Hypercompression applied during mixing or mastering cannot be undone at a later stage
Once dynamic range has been destroyed through hypercompression, it cannot be recovered. This makes aggressive compression an irreversible decision. A mastering engineer who receives an over-compressed mix has no way to restore the dynamics — ‘you can’t uncompress something once it’s already maximized.’ This irreversibility makes restraint in compression essential at every stage in the production chain.
Examples
Glenn Meadows describes receiving mixes that ‘look like a 2 by 4’ in the workstation—full level from the intro, with no dynamics to recover. The mastering engineer can only work within the damage already done.
Assessment
Why is it crucial to avoid hypercompression during mixing rather than correcting it at the mastering stage?
