3D Audio Effects

CRI Atom Craft can be used to create and play back 3D audio effects in various ways:

  • Creation of channel-based data in addition to horizontal surround speaker output for 5.1.2 ch and 7.1.4 ch
  • Spatial audio using Ambisonics data
  • Binaural conversion of the channels output using the software binauralizer (for environment using headphones)
  • Passthrough playback for Materials that do not require binaural processing (e.g., BGM)
  • Object-Based Audio playback with platform or OS support
  • Object-Based Audio playback with the software binauralizer (for headphone environments)

Software Binauralizer

It is the module used to perform binaural processing by software.
Binaural processing can be performed in hardware (game console) based using the platform’s OS functions. However, since each platform performs this processing differently, the output between the platforms will differ.
The software binauralizer of ADX can be used to perform binauralization and get identical results on each platform.
To use the software binaural processing via ADX, select the binauralizer in CRI Atom Craft.
Two types of binauralizers can be used:

Binauralizer type Description
CRI Binauralizer Binauralizer using headphones virtual surround effects
Sound xR Software binauralizer powered by Yamaha
Head Related Transfer Functions (HRTF). You can choose from 3 types of HRTF:
PCN: The standard HRTF of Sound xR. Recommended when sound positioning is the priority.
TC4: HRTF that minimizes timbral variations in the front. However, the sound positioning from the front will be weakened. It is recommended when the goal is to minimize the changes in pitch.
TC4A: Similar to TC4. It does not reduce timbral changes as much as TC4, but is recommended for cases where a greater sense of positioning is required (up, down, left, and right in the front).
Note
When using Sound xR as the binauralizer, the settings must be applied to the project in CRI Atom Craft.
Note: Even if you are using the trial version, be sure to change the project settings.
. When "Sound xR" is used, usage statistics information will be sent regardless of the settings in About sending usage statistics .
