Audio Sample Rate Calculator
Calculate audio file size based on sample rate, bit depth, channels, and duration.
Plan your storage for recording sessions.
Audio File Size
Uncompressed audio file size is determined by the sample rate, bit depth, number of channels, and duration.
File Size (bytes) = Sample Rate × Bit Depth / 8 × Channels × Duration (seconds)
File Size (MB) = File Size (bytes) / 1,048,576
Common sample rates:
- 44,100 Hz (44.1 kHz) — CD quality
- 48,000 Hz (48 kHz) — Standard for video/film
- 96,000 Hz (96 kHz) — High-resolution audio
- 192,000 Hz (192 kHz) — Studio master quality
Common bit depths:
- 16-bit — CD quality (96 dB dynamic range)
- 24-bit — Professional recording (144 dB dynamic range)
- 32-bit float — Modern DAW internal processing
Channels:
- 1 — Mono
- 2 — Stereo
Reference: 1 minute of 44.1 kHz / 16-bit stereo audio = ~10.1 MB (uncompressed WAV)
