Recording a call that's gradually fading (8)

I believe the answer is:

tapering

I'm a little stuck... Click here to teach me more about this clue!

'gradually fading' is the definition.
The definition and answer can be both related to change as well as being present participle verbs.
Maybe there's an association between them I don't understand?

'recording a call' is the wordplay.
'recording' becomes 'tape' (tape is a kind of recording).
'a call' becomes 'ring' (I've seen this in another clue).
'tape'+'ring'='TAPERING'

'that's' acts as a link.

Can you help me to learn more?

(Other definitions for tapering that I've seen before include "thinning out" , "Becoming less" , "getting less and less" , "Becoming gradually narrower like some candles (8)" , "Narrowing to a point" .)
