BIT DEPTH
How finely each sample is measured. 24-bit gives you the headroom to record quietly and stay clean; 16-bit is the delivery format for CD.

Key takeaways
- How finely each sample is measured.
- 24-bit gives you the headroom to record quietly and stay clean; 16-bit is the delivery format for CD.
- Recording at 24-bit means you can track conservatively, leaving plenty of headroom, without the noise floor ever becoming a problem.
- Track at 24-bit peaking around −12 dBFS.
- Watch out: confusing bit depth with loudness.
Quick checklist
- Can you define bit depth in one sentence without looking?
- Can you point at bit depth in a real session, mix or contract?
- Have you tried the practical move above at least once?
- Would you catch the common mistake before it costs you a take?
- Have you opened one of the primary sources below rather than a forum thread?
BIT DEPTH IN DEPTH
Bit depth sets the resolution of each sample and therefore the dynamic range: 16-bit gives about 96 dB, 24-bit about 144 dB. Recording at 24-bit means you can track conservatively, leaving plenty of headroom, without the noise floor ever becoming a problem.
How it works in practice
Track at 24-bit peaking around −12 dBFS. The extra bits make that quiet recording just as clean as a hot one.
The mistake people make
Confusing bit depth with loudness. More bits do not make a track louder — they lower the noise floor beneath it.
WHERE BIT DEPTH SITS
Bit depth belongs to production and recording in the Sampled music glossary. Studio words: what the gear does, what the engineer is asking for, what the session sheet means.
TERMS THAT DEPEND ON BIT DEPTH
- Dither
Low-level noise added when reducing bit depth so quantisation error becomes hiss instead of distortion.
