This dataset contains audio files from Great Western Woodland SuperSite. The site was established in 2012 in Credo Conservation Park. The site is in semi-arid woodland and was operated as a pastoral lease from 1907 to 2007. The core 1Â ha plot is characterised by Eucalyptus salmonophloia (salmon gum), with Eucalyptus salubris, Eucalyptus transcontinentalis and Eucalyptus clelandiorum dominating other research plots. For additional site information, see Great Western Woodlands SuperSite
In 2020 four acoustic recorders were set up to collect audio data continuously as part of the Australian Acoustic Observatory (A2O) project. Two recorders were placed in relatively wet habitats and two in relatively dry habitats.

Purpose
Long-term acoustic recordings are collected to characterise the acoustic sources in the ecosystem. Recordings can be used to estimate biodiversity, monitor temporal changes in the soundscape, compare the acoustic characteristics of different locations, and assess the effect of particular events such as bushfires and floods.
Lineage
Four acoustic sensors are set up to collect audio data continuosly as part of the A2O project. Sensors are Frontier Labs Solar BAR. Each sensor has a Primo EM172 microphone with an 80Â dB signal-to-noise ratio, 14Â dBA self-noise, -28Â dB sensitivity, and a flat response (+2Â dB between 80Â Hz and 20Â kHz). Sensors have a gain of 50Â dB. They are mounted on 1.8Â m star pickets and powered by solar panels. Data are recorded continuously. Recordings are made as single channel, two-hour long flac files. They have a sampling rate of 22,050Â Hz and a depth of 16Â bits.
The four sensors are deployed in pairs. Each pair contains a wet and a dry sensor. Wet sensors are located within 50 m from the edge of a body of water. Dry sensors are located between 500 m and 5 km from their corresponding wet sensors. Wet–wet and dry–dry sensor points are at a distance between 500 m and 5 km.
