iOS

Best Framework or API for recording sounds (strong exhale breath-outs in particular) in xcode?

Dear community,

I am quite new to the world of iOS development.

Looking to essentially have an app which detects blowing sounds (breath-out exhales).

Never came across any iOS intelligence which would detect a specific sound (ex. detect and respond to a breath-out sound but not to a whistle sound).

However, I am convinced that this goal is achievable using decibel input (aka sound input).

Wondering if there is a Framework or API which inputs sound where I could apply certain filters and thresholds conditions?

Appreciate any guidance, feedback or reference

Thank you all...
