CS4 FLA ole-based file: get media information from content or fla file

Hi all,

I am investigating the FLA OLE-based file format created by Adobe Flash CS4. I imported a WAV file into the project and then saved it as a FLA file. After that, I used 7z to extract the FLA file. I am struggling to extract the WAV file’s information in binary mode, even though Adobe Flash CS4 can read and retrieve details such as bit rate, bit depth, and channels for the WAV file.

This file is quite old, so if anyone has any insights, please help.

Thanks!
