Traditionally, engineers recommend leaving -3dB to -6dB of headroom. However, in the 32-bit float digital era, the exact number is less critical than ensuring there is no 'clipping' (distorting at 0dB) and no limiting on the master output. Headroom provides the mastering engineer with the technical space to apply processing without digital artifacts.
- 1.Aim for peak levels between -3dB and -6dB on your master fader to ensure the engineer has enough 'air' to apply EQ and compression.
- 2.Ensure your master bus has no clipping (going into the red) and remove any limiters used for loudness during the mixing phase.
- 3.Check your loudest peaks throughout the entire song, not just the loudest chorus, to make sure nothing accidentally spikes to 0dB.
- ×Avoid 'normalizing' your audio on export, as this will consume all your headroom.
- ×Do not simply pull down the master fader if your individual tracks are clipping; fix the gain staging at the source.
Focus on the quality of the mix rather than hitting a specific number. If your mix sounds great at -3dB, it will sound great at -6dB. Modern mastering engineers care more about 'dynamic range' (the gap between peak and average levels) than the absolute peak value.
