    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.

    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.
