Original Abstract Submitted
an audio transmission is received by a participant computing device. the participant computing device is one of a plurality of participant computing devices of a participant cohort that are co-located. matched filters are generated based on the transmission that are configured to predict at least a portion of audio caused by playback of the transmitted audio signal. each of the matched filters includes coefficients. an audio signal is captured with an audio capture device. the captured audio signal corresponds to audio produced by playback of the transmitted audio signal with audio output devices of devices of the participant cohort. a matched filter is identified that most accurately predicts the audio signal. a delay estimate is generated based on a predictive contribution of one of the coefficients of the matched filter.
