12. Digital Audio: Sequencing Audio Using SoundPool

Digital audio is a bit different from digital imagery and digital video as you can't see it; you have to rely on your ears. Instead of using waves of light, as color does, digital audio uses waves of sound, and as such, the technical fundamentals are completely different. If you are new to digital audio, part of this chapter will cover the theory and the concepts behind digital audio, as well as the plethora of digital audio codecs, that is, audio file formats, which are supported in Android, as well as what each of them will be used for inside of an Android application.
