Bit depth

Bit depth is how many bits describe each audio sample — 16-bit (CD) gives about 96 dB of dynamic range; 24-bit recording gives ~144 dB of headroom for production.

Bit depth sets the distance between the loudest representable peak and the quantization noise floor. Recording at 24-bit is standard practice because it forgives conservative levels; distributing at 16-bit is transparent for listening.
