Biological activity
Inspect recurring calls, choruses, clicks and other biological acoustic events.
Biological, environmental and human-made sound
Understand how an underwater acoustic environment changes.
Explore long recordings with spectrogram, calibrated level and detection tools, then relate acoustic patterns to time, position, depth and water-column conditions.
From recordings to patterns
Keep sound sources and environmental context together.
An underwater soundscape can contain biological activity, weather, vessels, machinery and other sources that overlap in time and frequency. Analyze provides complementary views for separating and documenting those patterns.
Explore time and frequency
Navigate waveform, FFT and spectrogram views; listen to selected regions; and compare recurring tonal, broadband and impulsive features.
Measure acoustic levels
Use recorder and hydrophone calibration information to interpret SPL and frequency-dependent results where the required metadata is available.
Add project context
Relate observations to GPS tracks, CTD profiles, deployment depth and propagation scenarios rather than treating each recording as an isolated file.
Soundscape questions
Compare the sources and conditions shaping a site.
Vessel contribution
Compare broadband and tonal vessel sound with time-aligned position or operational records.
Ambient conditions
Review changes in background level and spectral character across recording periods.
Human-made sources
Document continuous machinery sound, construction activity and impulsive events.
Environmental context
Compare acoustic observations with depth, temperature, salinity and propagation conditions.
Annotated evidence
Save reviewed events, clips, plots, spectrogram views and structured tables for reporting.
A repeatable workflow
Describe change without losing the underlying evidence.
Organise
Group deployment files, calibration details, positions and environmental data within the project.
Inspect and annotate
Find acoustic features manually or with model assistance, then review and classify the events that support the interpretation.
Compare and export
Retain consistent images, clips, measurements and tables so differences between periods or locations can be reviewed and reported.
