Abstract

Every day more applications for smartphone devices are being developed – on Android, iOS, Windows Phone, as well as other platforms. Mobile devices are being used for a rising number of everyday tasks, and as such convenient gadgets they are showing great market potential. This article is following the development of an application for sound editing on an Android mobile platform and deals with a simple analysis of an audio signal's amplitude-time domain. It implements three simple functions for signal processing and recorded sample visualisation. The graphic interface, without which the control of this application would not be possible, is also being discussed, along with some basics of digital sound analysis.
