Sample Rate & Bit Depth Reference
A quick reference for what each sample rate and bit depth actually means — plus a calculator for estimating uncompressed (WAV/AIFF) file size before you record or deliver.

Sample rates
8 kHz
Telephone / low-bandwidth voice
22.05 kHz
Older multimedia, low-res web audio
32 kHz
Some broadcast/consumer video
44.1 kHz
CD standard — the common default for music & VO delivery
48 kHz
Video/broadcast standard — matches video frame-rate math cleanly
88.2 kHz
High-res, 2× 44.1 kHz (mastering)
96 kHz
High-res, 2× 48 kHz — common for film/game audio production
192 kHz
Ultra high-res capture, rarely needed for delivery
Bit depths
16-bit
CD-quality, standard delivery depth — plenty of dynamic range for finished audio
24-bit
Studio/recording standard — extra headroom for tracking & mixing
32-bit
Float — internal DAW processing headroom, rarely needed for final delivery
