Webaudio audio adm(wav) ear-render

Bonjour
J'ai développé une fonction javascript pour sauvegarder les objets audio de mon application au format ADM mais lors de la définition d'objets dynamiques ear ne restitue pas le mouvement de l'objet avec ear-render -s 0+5+0 : cela crée un fichier wav(BW64) correcte mais sans déplacement de l'objet audio.

AudioID(trackIndex=1, audioTrackUID='ATU_00000001', audioTrackFormatIDRef='AT_00031001_01', audioPackFormatIDRef='AP_00031001')
AudioID(trackIndex=2, audioTrackUID='ATU_00000002', audioTrackFormatIDRef='AT_00031002_01', audioPackFormatIDRef='AP_00031002')

je ne comprends pas pourquoi ear n'assure pas le déplacement de l'objet audio.
