    Hello.
    Can someone please explain to me how I can equalize the volume of different clips, using Soundtrack Pro?
    I need to increase the volume during speeches, without changing the background tone.
    Thanks.

    Add a gain filter to the clips that you want to make louder. You can do it in FCP too.

    Thank you, but it is a little more complicated. I want to equalize several different clips with different level of background tones. I want the spoken words louder, while the background tone does not change, or changes very little.

    You could try using an expander effect, in principle you can set the threshold a little higher than the background noise and put more gain in for louder sounds, i.e., the speech. Alternatively, you could use an expander in noise-gate mode (or use a simple noise gate) to reduce the gain for sound below the threshold level, setting the gain for the speech manually, then mixing in some background noise on another track to even that out (because your gated track will sound rather unnatural if you don’t).

    Either way, my experience is that it’s quite fiddly to find the sweet spot that sounds “right” though. TBH, keyframing gain levels can often get a better sounding result but that’s enormously time consuming.

    Good luck.
