Description

This plugin takes a surround mix prepared for a 7.1.4 system and converts it to 3D stereo to be listened to on headphones.

The AAX version of this specific plugin requires Pro Tools 2023.6 or later.

7.1.4 adds four ceiling channels to standard 7.1.

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.

Channels

The channel ordering used is:

Channel	AAX	VST
1	Front Left	Front Left
2	Front Centre	Front Right
3	Front Right	Front Centre
4	Left Surround Side	LFE
5	Right Surround Side	Left Surround Rear
6	Left Surround Rear	Right Surround Rear
7	Right Surround Rear	Left Surround Side
8	LFE	Right Surround Side
9	Left Top Front	Left Top Front
10	Right Top Front	Right Top Front
11	Left Top Rear	Left Top Rear
12	Right Top Rear	Right Top Rear

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.

Mode	Description
Inferred	This 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.
Virtual	This 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.
