Ambi Head is a professional plugin for converting ambisonic signals into 3D binaural audio. It allows manipulations of 3D scenes (rotations and control of spatial width) and contains HRTF filters specifically designed for immersive listening and accurate reproduction of B-format signals.

Custom HRTF filters can be loaded via the integrated SOFA importer, letting users choose “custom heads” for personalized binaural rendering.

An integrated Goniometer provides visual display of the binaural output (Lissajous display) giving meaningful insights into the scene spatial properties.


  • 3D binaural decoding of Ambisonic signals
  • Spatial width control
  • Scene rotation (Z axis)
  • SOFA importer for custom HRTF filters
  • Goniometer (Lissajous display of the binaural output)
  • Sampling frequency up to 192 kHz
  • Input : B-format (WXYZ)

Ambisonics is a “scene-based” paradigm to capture, transform and render 3D audio. It is ideal for 360 videos and interactive media allowing listeners to rotate their head into the scene. If you never heard about it, a good introduction is available on Wikipedia. Free ambisonic wavfiles are also available (e.g.,

In practice, first-order Ambisonics is a 3D extension of mid/side stereo with additional height and depth channels. The resulting 4-channel signal set is called B-format. Several microphones and plugins exist to record and process B-format. For example :
Brahma microphones
Soundfield microphones

Ambi Head complements these tools. It offers an efficient and accurate solution for binaural rendering of ambisonic scenes. The internal filters have been designed for  immersive 3D listening. Users can also load their own HRTFs thanks to the integrated SOFA importer. This makes Ambi Head a universal solution for binaural Ambisonics.
