Besides the omnipresent mobile phones, we are surrounded by many recording devices such as laptop computers, tablets, smart watches, camcorders, and others. While many speech and audio applications have been traditionally implemented on compact devices featuring one or more microphones, wireless acoustic sensor networks (WASN) now offer a new paradigm for acoustic sensing and processing, bearing the promise to overcome the limitations of individual devices. The integration of WASNs in new speech and audio applications triggers a host of challenging research questions, solutions to which are at the core of this special issue.
This special issue invited authors to submit papers that demonstrate challenging research questions, methods and solutions for dealing with ad-hoc distributed microphone signals and applications thereof.
