About BPJ files

A .bpj file is a Boxsim Simulation Project created by Visaton Boxsim, a specialized freeware tool used for simulating loudspeaker designs. This file stores crossover network layouts, driver specifications, and enclosure measurements. The main disadvantage of the .bpj format is that it is strictly proprietary. It only works within the Boxsim software ecosystem. You cannot natively open these files in standard text editors, web browsers, or general CAD applications. This creates a significant problem when you need to share your speaker designs with someone who uses MacOS or does not want to install specialized software. Users frequently need to convert these projects into PDF for sharing enclosure blueprints or CSV to extract raw frequency and impedance data. Because this is a closed, proprietary format, standard online converters fail to process it. Often only the original software can properly read or export the complex acoustic data. However, just drag and drop your file to identify the format, view it, and convert it when possible on convert.guru. We can inspect the file and show raw text or internal content. If our analysis detects a supported underlying or embedded format, viewing or partial conversion may still be possible.

Convert.Guru analyzes your BPJ file, detects the exact format, and lets you read the text inside.

Users also converted NPF, WCT and RQS files.

The BPJ Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our BPJ converter.
