How does 'virtual' spatial audio from a soundbar compare to an actual surround setup? Someone built a mind-blowing scanner that lets you 'see' sound waves to demonstrate it, with the help of a stuffed guinea pig and a custom-built 8-channel amp
- YouTuber PlasmatronX creates a testing rig to visually map how spatial audio waves travel
- It requires a lot of custom design, including building his own multi-channel amp
- You can download the 3D printing files and code to make your own testing rig
Have you ever wished you could see the sound waves in your room? It turns out all you need is a guinea pig and a CAT: Computer Acoustic Tomography.
In a fascinating and fun video that enraptured the whole TechRadar AV team and is well worth 11 minutes of your time, YouTuber PlasmatronX creates a testing rig that enables him to visualize how the sound waves move around the room.
