I would like to ask if the wav file you want to use as an input is an original master file, or is it decoded from already encoded file.
I think AC4 IMS available for encoding with Dolby Media Encoder might be a good choice here. It is lightweight and can carry an immersive experience.
The WAV file is an original master file, indeed, and we would use a lossy codec like mp3 or aac, in compliance with in our podcast platform.
Our concern is about the effect of low bitrate encoding in a "rendered" immersive perception.

I'm afraid that nether mp3 nor AAC can carry proper immersive experience.
Here is a thread discussing AC4 IMS https://professionalsupport.dolby.com/s/question/0D54u00007k0lOeCAI/ac4ims-a-2channel-binaural-audio-signal-without-metadata-without-any-rendering-during-playback?language=en_US
Please note that you can request for evaluation license for Dolby Media Encoder on customer.dolby.com https://customer.dolby.com/content-creation-and-delivery/dolby-media-encoder-with-dolby-ac-4-v351. This will also allows you to use Dolby Reference Player for a proper QC your encoded content.
Please note that IMS stands for Immersive Stereo.
unfortunately we can only publish plain stereo files, so it will have to be a "rendered" binaural mix for now.
However, we will follow your suggestion and test AC4-IMS encoding, we have already made the request for the referred evaluation license,
Thanks again,
