Multichannel WAV
Select, label and compare hydrophone, voltage and directional channels.
Hydrophone data analysis software
Turn hydrophone WAV files into calibrated acoustic evidence.
Analyze combines multichannel waveform inspection, FFT, responsive spectrogram playback, hydrophone sensitivity data, SPL measurements, event detection and organised exports in one project workspace.
One continuous workflow
From raw voltage to interpretable sound levels.
Open uncompressed WAV recordings, choose the active channels and retain channel-specific calibration and metadata as the recording moves through the analysis tools.
Inspect the signal
Scroll through time, adjust the displayed window, select regions, take measurements and compare channels without losing the relationship to the original recording.
Analyse frequency content
Use FFT and spectrogram views to examine dominant frequencies, tonal components, broadband noise and transient events. Peak labels and saved views preserve the evidence used in review.
Calculate calibrated SPL
Where voltage recordings require calibration, assign hydrophone sensitivity information to the channel and report sound pressure level in dB re 1 µPa. Raw voltage and calibrated results remain distinguishable.
Core capabilities
Tools designed around underwater recordings.
Waveform and FFT
Measure regions, find spectral peaks and export labelled graphs.
Spectrogram playback
Play, scroll, search, select clips and export views or audio-backed video.
Hydrophone calibration
Associate sensitivity curves with channels when conversion from voltage is required.
Detection and search
Locate pulses, tonal signals and custom frequency-dependent profiles.
Project exports
Keep CSV, images, clips, video and model output beneath the selected project.
Common questions
Hydrophone analysis FAQ
What hydrophone files can Analyze process?
Analyze works with uncompressed WAV recordings, including multichannel files. Calibration and channel roles can be assigned within the project.
Can it analyse recordings that are already expressed as SPL?
Yes. Workflows can use analysed SPL results directly without applying a hydrophone sensitivity curve a second time.
Can results be connected to GPS and CTD data?
Yes. Project GPS tracks and CTD profiles can supply spatial and environmental context for charting and propagation modelling.
