This plugin takes a surround mix prepared for a 7.1.2 system and converts it to 3D stereo to be listened to on headphones.

7.1.2 is a standard mix format for beds in Dolby Atmos. It adds two ceiling channels to standard 7.1. Please note that this plugin does not process Dolby Atmos bitstreams directly.

The 3D aspects of the stereo are synthesised using HRTF data. This models how sound from different directions is changed as it passes around the head.


The channel ordering used is:

1Front LeftFront Left
2Front CentreFront Right
3Front RightFront Centre

7Right Surround RearLeft Surround Side

Please note that the channel ordering used by Dolby's Atmos RMU may differ. Also, the AAX order above is used when plugins interact with ProTools through the AAX software interface; other parts of ProTools may use a different default order, for instance when exporting to file.

The low frequency effect channel is not used.

The plugin is available in the Binaural Surround plugin library.


Control: Mode

Two modes are supported, "Inferred" and "Virtual". Generally, "Inferred" is recommended.

InferredThis mode is optimised for use with material that has been mixed using conventional panning techniques, such as equal-power panning or VBAP. The approach produces smooth transitions when sounds pass between speaker locations.
VirtualThis mode simply places each of the main (non-LFE) audio channels in their appropriate speaker direction. This can be worth trying when the mix has not been put together by conventional panning and the channels have a complex phase relationship.
