with 44,100 samples per second. You will write a library of functions so prodace wobio effecti by manipulatise such amayk. - Anpinfr. Create a ncw sokad that contains the same samples as an custing sound, but with cach saniple multiplied by a constant . This increases the volume when >1 and electeases it w fien 00, with sample i of the new soard haviat the same amplitude as sampie li a j of the existing sound. To do so, orgatias your peogratn aceonding to the follow ing public AII. publie elass Audiocedange f pubdie statie destblef anplify(double(1 a, double alphe) public statie deablej reverse(doublell a) publie atatie dowblo|l nerge(doubloll a, double11 b) publie thatie deublell mix (deublell a, dooblell b) pubise statio decblell changespeed (doublell a, double alpha) publie statie veid ain (suribgil args) ) Here is some more information ahout the required behavior: - The functions mat met mutate the argumeni artay(s). - Yow aay assume that the arroy arguments are not aud1 and that a>0 in ehangetpeodi. - The matn () method mast create an asabio collage and play it using Sedoudio.play (.). - Do not ase any command-line anguments. - The duration must be between 10 and 40 seconds (44),000 so 2,646,000 samples). - All samples sent bo standard audio mast be between 1 and +1. - It must use at Ieast five different WaY files.
