Can someone who has used the thingy52 microphone data comment here

Notification: Speaker Status: b'00'
Notification: Microphone: b'000000fffff08088008808008090188882180a81'
Notification: Microphone: b'febc0a3488a90903315a9370098c092134bc90f2'

Notification: Microphone: b'002d059012c12a73139b010798b0c3013aabb139'
It appears to be 20 samples per notification. is this 8KHz sampling of 16bit PCM data which equates to 2.5 msec of binary2hex samples? Does anyone have a utility or code to parse this data and save it into a wav file or some other format?
