AES Convention 121 · Paper 6906 · October 2006

Abstract

This paper describes the audio system software for portable audio players with respect to software and System-on-a-chip (SoC) architecture. The software system for portable devices includes audio playback, radio application, audio record, movie playback, image viewer applications. In addition, the portable systems can contain gaming and navigation applications. The portable audio players demand low-power and small form-factors differentiated by wide array of audio effects like equalizer, Time Scale Modification (TSM), and cross-fade. SoC plays a critical role in determining audio quality, audio features, power efficiency, battery life, form-factor, time to market and cost.
