I’ve long had a fascination with spatial audio processing. This was in part why Voxeet caught my attention when the service initially launched. It was over a year before we were able to have them appear on VUC #471 on January 10th.
From that session you may recall that Voxeet offers a binaural conference service. Participants join a conference using a PC smart phone application. They use a stereo headset allowing the client application to provide placement of the individual participants within a controlled sound stage.
In the recent v2 release their PC client has been moved to a WebRTC foundation, leveraging Opus. I’ve done a quick analysis of their updated online demo. Newly fitted with American voices where there were once French accents, it presents 16 KHz usable audio path, suggesting a 32 KHz sample rate. It certainly sounds very good.
