soundscapecode

Python implemention of the soundscapecode, for analysing ecoacoustic soundscapes.

See the paper. This implementation is ported from a Matlab example.

Additionally, two sub-modules are provided:

• soundscapecode.soundtrap contains utilities for working with data from soundtrap hydrophones.

• soundscapecode.filters contains a highpass and bandpass filter compatible with Matlab filters of the same names.

Installation and Usage

pip install soundscapecode

Values can be calculated individually:

import soundscapecode as ssc

fs = 48000
mock_sound = np.random.rand(fs*60, 1)
periodicity = ssc.periodicity(mock_sound, fs)

Or to calculate all values for one recording:

from soundscapecode import SoundscapeCode

fs = 48000
n_mins = 3
mock_sound = np.random.rand(fs*n_mins*60, 1)
soundscape = SoundscapeCode(mock_sound, fs)
for dt in soundscape["dt"]:
    print(dt)

SoundscapeCode(sound, fs[, freq_range])	Wrapper for segmenting and calculating soundscape code metrics for a sound.
soundtrap.CalibrationData(serial, device, ...)	Holds soundtrap calibration information

max_spl(data[, reference_sound_pressure])	Calculates the maximum instantaneous sound pressure level for sound data.
rms_spl(data, fs[, reference_sound_pressure])	Calculates the root-mean-squared sound pressure level for sound data.
periodicity(data, fs)	Calculates the periodicity for sound data.
kurtosis(data)	Calculates the kurtosis for sound data.
temporal_dissimilarity(data_a, data_b)	Calculates the temporal dissimilarity between two sounds.
spectral_dissimilarity(m_freq_a, m_freq_b)	Calculates the spectral dissimilarity between two mean frequency inputs.
dissimilarity_index(data_a, data_b, ...)	Calculates the dissimilarity index between two sounds and the mean frequency inputs of the sounds.
soundtrap.soundtrap_conversion(signal, soundtrap)	Convert raw soundtrap values to uPa
soundtrap.get_soundtrap_calibration(serial)	Retrieve soundtrap information from OceanInstruments and save to output path
soundtrap.read_calibration(file_path)	Read soundtrap calibration information from file
soundtrap.open_wav(input_file[, channel, ...])	Open a wave file
filters.highpass(data, passband, fs[, ...])	Filter data with a highpass filter
