What’s New in ODEON Combined 19.02

ODEON 19 introduced a major generational update, and version 19.02 refines and stabilizes these advancements with performance improvements and corrections based on real-world professional use.

New and Enhanced Functions

Improved 3D Visualization and Rendering
ODEON Combined 19.02 delivers enhanced 3D model visualization with more accurate color handling, improved surface rendering, and clearer differentiation of materials. These improvements significantly enhance model readability, quality assurance, and communication with non-technical stakeholders.

Visual Assets and Context Objects
Users can now assign visual assets to sound sources and room elements, improving orientation within complex models. This is particularly valuable for large venues, industrial plants, and client presentations where visual context matters.

Movie Auralisation (MP4 Export)
One of the most notable additions is the ability to generate auralised walkthrough videos. Users can export MP4 movies that combine camera movement with realistic, calculated room acoustics—allowing clients and decision-makers to both see and hear the acoustic performance without VR hardware.

Higher-Resolution Material Data
Support for 1/3-octave band absorption and scattering data allows more detailed frequency-dependent material behavior. This results in higher accuracy when modeling speech intelligibility, clarity, and tonal balance in critical listening environments.

Unified Calibration Workflow
The calibration interface for Sound Strength (G) and Speech Transmission Index (STI) has been redesigned into a more intuitive and unified workflow, reducing setup time and improving consistency between simulated and measured data.

Building Acoustics Calculations
ODEON Combined now includes tools for partition wall sound insulation calculations in accordance with international standards (e.g., ISO 10140), extending its usefulness beyond room acoustics into building acoustics assessments.

Advanced Measurement and Ambisonics Tools

• Open-loop measurement support

• Real-time ambisonics playback direction control

• Decay roses for ambisonic data analysis

• Improved “Compare & Average” tools for post-processing measured results

Key Professional Highlights

Hybrid Acoustic Calculation Engine

ODEON Combined uses a hybrid simulation approach, combining image-source methods for early reflections with advanced ray tracing for late-field behavior. This ensures reliable accuracy across small rooms, large auditoria, industrial halls, and outdoor environments.

Comprehensive Acoustic Parameters

The software calculates a full set of internationally recognized acoustic metrics, including:

• Reverberation Time (T20, T30, EDT)

• Speech Transmission Index (STI)

• Sound Pressure Level (SPL, dB(A))

• Clarity (C50, C80)

• Definition (D50)

• Sound Strength (G)

• Lateral Energy Fraction (LF)

• Noise maps and spatial distributions

Industrial and Environmental Noise Modeling

Unlike many room-only tools, ODEON Combined supports industrial noise sources, outdoor propagation, and environmental noise mapping, making it suitable for factory layouts, machinery noise studies, and regulatory documentation.

Auralisation and Critical Listening

ODEON Combined allows users to listen to simulated acoustics using binaural, stereo, or multichannel playback. This is invaluable for concert hall design, classroom optimization, and client approval workflows.

CAD and BIM Integration

Import models from common architectural and engineering formats, ensuring acoustic simulations align directly with design data and reducing remodeling time.

Reporting and Documentation

Generate professional graphs, impulse responses, parameter maps, and result tables suitable for technical reports, tenders, and compliance documentation.

Bug Fixes and Stability Improvements in 19.02

Version 19.02 focuses on refinement and reliability:

• Fixed unnecessary backup file creation during material archive restoration

• Improved support for modern image formats (including WebP and SVG)

• Corrected inverse input filter handling in sweep measurements

• Ensured real-time updating of material colors during editing

• General UI refinements for source, receiver, and material management

• Overall stability and performance optimizations for large projects

These fixes make ODEON Combined 19.02 a production-ready and dependable release for daily professional use.
