To efficiently tackle large datasets, MANTA is designed around a parallel-processing Matlab package, Raven-X (Dugan et. al., 2014, 2016, and 2018) that uses ordinary multi-core computers to accelerate processing speeds. MANTA calculates the sound pressure spectral density (PSD) levels in units of 1 µPa^2/Hz using Welch's Method in Matlab. The Discrete Fourier Transform length is equal to the sample rate, a Hann window of equal length is applied to the data and 50% overlap is used. This results in PSD estimates of mean-square pressure amplitude (µPa^2) with a frequency resolution of 1 Hz and temporal resolution of 1 second. The 120 PSD estimates from each 1-minute segment were averaged, and the average spectrum for each minute was further processed to a hybrid millidecade (HMD) spectrum as dB re 1 µPa^2/Hz, as defined in Martin et al. (2021b). Hybrid millidecades are an efficient means of storing PSD spectra from high sample rate audio files using 1-Hz values up to 435 Hz, then millidecade wide PSD values up to one half of the sampling rate (Martin et al., 2021b). The MANTA outputs for each day are: (1) CSV of the 1 minute HMD results; (2) image of the daily long-term spectral average based on the 1 minute HMD results, (3) image of the daily spectral probability density with percentiles, and (4) NetCDF containing products 2 and 3 in addition to a deployment-level MANTA Metadata output file containing the associated frequency-dependent calibration data used to compute the calibrated spectrum levels (Martin et al., 2021a, https://doi.org/10.1121/10.0003324; Martin et al, 2021b, https://doi.org/10.1121/10.0005818). asNeeded Based on the NCEI Metadata Template v1.2
