Template for authoring ADM content that is to be encoded into MPEG-H

  • 1. FHG


The ADM file "ADM.xml" can be used as a template for authoring ADM content that is to be encoded into MPEG-H. When following the given structure and constraints, the conversion into MPEG-H has been tested and should work.
This particular ADM template is for audio scenes that contain up to 15 dynamic objects (w/o any other formats).

Audio Content:
The content includes two objects, a speaker reading a poet and moving from left to right while his volume is reduced.
And a "humming bee" which is moving into the opposite direction while increasing its volume.
Position and gain are controlled through dynamic object metadata.

Files included:
1. ADM.wav: 2-channel WAV-file with <chna> and <amxl> chunks
2. ADM.xml: The ADM-file as included in the <amxl> chunck of (1), provided separately for convenience
3. MPH.mp4: The MP4-file after conversion and encding to MPEG-H 3D Audio
4. MPH.wav: The decoded MP4-file (3)
5. IRCAM.wav: The ADM-file (1) rendered with the IRCAM-Renderer (0.3.4).
   Note: As the IRCAM-Renderer did not provide file-output, this required manual capture/truncation/normalization.
