Rapture3D Technical Requirements

Please check that everything is okay here before purchasing software.

Operating System

Rapture3D "User" edition is not available on macOS, although the "Advanced" edition is. Both are available on Windows.

Supported versions of Microsoft Windows are Windows 7, Windows 8 and Windows 10. Supported versions of Apple macOS are 10.7 or later, Intel only. However, the Rapture3D Advanced HRTF import feature requires macOS 10.10 or later to work correctly.

The "O3A Decoder - Rapture3D Advanced" VST plugins run on Windows or macOS. The plugins are available in 32bit or 64bit forms on both platforms (packaged as a Universal Binary on macOS). These plugins are not included with the Rapture3D "User" edition.

The Rapture3D OpenAL driver runs on Windows or macOS. It is available in 32bit or 64bit forms on both platforms (packaged as a Universal Binary on macOS).

The Ambisonic Player and other supporting software run on Windows or macOS, 32bit or 64bit. 32bit binaries are used on Windows and 32bit/64bit Universal Binaries are used on macOS.

VST Host

The "O3A Decoder - Rapture3D Advanced" VST plugins are VST 2 plugins, and require a VST 2 host to operate.

These VST plugins are not included with the Rapture3D "User" edition.

These plugins do not work with all VST 2 hosts. In particular, Cubase or Nuendo currently cannot use them. We hope this will change, but in the meantime you can use other hosts such as Reaper, Pyramix or Max/MSP. The reason for this limitation is that the O3A plugins need large numbers of channels on their input or output busses (i.e. in each track). These plugins need 16 channels on their input and 16, 32, 64 or 128 channels on their output.

The plugins expect first, second or third order B-Format using the FuMa or SN3D convention.

PC Hardware

Please check your PC meets the following requirements:

  • Intel Core i5 CPU or better. High quality or high orders will need substantially better hardware.
  • 300MB of free disk space.
  • 4GB of RAM.
  • Internal network card.
  • A working DirectSound-compatible sound card with up-to-date drivers. (And, if you want to use ASIO with the "Advanced" edition, a working ASIO-compatible sound card with up-to-date drivers.)

Internet Connection Required

The "User" and "Advanced" editions of Rapture3D available from this website require an Internet Connection for license activation and verification. We don't really like this, but we can't think of a better way to discourage piracy! Please don't hack our code, it's taken a lot of effort to get it this far...

Successful license verification isn't required every time you use Rapture3D, but it is needed during installation and needs to succeed once every couple of weeks to keep the license fresh.

The license can be "revoked" to remove it from one machine so it can be moved on to another. You should also do this if you're updating your system in case the machine appears to have changed identity.


You'll need administrator permissions while installing Rapture3D on Windows. It won't install properly using a "restricted" account.
