I recently created a room mode calculator web app with the help of AI. Check it out and let me know if you have feedback. https://dashing-cassata-66091e.netlify.app
This will be a free tool. I decided to do this because the versions I could find online didn’t have all the functionality I really wanted - namely doing things other than a standard rectangular room, putting in the position of multiple speakers/subwoofers, changing the response based on room/boundary gain and low end roll-off, and quickly showing pressure modes for the room.
This is still a beta version and I need to do some room measurements to verify but it looks to be working well so far.
EDIT: It looks like the heat map for the pressure modes in the room is not working now.
