At the bottom of the ImmerGo client control page, you will find the two binaural buttons.
ImmerGo Binaural – Playback
ImmerGo has a binaural playback and recording capability. This allows you to hear spatialized sound over headphones. The ImmerGo binaural implementation attempts to emulate, over headphones, the sound source spatialization that you get over an immersive configuration of loudspeakers.
To play binaural, you can select the “Binaural” button. Playback will be to whatever you have set your system settings to, for example headphones.
ImmerGo Binaural – Setting
You can adjust head width by going to “Settings”
To set the head width, you can move the slider to reflect your head width (typically around 15 cms) and then select “Set Width”. Increasing the head width will increase the delay of sound to the far ear as well as reducing gain.
To record binaural, you should type in the name of a file and click “Submit”
ImmerGo Binaural – Recording
To record , select “Binaurl” and then select “BinRec”.
ImmerGo Binaural – Head Height
You can adjust the height of the listener head at the time that you configure the speakers.
If your goal with the binaural capability is to emulate what you would typically hear with a particular speaker configuration, then of course you would adhere to this configuration. However, if your goal is to get a good binaural recording, then you could experiment with various speaker configurations.
ImmerGo Binaural – how does it work?
ImmerGo connects USB outs from a DAW to the mixer ins. Similarly it connects mic and analogue instruments. The ImmerGo server adjusts the aux bus send levels in response to a user moving sound sources from a client. Typically the aux buses are routed to analogue outs for playback by speakers. When Binaural is selected, the aux buses are also routed to USB outs. These USB outs are the ins to a Nx2 mixer matrix in the ImmerGo server. The matrix applies appropriate delays, gains and filters at the cross points, producing a spatialised stereo signal that is sent to the ImmerGo Clients. This can be listened to over headphones.
