This paper aims at providing a broad overview of the status of audio support in mobile hand-held devices. The evolution from audio players or cell-phones into convergent devices supporting multiple and complex use-cases has generated new system constraints and new mobile audio architectures. By reviewing the complete mobile audio framework, from codecs to audio middleware, from platform architecture to hardware, we provide a down-to-earth explanation for critical and dimensioning factors and shed some light on existing standards, upcoming solutions and needed compromises.
