Digital signal processing (DSP) offers loudspeaker system designers a very powerful set of tools. It may be as simple as a delay line, which hardly needs DSP anyway. Or it may be a precise and detailed filtering with just the desired magnitude and phase characteristics. Such filtering may be used to construct a single very accurate loudspeaker, or used for room correction, or it may be used to create beam-steering arrays or even wavefield synthesis. In addition to filtering, digital signal processing may be used for distortion compensation, or for enhancing the subjective performance by means of nonlinear processing. On the analysis side, DSP can be used to monitor in real time the state of the loudspeaker and model important driver parameters such as voice coil temperature. Through the last couple of decades, AES members have been in the forefront of this research.

Meanwhile, the maturity and price/performance ratio of essential system components such as processors, software development tools, AD/DA converters, and power amplifiers have reached a point where it makes commercial sense for a large part of the audio industry to apply loudspeaker-specific DSP in their products. Indeed, there are already classes of products completely depending on it.

This international conference aims to present the state of the art within the rich and still emerging field of loudspeakerspecific DSP and create an inspiring and synergetic meeting between professionals in the fields of electroacoustics, psychoacoustics, room acoustics, transducer physics, and DSP.
