The Chrome team wrote in the announcement post:

"Throughout the project, we worked closely with the Google VR team for their VR audio expertise. Not only was their knowledge on the spatial audio a tremendous help for the project, but the collaboration also ensured identical audio spatialization across all of Google's VR applications -- both on the web and Android (e.g. Google VR SDK, YouTube Android app)...

With emerging web-based VR projects like WebVR, Omnitone's audio spatialization can play a critical role in a more immersive VR experience on the web...We look forward to seeing what people do with Omnitone now that it's open source. "
