  text: "Wireless Acoustic Sensor Networks (WASNs) have a wide range of audio signal
    processing applications. Due to the spatial diversity of the microphone and their
    relative position to the acoustic source, not all microphones are equally useful
    for subsequent audio signal processing tasks, nor do they all have the same wireless
    data transmission rates. Hence, a central task in WASNs is to balance a microphone’s
    estimated acoustic utility against its transmission delay, selecting a best-possible
    subset of microphones to record audio signals.\r\n\r\nIn this work, we use reinforcement
    learning to decide if a microphone should be used or switched off to maximize
    the acoustic quality at low transmission delays, while minimizing switching frequency.
    In experiments with moving sources in a simulated acoustic environment, our method
    outperforms naive baseline comparisons"
