Bit Depth Dynamic Range Calculator

Compute the theoretical dynamic range and SNR of any PCM bit depth using the 6.02·n + 1.76 dB rule.

Dynamic range / SQNR (dB)

Each bit buys ~6.02 dB of dynamic range: 16-bit = 98 dB, 24-bit = 146 dB (far below the noise floor of any analog stage, which is why 24-bit is overkill for playback but useful for mixing headroom). The +1.76 dB term comes from the RMS of a full-scale sine relative to quantization noise.

Rule / Formula

DR = 6.0206·n + 1.76 dB (theoretical SQNR of an n-bit PCM signal)
References: Pohlmann, K., 'Principles of Digital Audio'; AES quantization-noise theory
