First-order ambisonics in Adobe Premiere

As of version 11.1 (2017.1) of Adobe Premiere Pro CC, first-order ambisonics are supported natively. Please visit Support for VR Workflows on Adobe's website for more information. If you are running an earlier version of Premiere, please use the directions below.

One-time setup

Install the ambiX Ambisonic plug-in suite.

  1. Download the 1st order (name ending in _o1) plugins, and copy to:

    • OS X: ~/Library/Audio/Plug-Ins/VST
    • Windows: %PROGRAMFILES%\Steinberg\VstPlugins (or your VST plugins directory)
  2. Download the binaural decoder presets, and copy the binaural_presets directory to:

    • OS X: ~/Library/ambix
    • Windows: %APPDATA%\Roaming\ambix
  3. Download the Thrive v1.0 binaural decoder presets, and copy the thrive_v1.0 directory to:

    • OS X: ~/Library/ambix/binaural_presets
    • Windows: %APPDATA%\Roaming\ambix\binaural_presets
  1. In Premiere, go to Preferences > Audio, and set Multichannel Mono Media to Adaptive.
  2. Go to Preferences > Audio > Audio Plug-In Manager, and click Scan for Plug-Ins.

Creating a sequence

While creating a Sequence:

  1. Go to the Tracks tab.
  2. For Audio, set Master to Multichannel and Number of Channels to 4.
  3. For each audio track, set the Track Type to Adaptive.


Importing spatial audio

  1. Import a 4-channel uncompressed audio file (.wav or .mov); it must already be in ACN/SN3D format. Audio from Zoom H2n is in this format.
  2. Drag an ambisonic audio file onto a track.
  3. Open the Audio Track Mixer for your sequence (Window > Audio Track Mixer).
  4. Add ambix_rotator_z_o1 to the audio track. This will allow you to rotate all spatial audio on the audio track it applies to.



  1. To rotate a 360 video clip and rotate its spatial audio identically:
    1. Use Premiere's Offset effect on the video clip.
    2. Use this formula to calculate the rotation in degrees for the corresponding audio track:
      [horizontal center shift] / [width of video clip] * 360 - 180
      For example, if you have a clip of width 3840 and the Offset effect has a horizontal shift of 1120, the equation is:
      1120 / 3840 * 360 - 180 = -75 degrees.
    3. Use the calculated value for the corresponding ambix_rotator_z_o1's Z-axis rot setting.
  2. Note that if you've followed this guide, the audio rotation will be applied to an audio track, whereas the video rotation will be applied to a video clip.
    If you're a pro at using Premiere, you can insert the ambix_rotator_z_o1 effect on audio clips instead:
    1. Select an ambisonic audio clip in the Sequence timeline.
    2. Open Window > Effect Controls.
    3. Open Window > Effects.
    4. Drag and drop the ambix_rotator_z_o1 effect from Effects into Effect Controls.

    The effect now applies to the specific audio clip rather than an audio track

In-editor binaural previewing

  1. Add ambix_rotator_z_o1 to the Master track. This will be used to rotate the listener (you!) for previewing.

    Note: This audio effect must be disabled prior to exporting. If it is not disabled, your exported audio will be rotated.

  2. Add ambix_binaural to the Master track.

    Note: This audio effect must be disabled prior to exporting. If it is not disabled, your exported audio will not be spatial.

  3. Double click the ambix_binaural effect in the effects chain. Each of the binaural presets has a different "pair of ears" and a different virtual speaker layout. To listen to the one used by Jump Inspector and YouTube Spatial Audio, click open and select thrive_v1.0 > symmetric_cube.
  4. If there aren't any presets visible in the list, click preset folder and select the binaural_presets directory extracted previously.

    Known issue: When you reload your project, the ambix_binaural audio effect sometimes does not reload properly which can cause silent audio or frozen playback (that is, the cursor doesn't move forward). To fix this, select the thrive_v1.0 > symmetric_cube preset again.

  5. While previewing, adjust the Master track's ambix_rotator_z_o1 rot to change the listener rotation. Be sure to set it back to 0 when you're done previewing.


Note: Before exporting, be sure to disable the Master track audio effects.

Use these settings to export for Jump Inspector and YouTube:

  • Format: Quicktime (.mov)
  • Video settings:
    • YouTube uploads- up to 6144x6144, ProRes 422 (128GB max file size)
    • Jump Inspector- we recommend first exporting the master clip and encoding a lower resolution, or exporting video and audio separately. Adobe Premiere currently prevents 4 channel exports in h.264/MP4. For more information, refer to Prepare your media.
  • Audio Codec: Uncompressed
  • Channels: 4 Channel
  • Sample Size: 16-bit
  • Audio Track Layout: Single Track
  • Channel Layout: Mono


How do I use ambisonic audio from a TetraMic?

  1. Before anything else, use the software included with the TetraMic to convert your recording from A-format to a 4-channel B-format .wav. The direct signal recorded from the TetraMic is in A-format.
  2. Import the 4-channel B-format .wav.
  3. Drag the audio onto an unused audio track.
  4. On the audio track, add the ambix_converter_o1 audio effect.
  5. Open the ambix_converter_o1 settings, and use the following preset (or enter options manually):
    • Preset: .amb / AMB plugins (full periphonic) / Tetraproc > ambix
    • Input channel sequence: Furse-Malham
    • Input normalization: Furse-Malham
    • Output channel sequence: ACN
    • Output normalization: SN3D

      • Voila! Your track should now be in ambiX format, and it's ready to be treated like any other Google-friendly spatial audio.
      • To rotate, add an ambix_rotator_z_o1 audio effect after the ambix_converter_o1 in the effects signal chain. If it is added before, the spatial audio will be rotated around the wrong axis!
