Long-Term Acoustic Recordings from Australian Wet Eucalypt Forest

Featuring long-term environmental audio recordings from the Tumbarumba Wet Eucalypt SuperSite in Australia, established in 2000. Two acoustic recorders collected 12 hours of audio per day, split between dawn and dusk periods, starting in 2012. The data includes generated long-term spectrograms and sensor measurements of temperature and sound pressure levels.

Use Cases

• Identify bird chorus patterns by analyzing audio files recorded during dawn and dusk periods.
• Characterize the forest soundscape using long-term spectrograms generated for each audio file.
• Monitor environmental changes by correlating recorded temperature data with acoustic activity over time.
• Assess fauna biodiversity by detecting and classifying sound sources of interest within the audio recordings.

Strengths

• Recordings span from 2012, providing over a decade of long-term environmental audio data.
• Data collection is structured with 12 hours of recording per day, specifically targeting dawn and dusk choruses.
• Includes supplementary sensor data such as temperature and sound pressure levels alongside audio files.

Limitations

• The dataset's total size and number of audio files are unspecified, complicating download and storage planning.
• Recordings are limited to 12 hours per day, missing full 24-hour soundscape coverage.
• Geographic scope is restricted to a single 1-hectare plot in a specific Australian forest type.
