Op Amps - Low noise

[MikeN]

I have a choice of two op-amps for an audio application.

Which of the two, TL064 or TLC274 would generate the lowest internal
noise in a 300 - 3000 Hz audio application.

Thanks

In such a limited voice BW they will perform equally good or bad
depending on the source, what is the impedance?

FET opamps have better low input bias-current noise compared to bipolar
input amplifiers. Bipolar opamps perform better if low voltage noise
is an issue.
