The faster, more reliable alternative to Odeon

Tired of long simulation times and outdated workflows? Treble offers a next-generation acoustic simulation platform that delivers unprecedented accuracy, cloud-native speed, and seamless BIM integration.

Why Treble, in a nutshell?

Easily communicate acoustic

Treble transforms acoustic results into immersive, perceptually authentic auralizations that stakeholders can explore in real time — shared instantly through the browser. Odeon, on the other hand, relies on outdated, janky playback that feels disconnected from reality and fails to convey how a design will truly sound.

Treble

With Treble, it’s the opposite: setting up auralizations is effortless, design comparisons happen instantly, and results live in the cloud where they can be shared with a single link. Stakeholders don’t need software or installs — just a browser. Better yet, Treble supports photorealistic architectural renders and even LiDAR-scanned models, so your audience hears and sees exactly how the space will perform.

Odeon

In ODEON, auralization is clunky, ugly, and stuck on a single desktop — good luck trying to share it.

Easy to use interface

  • Treble

    Treble replaces that with a clean, intuitive design that makes advanced acoustic simulation effortless. With streamlined workflows, automatic geometry handling, and built-in collaboration, you can focus on acoustics instead of fighting the software.

  • Odeon

    Odeon’s outdated interface forces users through clunky menus and manual setup, slowing down even simple tasks.

Real physics, fewer shortcuts

Classical Geometrical Acoustics solvers model sound as if it were light rays, an approximation that quickly loses accuracy in complex environments. Treble overcomes this limitation with a hybrid simulation engine that integrates wave-based Finite Element analysis and a phased Geometrical Acoustics solver. By applying complex boundary conditions, this approach delivers simulations with real-world precision.

Less cleanup, more design

  • Treble

    With Treble, you can drop in a full multi-space BIM model and, within minutes, it’s automatically split, cleaned, and simplified into ready-to-run simulations. No hours of model hacking, no guesswork. In a benchmark across 10 real projects, a panel of acousticians found that Treble slashed geometry prep time by 60–90% compared to the old ODEON way

  • Odeon

    With Odeon, importing a BIM model means hours of manual cleanup, splitting spaces, and fixing errors before you can even start simulating. Geometry prep is slow, repetitive, and full of guesswork — leaving you stuck doing model hacking instead of real design work.

Smoother experience, no dongle required

With Treble, all you need is a username and password. That’s it. No clunky hardware key to carry around, no frantic “Where’s the dongle?” moments, and no lost time when someone forgets it at home.Built for collaboration. Adding team members is effortless: invite them, set their permissions, and everyone has instant access. Treble’s shared material database is cloud-hosted, so updates appear for the whole team automatically.

Unlock Deeper Insights, Drive Better Decisions

  • Treble

    Make better decisions for your design with Treble’s modal analysis and result comparison. Unlike Odeon, which gives you limited output views, Treble reveals how resonant modes shape performance and lets you compare design choices side by side—turning complex results into clear, actionable insights.

  • Odeon

    With Odeon, your results are limited to a handful of static output views. There’s little support for understanding modal behavior or comparing design alternatives, leaving you to piece together insights manually and hope you caught the right details.

Smarter pricing, better support thread

Getting started with ODEON means writing a €6,000 check upfront — and if you want the full version, you’re looking at closer to €20,000. With Treble, you can be up and running for just €300 per month — no upfront costs, no dongles, no barriers. Because Treble is SaaS, you automatically get continuous improvements and updates, not the once-a-year releases ODEON makes you pay extra for. You can even pause your subscription anytime. And when you need help, Treble has real-time live support from a dedicated team — not a one-person shop. Training, webinars, and calls? They’re included, not hidden behind extra fees. Simply put: Treble makes it easier and cheaper to start, easier to grow, and easier to succeed.

Faster Simulations, Smarter Workflows

  • Treble

    Treble’s highly accelerated wave-based solver is up to 100× faster than other industry solutions, making advanced wave simulation practical at scale. With the ability to run up to 300 concurrent simulations, Treble accelerates workflows even further—allowing you to explore more options, save costs, and move from concept to decision with unmatched efficiency.

  • Odeon

    A benchmark train station acoustic simulation took only 10 minutes with Treble, compared to 33 hours with Odeon. Treble achieves this speed by leveraging the cloud, distributing heavy computations across scalable resources.

Discover Treble's hundreds of innovative features

Treble gives you access to hundreds of modern features designed for today’s workflows — from hybrid solvers and real-time auralization to seamless BIM integration and collaborative cloud tools. Odeon, by contrast, has hardly changed in decades. Its limited feature set reflects an outdated approach to simulation, forcing users to work around the software instead of pushing their designs forward.
