Every technical system, software, or professional project uses files with specific formats that contain structured information: audio, drawings, 3D models, quotations, acoustic simulations… Understanding these formats allows for more precise work, avoids incompatibilities, and facilitates interoperability between tools.
This section explains the main types of files used in the fields of acoustic engineering, technical design, and project management: from audio formats such as MP3 or WAV, to modeling files like BIM, acoustic simulation formats like EASE, technical drawings like DWG, or quotation files like BC3.
Each file not only stores data — it also defines how that data is interpreted, shared, and integrated into the project.
What is an MP3 file and what is it used for?
MP3 is a compressed audio format that reduces file size by removing information barely perceived by the human ear. Although it loses some quality compared to the original, it allows music to be stored and shared easily.
It is the most popular format for listening to music on phones, players, and digital platforms.
What is a WAV file and how does it differ from other formats?
WAV is an uncompressed audio format that preserves the full original sound quality. It is ideal for professional editing, recording, and mastering, although its files are much larger than MP3s.
If you’re looking for total audio fidelity, WAV is the reference format.
What are EASE files and what are they used for?
EASE files are used in acoustic simulation software to model how sound behaves in a space. They may include loudspeaker data, room geometry, and acoustic parameters. The most common formats are GLL, CF2, and others specific to EASE Focus, EASE Address, or EASE 5.
They allow prediction of how a sound system will perform before installation.
What is a BIM file and what does it contain?
A BIM (Building Information Modeling) file contains 3D building models along with technical information: materials, costs, timelines, energy efficiency, etc. It can have different formats depending on the software: RVT (Revit), PLN (Archicad), IFC (open format), among others.
It’s not just a drawing: it’s a digital model with real data for designing, building, and managing.
What is a DWG file and what is it used for?
DWG is a file format used in computer-aided design (CAD) programs, such as AutoCAD. It contains 2D and 3D technical drawings, along with metadata describing dimensions, layers, and annotations. It is one of the most widely used formats in architecture, engineering, and industrial design.
It is the ultimate “digital blueprint”: precise, editable, and compatible with multiple CAD tools.
What is a BC3 file and where is it used?
BC3 is a standard format in the construction sector, also known as FIEBDC. It allows information exchange between budgeting software, measurement tools, and product databases. It is used to share budgets, catalogs, certifications, and project items between manufacturers, installers, and designers.
It is the common language that connects technical software on construction sites, avoiding duplication and errors.
