Underwater acoustic analysis, in one project workspace

From raw WAV to defensible acoustic evidence.

Analyze connects recordings, calibrated SPL, spectrograms, GPS tracks, CTD profiles and propagation models—so the context stays with the signal from first inspection to final export.

A connected analysis platform

Purpose-built for acoustic work, not adapted to it.

Work with the same files and metadata across every tool. Channel settings, hydrophone calibration, timing and project outputs remain available as the analysis moves forward.

01

Waveform & FFT

Inspect multi-channel recordings, measure selected regions, find peaks and compare time- and frequency-domain evidence.

VRMS · peak labels · calibrated SPL
02

Spectrogram & playback

Navigate long recordings fluidly, listen at adjustable speed, search for signals and export selected views, clips or video.

Live cursor · region export · colour scale
03

Chart & GPS

Place acoustic results in time and space using imported tracks, stationary sources, bathymetry and project observations.

Aerial charts · tracks · event timing
04

Propagation modelling

Compare bottom types and sea states, apply detection thresholds and align model output with tracks and CTD data.

Corridors · scenarios · depth context
05

SPL & records

Review calibrated measurements, explore multi-frequency results and carry selected evidence into consistent tables and plots.

Frequency bands · plots · exports
06

DIFAR & detection

Process directional data, test scenarios with the simulator and use detection tools to isolate acoustic events at scale.

Bearings · simulation · event tools

See the work, not a mock-up

Move through the project without losing your place.

Each workspace is designed around the same practical task: understand what happened in the recording, retain the supporting context and make the next action obvious.

Spectrogram

Play, search and select acoustic events while the visible time and frequency ranges update in place.

Chart & GPS

See the track in one complete chart.

The chart workspace places project GPS data on a single, fully rendered Aerial base map. Optional DIFAR, propagation, bathymetry, waypoint and CTD layers can then be added when the analysis calls for them.

Field-to-report workflow

A clear path through complex data.

  1. 01

    Import & configure

    Open recordings, assign channels and calibration, and attach the GPS, CTD or project data that provides context.

  2. 02

    Inspect & measure

    Use waveform, FFT and spectrogram views to locate events, examine frequency content and capture repeatable measurements.

  3. 03

    Calibrate & model

    Convert voltage measurements where required, compare environmental cases and connect source or receive levels to position.

  4. 04

    Review & export

    Check outputs in project tables, retain images and clips, and export organised datasets for reporting or further analysis.

Analyze · Propagation Modelling
Analyze propagation modelling results with environmental scenario controls

Propagation with operational context

Model where the sound travelled—and when.

Build comparisons from analysed recordings or entered SPL and frequency values. Then connect the result to the conditions, depths and positions that shaped it.

  • Compare selected bottom type and sea-state combinations
  • Use focus-frequency or full-band range criteria
  • Apply a minimum receive level for detection
  • Use CTD profiles and deployed source or hydrophone depths
  • Align time-varying pings or LFM levels with GPS tracks

Outputs that stay organised

Evidence belongs with the project that produced it.

Project-scoped folders

Images, clips, video, tables and model exports are saved beneath the selected project instead of disappearing into unrelated locations.

Useful export choices

Save the view that supports the finding—from labelled FFT plots and spectrogram video to scenario-separated modelling data.

Repeatable workflows

Use project workflows to track progress across large collections of WAV files and the tests, notes and outputs attached to them.

Detailed tool guide

Learn the method, not only the menu.

The current Analyze user manual covers project setup, interface controls, analysis tools, modelling workflows and the underlying methods used to interpret results.
