Hi Whereupon,
Thank you for reaching out to Microsoft Community.
Surface Audio app is only available at the Microsoft Store for Windows devices, Google Play Store for Android and App Store for IOS. There is no standalone installer. You may need to contact your IT at work and consult if you may install the Surface Audio app on the laptop.
