Build each badly it's heard (7)

I believe the answer is:

audible

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

'heard' is the definition.
(similar in meaning)

'build each badly it's' is the wordplay.
I cannot quite see how this works, but
an anagram of 'build' is 'udibl' which is present in the answer.
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is located in the answer.
A single letter 'a' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
