The developers offer a demo version that allows you to explore the interface and run basic simulations. While it has limitations on saving projects or exporting high-resolution data, it is the best way to learn the software's unique "ray tracing" and "secondary source" methods.

If you need a tool for your own custom projects without the high cost of a professional license, consider these popular free alternatives: REW (Room EQ Wizard)

Odeon is a specialized Computer-Aided Design (CAD) program used for simulating the interior acoustics of buildings. By combining geometrical acoustics (ray tracing) with wave acoustics, Odeon accurately predicts sound propagation. Key Applications

: A powerful cloud-based suite often recommended for smaller spaces like recording studios. L-Acoustics Soundvision

Listen to what a room will sound like before it is built.

It uses ray-tracing and image-source methods similar to ODEON.

Many academic institutions hold campus or departmental licenses for ODEON. Check with your university’s engineering, architecture, or physics department to see if you can access a seat for free.

An open-source, Python-based software developed by a French university. It allows for complex 3D modeling and acoustic simulations. Pachyderm Acoustical Simulation A free plugin for

: The trial does not allow you to perform calculations on your own custom room models.

. It is free for Mac and PC and excels at testing frequency responses and specific decay times.

– A free, script-based acoustics simulator. Steep learning curve, but powerful for enclosure and room responses.

: It is intended for learning or software evaluation and cannot be used for commercial projects.

I can recommend the absolute best workflow for your specific project. Share public link
