I need a cheap dual op-amp, 8 pin DIL that has a low input off set say about 1mV, needed only for low audio frequency , and 12v Vcc

Add another 1 mV of input offset voltage and go with LM358N jelly bean op amp. Can't go much cheaper than that

Cheap and audio don't usually go together (well there is NE5532 but it's for a dual rail supply)..
However, you may wish to consider the ST TS922 which can function on a 12V supply, and is intended for
audio applications and costs £1.34+VAT in single qty.
Max offset is 3mV however, unless you go for the 'A' suffix in which case it is max 0.9mV at room temp
(specified at 5V). However only the non-'A' suffix version appears in DIL.
