I want to change channel configuration of an ALAC audio stream inside MP4-container without multiplexing the container.
So I need to change letter H of Audio Data Transport Stream with a hex editor for all audio frames.
I installed AAC Audio ED Viewer to know where I should look at in my hex editor. Because the viewer can only handle AAC streams and I thought ALAC should look similar:

But when I open my AAC reference stream inside the MP4-container I even cannot find the audio frames in the hex editor I see in the viewer:

I can find many syncwords (0xFFF) inside media data container (mdat). But they don't match those I can see in the viewer.
Can someone tell me what I'm doing wrong here?
