I am trying to make a lsiting for an audio assets (WAV). I have uploaded the files successfully as a .zip, however when I try to submit for review, a message pops up saying “Listing promotion requires at least one asset format.” Music and audio assets are not made or produced within Unity or Unreal engine, hence the “other” option when you add new format I imagine it should should be reserved for instances where game assets are not made using the Unreal or Unity engines. Please let me know how I’m wrong, and if anyone knows how to actually upload a listing that is solely audio that’d be greatly appreciated. Thank you
What type of bug are you experiencing?

Steps to Reproduce
Create a new listing, choose format as other, upload .zip containing audio .wav files. Fill out the rest of information for listing. Once clicking ‘submit for review’, message pops up: Listing promotion requires at least one asset format.
To submit audio products to Fab, it is mandatory to include project files (asset files) compatible with Unreal Engine or Unity Engine. Additional file formats are optional and may be included for the convenience of buyers, but they are not required.
(※Uploading asset files for either Unreal Engine or Unity Engine is mandatory. Without submitting one of these, it will not be possible to complete the product submission.)
For Unreal Engine, the supported specifications for WAV files vary depending on the engine version. Some newer versions support a 44,100Hz sample rate with 24-bit depth, while older versions only support a 44,100Hz sample rate with 16-bit depth. Therefore, to ensure asset stability and compatibility with various development environments, it is recommended to use WAV files with a 44,100Hz sample rate and 16-bit depth. Please note that MP3 files are not supported.
For Unity Engine, only WAV files with a 44,100Hz sample rate and 16-bit depth are supported. Additionally, files may be evaluated for compliance with -0.3dB True Peak and appropriate loudness (LUFS) standards, and failure to meet these standards may result in a request for changes.
I have been selling audio products in UnrealEngine Marketplace and this newly opened Fab for 4 years. I am answering your questions based on my long experience.
