Ambisonic Collection

Immersive sound from the Acoustic Atlas

The natural world is ideally suited to spatial audio and surround sound recording. Its soundscapes rarely exist in true stereo, but are heard from all directions and angles. Since 2017, we have been making multichannel ambisonic recordings in environments in Montana and other Western states. We offer a limited number of these recordings for research and personal use. They were recorded in 4-channel B-format and are distributed in Furse-Malham standard (FuMa). These files are available as uncompressed downloads but cannot be republished, rebroadcast or distributed in any form without permission of the media rights holder. If you wish to use these files in other contexts, we encourage you to contact us. We often allow free use of our sound files for noncommercial, educational projects and would love to hear how you might use them.
