    • Unknown Impulse Detection Events Recorded at SanctSound Site HI06_02

    Metadata Updated: June 16, 2023

    This record represents the unknown impulses detected from raw passive acoustic data. All acoustic data were processed using Triton's Explosion Detector, which is based on a cross-correlation of the recording with a template explosion. The detector divides the recording into sequentially analyzed sections of 75 s. The detector outputs are a series of .mat files that can be evaluated using GPLReview. The original wav file was decimated to a sample rate of 12 kHz, a requirement of the algorithm. The default parameters work well for most explosive sounds. These data were recorded at SanctSound Site HI06_02 between November 30, 2020 and May 12, 2021.
