# Bat Survey Time Calculator

> Estimate the hours you'll spend analysing bat WAV recordings, with and without AI.

Last updated: 2026-04-25.

## The math

Based on real customer data (Wharton case study):

- **Traditional / Kaleidoscope-class workflow:** 495 hours per 2TB (247.5 hours per TB, 0.2475 hours per GB)
- **BioSonic workflow:** 168 hours per 2TB (84 hours per TB, 0.084 hours per GB)
- **Time saved:** 327 hours per 2TB (163.5 hours per TB)
- **Percentage saved:** 66%

## How it works

1. Enter your data volume (GB or TB)
2. Enter your hourly rate and currency
3. The calculator shows hours and money saved, with a visual bar chart

## Where the numbers come from

Wharton, a UK ecology consultancy, documented 327 hours saved per year on 2TB of recordings after switching to BioSonic. The time saving comes from:

- Eliminating manual 5-second file splitting
- Automated noise filtering (4M non-bat training samples)
- One-click report generation vs manual pivot tables
- Faster spectrogram review with AI pre-classification

See the [Wharton case study](/wharton) for the full story.

## Disclaimer

Estimates assume baseline traditional workflow against full BioSonic adoption. Results vary by site complexity and reviewer experience.
