Software applications and programming languages are available to assist audio DSP algorithm developers and mobile device designers, including Matlab / Simulink, C/C++ and assembly languages. These tools provide some assistance for algorithmic experimentation and subsequent refinement to efficient embedded software. However, a typical design flow is still highly iterative, with manual software recoding, translation and optimization. This paper introduces software libraries and design techniques that integrate existing commercial audio algorithm design tools and permit intuitive algorithmic experimentation and automated translation of audio algorithms to efficient embedded software. These techniques have been incorporated into a new software framework and the operation of this framework is described using the example of a custom audio coding algorithm targeted to a mobile audio device.
