The problem I see is that your sine wave needs to have a precise amplitude for
the arcsine.
I don't understand your application so I don't know if t

I've done a few different systems similar to what you're describing - a
radio front-end tuner that generates baseband I & Q at audio rates
that's then further processed by a DSP to extract true audio.
Normally what I do is slave the DSP rate to the tuner audio rate. That's
usually possible sin
transmission of audio,.

I don't understand your project at all so not sure if this is helpful,
probably not,
but you can calculate the drift or instantanous frequency of a sine wave
on a per sample basis
using

Assuming you do not have the option of modifying the hardware,

A classic asynchronous resampling problem. Look at something like
SMPTE drop frame resampling using
