Analysis

Various analysis protocols and standards for recorded underwater noise from ships.

Core processing and analysis

Spectrogram(data[, time, start_time, ...])	Handling of spectrogram data, both linear and banded.
SpectralProbability(data[, levels, ...])	Handles spectral probability data.
SpectralProbabilitySeries(data[, levels, ...])	Handling of spectral probability series data.
ShipLevel(data[, attrs])	Calculates and stores measured ship levels.

Helper functions and conversions

convert_to_radiated_noise(source, source_depth)	Convert a monopole source level to a radiated noise level.
level_uncertainty(averaging_time, bandwidth)	Compute the level uncertainty for a specific averaging time and frequency bandwidth.
required_averaging(level_uncertainty, bandwidth)	Compute the required averaging time to obtain a certain uncertainty in levels.
