Overview

Organize your bat call recordings in projects. Filter and sort to find the relevant data quickly. Various diagrams and charts summarize the data well-arranged. Import, export and backup features simplify the handling of a large number of recordings.

Features

Analyse your recordings from BATLOGGERS or other devices.

Manage batlogger recordings quickly and easily

Organize your bat call recordings in projects. Filter and sort to find the relevant data quickly. Various diagrams and charts summarize the data well-arranged. Import, export and backup features simplify the handling of a large number of recordings.

Analysis made easy

The software automatically detects bat calls and displays them clearly. Customizable spectrogram and waveform visualizations with zoom and measuring aids facilitate the evaluation. Computer-assisted species identification using the integrated bat species library (European and UK species).

Get the most out of your recordings

Listen to the recordings, also time-stretched or superimposed and thus in the audible range. Thanks to the BATLOGGER’s GPS you can see on a map where the recordings were made. All BATLOGGER metadata (temperature, triggers, …) is displayed.

After the analysis, your data can easily be further processed. Export the results for example into your GIS or create your own statistics with a spreadsheet tool.

Automate recurring tasks

To speed up the analysis, various actions can be applied to recordings that meet certain criteria. For example, mark (or delete) all recordings with poor quality, add notes to certain recordings or even automatically assign species. You can add/remove/edit/reorder tasks as you wish.

This paper explores how Ribeiro operationalizes this thesis through a belt-rank structure. Section II examines the pedagogical innovation of the color-coded system. Section III analyzes the cornerstone concept of the “White to Blue” survival phase. Section IV evaluates the offensive frameworks introduced at higher belts. Section V critiques the book’s limitations, and Section VI concludes with its lasting legacy.

The book’s legacy is visible in how modern BJJ academies structure their beginner curricula: positional escapes, mounting escapes, and side control survival are now standard first-month lessons, not advanced topics. Jiu-Jitsu University transformed BJJ from a collection of tricks into a developmental science. For any practitioner, from hobbyist to world champion, returning to Ribeiro’s first principle—“Position before submission, and survival before position”—serves as a foundational reminder that in Jiu-Jitsu, the greatest victory is often simply refusing to lose. This paper explores how Ribeiro operationalizes this thesis

Traditional BJJ instruction often follows a “technique-of-the-day” model, where students learn a submission from guard, a sweep from side control, and a takedown in a single class, regardless of skill level. Ribeiro rejects this as incoherent.

The proliferation of Brazilian Jiu-Jitsu instructional materials in the 21st century has created a paradox of choice for practitioners. While many texts offer exhaustive lists of techniques, few provide an integrated conceptual framework for progression. Saulo Ribeiro, a multiple-time World Champion and member of the BJJ Hall of Fame, published Jiu-Jitsu University to address this gap. The book’s central thesis is counterintuitive within a martial art often celebrated for its offensive submissions:

Despite its limitations, Jiu-Jitsu University remains the most important single-volume textbook in the history of Brazilian Jiu-Jitsu. Its enduring value lies not in exhaustive technique cataloging but in its . By forcing the practitioner to ask, “What is my belt’s primary objective?” rather than “What submission can I try?”, Ribeiro provides a map for a decade-long learning journey.
