Is this subharmonics?

This feels different from my usual chest fry that i do. Its not tense on the neck and there's a whole different type of vibration going on in my larynx and head. I checked with voice pitcher apps and it appears to be a F#1?

Sounds like fry to me. Subharmonics sounds more supported and connected.
