Room Correction: What It Can and Cannot Fix

Begin with placement

Move loudspeakers, subwoofers, and seats before asking software to solve the result.

What correction handles well

Broad low-frequency peaks and level matching are strong candidates when measurements are spatially representative.

What it cannot undo

Deep cancellations, excessive decay, strong early reflections, and poor loudspeaker directivity require physical changes.

Set a sensible correction range

Correcting the entire audible band can make the result overly dependent on microphone position and target assumptions.

Conclusion

Room correction is a powerful finishing tool, not permission to skip system setup.
