Sample Rate Calculator
Audio numbers from sample rate, bit depth and channel count.
Terms
- Nyquist frequency: half the sample rate — the highest frequency that can be represented (22.05 kHz for 44.1 kHz).
- Uncompressed data rate:
sample rate × bit depth × channels ÷ 8(bytes/sec). A guide for PCM audio such as WAV or AIFF. - File size: data rate × seconds. Header bytes are not included. Compressed formats like MP3 are far smaller.
FAQ
- Which sample rate for distribution?
- 44.1 kHz is standard for music, 48 kHz for video. Hi-res releases also use 96 kHz / 24-bit and above.
- How much bigger is 32-bit float than 24-bit?
