Abstract: This paper presents collaboration approach results between an audio signal processing algorithm and a digital amplifier structure for efficient implementation of soundbar applications. If we want to provide a virtual surround sound image with a linear loudspeaker array, high performance DSP and multichannel digital amplifiers are required. The required performance for DSP is depended on the algorithm complexity for creating a virtual surround sound image. However the final computation before generating the output loudspeaker signals (e.g., 16 channels) is generally composed of simple delay and sum computations from an input audio signal (e.g., 5.1 channels) to output multichannel loudspeaker signals. Therefore we redesigned the audio signal processing software by two-block processing, and the second block for simple delay and sum computation is implemented at the multichannel digital amplifier, which has an independent DSP core. Through computational simulation and hardware implementation, the proposed system showed equivalent performance with the conventional one block processing system.
