Hi,

First, congratulations! Vive 3DSP seem like a great product.  

This is my first post here on the forum.  I have be working in the audio industry for the last 30 years and discovered Vive 3DSP a few days ago. I would love to use it within unity to create ambisonic sound for many good reasons. I read the documentation and downloaded the SDK but I haven't found how to output an ambisonic mix from the 3DSP audio component. Binaural (stereo) mix can be done but doesn't Vive 3DSP output third order ambisonic mix too?  Thanks for your help!

Hi Immersive Sound VR,

Thank you for your interest. We are glad to hear from you.

To clarify your question, would you like to share how you use VIVE 3DSP?
What is the scenario in Unity scene that you want to output an ambisonic mix from the 3DSP audio component?

You also said that binaural (stereo) mix can be done but doesn't Vive 3DSP output third order ambisonic mix too.
Generally, when the VIVE 3DSP is installed, the binaural (stereo) mix would contain the ambisonic output.
So would you like to tell us what the binaural (stereo) mix is in your description?
May I also ask how do you set the binaural (stereo) mix, as well as the third order ambisonic mix?

If you come up with any thing, please feel free to share to us.
We would do our best to help you.


Best regards,
Prof. 3D Sound

Thank you for the quick reply ,  The stereo mix is an encoded version of the ambisonic third order mix and this is the version used for the final medium (HDM or headphones). I call this mix binaural because once it leaves Unity it is a static (headlock mix) unless you listen to it within unity with a head mounted display.

When exporting  the audio to a third party application like Pro-Tools  you actually need the ambisonic mix (first, second or third order) to be able to finish the work. Another use for the ambisonic mix is to be able to export your mix to the Facebook 360 Spatial Workstation to encode your final movie output for different platforms such as youtube, facebook and more...

If you want to create sound for VR360 videos you have to be able to have acces to the ambisonic mix, not the actual encoded stereo binaural mix.  Please let me know if I am not clear.   :)

Just to be a little clearer,  the ambisonic mix should output a 4 channel (first order ambisonic), a 9 channel (second order ambisonic) or  a 16 channel (third order ambisonic)l audio file. This would allow Sound designers to export ambisonic stems and combine them later in their favorite 

audio workstation application.

Hi Immersive Sound VR,

Thank you for your kindly reply.

The VIVE 3DSP Audio SDK does not have this feature currently.  This is under planning and may be included in VIVE 3DSP in the future.

If you have any further questions, please ask here and we would be happy to help you.

Thanks  again for the quick reply.  I understand, the Vive 3DSP SDK is a great solution for developing VR sound within Unity  and what I am asking is a bit out of the scope.  I strongly believe that Unity is great to handle many audio tasks (because of the game object concept), but unfortunately it can not replace a standalone dedicated audio workstation. With the ambisonic outputs (bake or print) feature, Sound Designer could use the best of both world (Unity and their favorite audio Workstation).

Unfortunately I won't be able to use the Vive 3DS for VR360 video sound design but I will definitely give Vive 3DSP a try if I need to do sound design on a game or Unity VR project.

Thanks again.
