I suspect your file might not have a CHNA chunk? This is required for a valid BW64 file.

If you think this should work, I'd need more details about the file to investigate.

It might also be worth trying the current master version, as the published version of the EAR is now quite old: https://ear.readthedocs.io/en/latest/install.html#install-ear

I'm new to the ADM format. Can you give an example of yaml metadata for ear-utils make_test_bwf to generate a bwf file?

I'm not sure how this is related to this issue, but there's an example in the file here:

https://github.com/ebu/ebu_adm_renderer/blob/090c4fb54347eff818389d6a2992eeb8fdd3125c/ear/cmdline/generate_test_file.py#L23-L53

It might be worth documenting this properly, but it's mostly intended to be used for testing the software itself -- I wouldn't want people to treat the YAML this accepts as a stable file format.

We should add an example to the documentation of using ear-utils replace_axml to ad ADM metadata to a plain wav file. This is the best way to do it, but it's not clear from the documentation.
