SESSION 5: DSP IN LOUDSPEAKERS - PART 1 Towards the All-Digital Audio/Acoustic Chain: Challenges and Solutions Nicolas-Alexander Tatlas, Andreas Floros, Panagiotis Hatziantoniou and John Mourjopoulos University of Patras, Patras, Greece The obvious advantages of digital audio technology have up to now being manifested mainly in media storage and processing sub-components, which are parts of a more elaborate audio/acoustic analog reproduction chain. It is envisaged that the remaining components such as interconnects, amplifiers, and transducers will also soon be implemented in digital form, potentially leading to networked, integrated and highly optimized solutions. This paper examines theoretical and implementation aspects related to each of the modules that could constitute such an all-digital audio/acoustic transducer, namely: (a) the digital wireless receiver, examining the Bluetooth and IEEE 802.11 protocols; (b) audio decoding and format adaptation; (c) DSP for acoustic compensation, based on measured results for smoothed response equalization; (d) digital amplification; and (e) all-digital transduction.
