Inputs
Result
Headroom = 10 × log10(4) = 10 × 0.602 = 6.0 dB. To keep master at -6 dBFS, each track should peak at -6 – 6.0 = -12.0 dBFS. Current avg is -6, so reduce by 6.0 dB.
Inputs
Result
Headroom = 10 × log10(16) = 10 × 1.204 = 12.0 dB. Safe per-track peak = -6 – 12.0 = -18.0 dBFS. Tracks currently at -10, so reduce by 8.0 dB each.
Inputs
Result
Headroom = 10 × log10(32) = 10 × 1.505 = 15.1 dB. Safe per-track peak = -3 – 15.1 = -18.1 dBFS. Tracks at -12, so reduce by 6.1 dB each.
A good rule of thumb is 10*log10(N) dB of headroom, where N is the number of tracks. For 16 tracks, that’s about 12 dB. Most engineers target -6 dBFS per-track peaks with the master bus peaking around -6 to -3 dBFS.
| Track Count | Headroom (dB) | Safe Per-Track Peak | Master Peak |
|---|---|---|---|
| 4 | 6.0 | -12 dBFS | -6 dBFS |
| 8 | 9.0 | -15 dBFS | -6 dBFS |
| 16 | 12.0 | -18 dBFS | -6 dBFS |
| 32 | 15.1 | -21 dBFS | -6 dBFS |
| 64 | 18.1 | -24 dBFS | -6 dBFS |
Gain staging is setting proper signal levels at every point in the audio chain so that no stage clips and noise stays low. In a DAW, this means keeping individual track peaks around -18 to -12 dBFS so the master bus has headroom.
| Stage | Target Level | Why | Common Mistake |
|---|---|---|---|
| Recording | -18 to -12 dBFS | Headroom for processing | Peaking at 0 dBFS |
| Track output | -12 to -6 dBFS | Clean summing | Every track at 0 |
| Bus/group | -10 to -6 dBFS | Compressor sweet spot | Slamming the bus comp |
| Master bus | -6 to -3 dBFS | Mastering headroom | Limiting before master |
When multiple audio signals are summed, their amplitudes add together. Even if each track peaks at -12 dBFS, 16 tracks summed could peak much higher. The theoretical worst case is 10*log10(N) dB above a single track.
Target -6 to -3 dBFS on the master bus before sending to mastering. This gives the mastering engineer headroom to apply EQ, compression, and limiting without clipping. Never clip the master bus in your mix session.
Rather than turning down the master fader (which preserves internal clipping), lower all track faders by the same amount. If the master peaks at +3 dB, select all tracks and reduce by 6 dB. This maintains relative balance.
