Use longer look-ahead if you want the compressor to scan further into the incoming audio to determine how much compression is needed. This will result in compression starting before the attack, allowing for slower attack time settings to be used.

So this means it cannot be on a real-time compressor?

of course it can, it only looks ahead some milliseconds!

Helps ensure no overs. Very useful on a master limiter.

hmmmm so it causes a bit of latency as well?

"Overs"?

(:oops:)

You wouldn't use it live when recording because it would add latency.

Used for mixing it can be OK if your host has automatic PDC.

"Overs?"

Helps keep from going over 0db and clipping.

As mentioned already, look ahead is very useful for limiters as it can see what is coming and shape the peak instead of just cutting it off.

A freeware limiter/maximizer that uses this is the TLs Mastering Maximizer.

Compression - What does lookahead do?
