Playing mediafiles in ANNEX

ANNEX is a good web-tool for viewing corpus annotations online, but I faced a problem with .eaf annotations for audio (.wav) files. I can’t play audio in ANNEX - obviously, this tool works with video files only? Do I understand it right: if I want to view an annotation and to listen to the selected part of the waveform, I have to download both *.eaf and *.wav files? It’s a pity this can’t be done online.
I will be grateful for any solution. Thank you in advance.
