The heart of Rapture3D is a "Higher Order Ambisonics" (HOA) decoder which can make great 3D sound on a wide range of different speaker layouts.
The "Advanced" edition comes with a configuration tool where you can tell Rapture3D about the locations of the speakers in a custom speaker layout. The computer does some scary math to set everything up, and then you can start using the other Rapture3D components:
- VST plugins can be used in some Digital Audio Workstations such as Reaper.
- The Rapture3D "OpenAL" Driver allows you to use Rapture3D in some Windows OpenAL games.
- The Rapture3D Player allows you to listen to 3D sound prepared in ambisonic formats.
This advanced edition of the software is intended primarily for advanced users who need unusual or customisable speaker layouts, or access to many speakers. If you are not intending to use this feature you may wish to consider the "User" edition for gaming, or the TOA Decoding VST Plugins for pro audio, although only Rapture3D Advanced can be tailored exactly to your listening environment.
As of version 2.7, Rapture3D has experimental support for import of personalized HRTFs from AES69 files (if you are lucky enough to have such things).
The software is designed to run on OS X (10.5+, or 10.10+ for AES69 support) or Windows (XP+) running on 32bit/64bit Intel. We use some free software, data and artwork in this product. Before purchase, please check the license agreement. Prices include VAT where applicable. By beginning the download process you agree to be bound by our terms and conditions.
The advanced edition comes with a configuration tool that lets you set up custom speaker layouts and change other audio settings.
Speaker layouts are customisable and can use large numbers of speakers. There is also a wide range of presets provided, including 5.1, 7.1, 3D7.1, Auro-3D* and 22.2. The Rapture3D headphone decoders are also available, and more.
[*] Note that the Auro-3D support does not include Auro bitstream encoding.
The current selected decoder can be used as a VST2 plugin, processing FuMa-encoded ambisonic B-Format audio at up to third order. There are four versions of this plugin included in the plugin library which produce all output channels at once. These provide up to 16, 32, 64 or 128 output channels.
There is also a version which allows complex multichannel decoders to be distributed over multiple CPU cores. This splits the output into eight-channel "blocks" which can be produced on separate tracks. Some DAWs (e.g. Reaper) can then calculate the blocks on separate CPU cores.
These plugin can be hosted in various Digital Audio Workstations (DAWs). To work with these plugins, the DAW needs to handle tracks with at least 16 channels. Right now, this means that Nuendo and Cubase do not work with these plugins. But you can use Reaper instead!
Rapture3D OpenAL Driver
The Rapture3D OpenAL driver enables the full power of Rapture3D within some OpenAL Windows games. Some games include a version of it, some can be persuaded to use it easily and some more can be made to work if you're prepared to make modificiations to your system. Take a look at our compatible games page for more details.
Please note that only some existing OpenAL games are compatible with Rapture3D and most of those require technical modifications to your system before they will run properly! See our game notes for more details.
The OSX version of this edition also includes a version of the OpenAL driver. OSX does not use a system-wide OpenAL router, so this is intended for software development. That said, you may be able to make it work with some existing OpenAL games if you know what you're doing.
The Advanced edition of the Rapture3D OpenAL driver features the following:
- High quality Higher Order Ambisonic bus running at up to fifth order.
- 3D headphone surround (using six HRTFs for different head shapes).
- High quality sample rate conversion.
- 32bit floating point signal path.
- On Windows, Microsoft DirectSound or Steinberg ASIO audio output (for access to professional audio hardware).
- On OSX, CoreAudio support.
The Rapture3D Player plays FuMa-encoded ambisonic B-Format sound files at up to third order.
Please check that everything is okay here before purchasing software.
Rapture3D "User" edition is not available on OSX, although the "Advanced" edition is. Both are available on Windows.
Supported versions of Microsoft Windows are XP, Vista, Windows 7 and Windows 8. Supported versions of Apple OSX are 10.5 or later, Intel only. However, the Rapture3D Advanced HRTF import feature requires OSX 10.10 or later to work correctly.
The "TOA Decoder - Rapture3D Advanced" VST plugins run on Windows or OSX. The plugins are available in 32bit or 64bit forms on both platforms (packaged as a Universal Binary on OSX). These plugins are not included with the Rapture3D "User" edition.
The Rapture3D OpenAL driver runs on Windows or OSX. It is available in 32bit or 64bit forms on both platforms (packaged as a Universal Binary on OSX).
The Ambisonic Player and other supporting software run on Windows or OSX, 32bit or 64bit. 32bit binaries are used on Windows and 32bit/64bit Universal Binaries are used on OSX.
The "TOA 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. The reason for this limitation is that the TOA 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 convention.
Please check your PC meets the following requirements:
- Intel Pentium IV CPU or better. High quality 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.
