Recording review and QC
Inspect file structure, channels, clipping, timing, noise conditions and available metadata before analysis begins.
Expert acoustic analysis
Send the data. Receive an organised, reviewable result.
Blackfish Acoustics can analyse hydrophone recordings, PAM deployments, directional sensor data and sonar trials when your team needs additional capacity, a specialised method or a defensible project record.
Available services
Analysis shaped around the question—not a generic output.
Hydrophone and SPL analysis
Apply the supplied calibration method, calculate acoustic levels and retain the voltage and frequency evidence supporting the result.
PAM detection review
Search long deployments for biological or anthropogenic events, review candidates and prepare clips, tables and summary evidence.
DIFAR and directional data
Verify channel roles, process directional events, review bearings and map results against tracks or fixed positions.
Sonar and pulse trials
Analyse CW, LFM or HFM transmissions, pulse timing, received levels, frequency behaviour and time-varying trial results.
Propagation and mapping
Combine acoustic results with GPS, fixed sources, CTD profiles, deployment depths and environmental scenarios.
How a project works
Clear inputs, documented decisions and usable deliverables.
- Scope: define the acoustic question, required outputs, schedule and review criteria.
- Data check: examine representative files, channel definitions, calibration, timestamps, GPS and CTD exports.
- Analysis: perform the agreed workflow while retaining intermediate evidence and noting assumptions.
- Review: deliver results for client review and resolve agreed questions or corrections.
- Handover: provide the final report, data tables and organised supporting files.
Data can remain project-specific
The scope can cover a single difficult recording, a sonar trial, a multi-file PAM deployment or a repeatable batch-analysis workflow.
Typical deliverables
Results that can be checked and reused.
| Deliverable | Purpose |
|---|---|
| Analysis summary or technical report | Methods, assumptions, results, limitations and interpretation appropriate to the agreed scope. |
| CSV or workbook data | Measurements, detections, scenario comparisons and supporting values in an accessible table format. |
| Figures and maps | Labelled waveform, FFT, spectrogram, GPS, directional or propagation views suitable for review. |
| Selected acoustic clips | Time-bounded WAV evidence for candidate events or representative signals. |
| Project archive | Organised outputs connected to the source recordings and project context. |
| Repeatable workflow | Defined processing steps for applying the accepted method to additional files. |
Request a project scope
Tell us what was recorded and what decision the analysis must support.
Include the recording system, channel count, calibration information, approximate data volume, available GPS or CTD data and the output you need. A representative file is usually the fastest way to confirm the approach.
