Butunlessyou’vestudiedelectricalormechanicalengineering,youprobably

haven’thadachancetolearnaboutsignalprocessing.Theproblemisthatmost

books(andtheclassesthatusethem)presentthematerialbottom-up,starting

withmathematicalabstractionslikephasors.Andtheytendtobetheoretical,

withfewapplicationsandlittleapparentrelevance.

Thepremiseofthisbookisthatifyouknowhowtoprogram,youcanusethat

skilltolearnotherthings,andhavefundoingit.

Withaprogramming-basedapproach,Icanpresentthemostimportantideas

rightaway.Bytheendofthefirstchapter,you’llbeabletoanalyzesound

recordingsandothersignals,andgeneratenewsounds.Eachchapterintroduces
