How to get the current audio sample during realtime using sf::Music?

^{Title says it all, really}

I've been working on a FFT application, and been using sf::Sound since then. However, when playing big files (1+ minute) you can perceive some lag in it, at certain times.

How do I, then, get the same result from

mySoundBuffer.getSamples()[iterator]

into

sf::Music

?

As shown in the official tutorial. Keep in mind that this is always just an approximation to "real-time" as you can't fully know when the samples are really being played, but this should get you very close to it.
