Premaster Headroom: What to Deliver Before Mastering

Premaster Headroom Before Mastering

Headroom is the distance between the highest signal peak and digital full scale. It is not a magic number, but a clipped premaster leaves no room to recover damaged transients.

Avoid clipping

Keep the master bus below 0 dBFS and check the loudest section. A peak around −6 dBFS is common advice, but any clean level with real margin can work because digital gain can be adjusted transparently.

Do not normalize to 0 dBFS

Normalization is unnecessary before mastering. Preserve the natural level of the mix and avoid maximizing the waveform simply to make it look loud.

Remove unnecessary final limiting

If a limiter is only there for loudness, export a version without it. If it is essential to the artistic sound, provide both limited and unlimited references and explain the intention.

Keep resolution

Export WAV at the session sample rate and preferably 24-bit or 32-bit float. Do not convert to MP3 before mastering.

Check the beginning and end

Leave complete reverb tails and sensible silence. Remove accidental clicks, count-ins and unwanted noises, but do not cut musical decay.
