could someone please recommend some alternatives for those chips:

TL 074CN
TL 072CP

i'd like to have some chips that have as few noise as possible. I dont
care if i have to spend some dollars for a chip, i want them to be pin-
compatible and nearly without noise. any suggestions?

Depends if the circuit needs the minute input current of bi-fet op-amps.

There's no shortage of really quiet bipolar ones at sensible prices.

I would think it depends on the circuit whether a bipolar would work. OPA4134
is a good bifet,
but you just can't expect it to work if you don't know the circuit. Power
supply requirments
are essential. Then there's the LME49740.

I don't know why, but I was assuming audio applications. There are all kinds
of applications that need to be fit into the mix. Is this for instrumentation
and what is the circuit ?
