Headroom Calculator
Calculate audio headroom — the dBFS gap between your peak signal level and the maximum allowable level — for safe recording and mixing.
Use the Headroom Calculator
Headroom Settings
The maximum allowable level. Use 0 for raw recording, -1 for streaming masters, -2 for broadcast.
The highest peak in your signal or mix bus (e.g. -6, -12, -18). Must be below the ceiling to avoid clipping.

Common Peak Targets & Headroom
Headroom calculated at your current ceiling (-1.0 dBFS).
| Peak Level | Headroom | Typical Context |
|---|
The Formula
Both values are in dBFS. A peak of -12 dBFS with a 0 dBFS ceiling gives 12 dB of headroom. Positive result = safe; negative = clipping.
Why 24-bit Changes Things
At 24-bit depth the noise floor sits around -144 dBFS — far below audibility. Recording at -18 dBFS wastes no dynamic range while providing ample headroom for peaks, making the old 16-bit discipline of "record as hot as possible" obsolete.

Summary
Audio headroom is the difference (in dBFS) between the highest peak in your signal and the digital ceiling (0 dBFS or a chosen target ceiling). This calculator lets you enter a peak level and a ceiling, instantly shows available headroom, flags clipping risk, and builds a reference table of common recording targets. Proper headroom management prevents digital clipping while leaving room for transients and mastering.
How it works
- Enter your peak signal level in dBFS (e.g. -6 dBFS for a hot mix bus).
- Set the target ceiling — typically 0 dBFS for raw recording or -1 dBFS for mastered files.
- The calculator shows headroom = ceiling minus peak level.
- A color-coded indicator tells you whether the headroom is safe, tight, or clipping.
- A reference table lists common industry-standard peak targets and their headroom at your ceiling.
- Adjust either value in real time to explore gain-staging options.
Use cases
- Check whether a recorded track has enough headroom before mixing.
- Verify your mix bus peaks leave sufficient room for mastering.
- Plan gain staging so individual channels sum without clipping.
- Compare headroom targets for streaming, broadcast, and theatrical delivery.
- Understand why -18 dBFS is recommended as a nominal recording level.
- Quickly convert a known peak to the headroom remaining before clipping.
