I'm trying to do frequency-band specific dynamic range compression (like multi-band compression) and was thinking of whether dynamic range compression is doable in the frequency domain or whether it's done in the "typical" filtering, gain reduction and then mixing (recombining filtered and GR'ed signals) way using time-domain signals?

Also, what are the benefits/drawbacks over time-domain?
