Performance Evaluation of an Audio Tuner System Based on AIR Audio Processing Library

In the development of applications for mobile devices that can be easily portable and lightweight, the language of the byte code, such as Action script is preferred. However, if you need a high speed, it is necessary to cooperate with software library written in C/C++. In its cooperation, buffer management, such as efficiency of binary data conversion, is still an important research topic. In this paper, we focus on the buffer management of spectrum analysis on mobile audio signal processing. And, we report the performance evaluation in cooperation with the Fourier transform C++ language library and Action script running on Adobe AIR.
