Binaural Surround VST

The Binaural Surround VST Plugins convert channel-based mixes into binaural stereo for headphones.

The plugins included are:

  • Binaural Surround - 5.1
  • Binaural Surround - 6.1
  • Binaural Surround - 7.1
  • Binaural Surround - 7.1.2
  • Binaural Surround - Auro-3D 9.1, 10.1, 11.1 and 13.1
  • Binaural Surround - 22.2
  • Stereo Crosstalk Cancellation

These are VST2 plugins for OS X (10.7+) or Windows (Win7+) running on 32bit/64bit Intel. They can be hosted in various Digital Audio Workstations (DAWs), but they will only work if the DAW can handle a large enough number of channels for the channel-based mix. For instance, this means that the 5.1 version can be used with Cubase, but the 22.2 version currently cannot. To use the 22.2 version you might consider Reaper or Pyramix instead.

We use some free software and data in this product. Before purchase, please check the license agreement. Prices include VAT where applicable. EU VAT is normally charged at your local rate using the MOSS VAT system, but please get in touch before purchase if you need a business-to-business transaction.

What Does This Do?

These plugins take multichannel mixes (such as 5.1) and convert them to stereo designed to be played in 3D on headphones. The sound is processed with "HRTF" data to make a binaural recording, so that sounds can be heard in 3D.

Generally, the output sounds natural on speakers, although the 3D effect is lessened. It can be strengthened through use of our Stereo Crosstalk Cancellation plugin in some circumstances.

The processing uses our Amber HRTF technology. It uses our Higher Order Ambisonic (HOA) technology internally, but you don't need to think about that while using it.


There are two modes supported. In "Virtual" mode, each channel is panned into place. Alternatively, "Inferred" mode uses a patented technique to help fill in the gaps between speakers.

Either way, we use passive processing techniques, so we don't mess with the character of the sound. You won't hear any DFT processing artefacts. Instead, the image produced is spacious and natural.

Making Great Binaural Mixes

Much as we'd hate to discourage you from buying one of our products, these plugins are not generally the best way to make great-sounding binaural mixes with our tools!

These plugins are designed to work with material that is already in legacy surround formats like 5.1. However, if you are starting from scratch, better results can be achieved using our Third Order Ambisonic (O3A) plugins. Working this way, you can build up a complete 3D audio scene using our free O3A Core plugins and others O3A plugins from our pro audio range.

If you are working with Virtual Reality, a O3A mix can be used directly with the new Rapture3D game/VR engine, and respond to head-tracking. Alternatively, if you want to decode to binaural stereo in the studio, the best option is often the "O3A Decoder - Headphones" plugin from the O3A Decoding pack, although Rapture3D Advanced can be used too. It is also possible to decode to 5.1 and many other formats.

Even if you do have legacy surround material you want to use, you could still take the O3A path via the O3A Upmixers pack. This is more complicated of course, and requires a DAW that can handle the O3A channel requirements.

However, if you neither need nor want to use ambisonics, the Binaural Surround plugins might be right for you after all!

Plugin List

Binaural Surround - 5.1

I/O: 6 in, 2 out

This plugin converts 5.1 into a 2D binaural headphone mix.

Binaural Surround VST
Binaural Surround - 6.1

I/O: 7 in, 2 out

This plugin converts 6.1 into a 2D binaural headphone mix.

Binaural Surround VST
Binaural Surround - 7.1

I/O: 8 in, 2 out

This plugin converts 7.1 into a 2D binaural headphone mix.

Binaural Surround VST
Binaural Surround - 7.1.2

I/O: 10 in, 2 out

This plugin converts 7.1.2 into a 2D binaural headphone mix.

Please note that this is not a Dolby Atmos renderer.

Binaural Surround VST
Binaural Surround - Auro-3D 9.1, 10.1, 11.1 and 13.1

I/O: 10, 11, 12 or 14 in, 2 out

This plugin converts Auro-3D into a 3D binaural headphone mix.

Note the number of channels that need to be input to this plugin. The plugin does not unpack compressed Auro-3D audio.

Binaural Surround VST
Binaural Surround - 22.2

I/O: 24 in, 2 out

This plugin converts 22.2 into a 3D binaural headphone mix.

Please note the huge input channel requirement here. Your DAW may not be able to cope!

Binaural Surround VST
Stereo Crosstalk Cancellation

I/O: 2 in, 2 out

This plugin reduces stereo crosstalk at a (rather small) sweet spot to increase the perceived stereo width there. This can produce a surprisingly wide stereo image from stereo speakers.

Tech Requirements

Binaural Surround VST Plugin Technical Requirements

Please check that everything is okay here before purchasing software.

Operating System

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. The plugins are available in 32bit or 64bit forms on both platforms (packaged as a Universal Binary on macOS).

VST Host

These plugins are VST 2 plugins, and require a VST 2 host to operate.

These plugins do not work with all VST 2 hosts. They are multichannel plugins and so will not work on VST hosts that only handle stereo. Also, note that some of the plugins need large numbers of channels on each track. For instance, the "Binaural Surround - 22.2" plugin needs 24 channels of input and so currently cannot be used with Cubase or Nuendo. We hope this will change, but in the meantime you can use other hosts such as Reaper, Pyramix or Max/MSP. Check the individual plugins for the channel counts they need.

PC Hardware

Please check your PC meets the following requirements:

  • Intel Pentium D CPU or better.
  • 200MB of free disk space.
  • Internal network card.

Internet Connection Required

These plugins 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 the software, 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 on Windows. The software won't install properly using a "restricted" account.
