Performing it, Dua Lipa got idea for recording (7)
'for recording' is the definition.
'performing it dua lipa got idea' is the wordplay.
'performing' indicates an anagram.
'it'+'dua'+'lipa'+'got'+'idea'='itdualipagotidea'
'itdualipagotidea' with letters rearranged gives 'DIGITAL AUDIO TAPE'.
If this is the answer, I'm afraid I cannot explain it.
Can you help me to learn more?
(Other definitions for digital that I've seen before include "Made up of numerals, a watch or other display" , "numerical information" , "finger" , "Of fingers or arithmetical figures" , "Using fingers" .)
