Bank size difference

Hi,

Thank you for sharing the information.

I think what you have observed is expected. Even though you’re using a lower sample rate on mobile, FADPCM trades compression efficiency for lower CPU usage, which often results in larger bank sizes compared to Vorbis.

You are not doing anything wrong, I have found some related discussion that might help you dive deeper into optimization strategies:

Hope this helps, let me know if you have questions.
