ClarityHow to use this tool
- Enter sample rate, bits per sample, channels, duration.
- Select Calculate to view the result.
- Check the method and assumptions below before using the result.
The method, explained
Bytes = sample rate × bit depth × channels × duration /8. Divide by 10⁶ for decimal MB.
Using sample rate = 48 kHz, bits per sample = 24 bits, channels = 2, duration = 180 s, the result is 51.84 MB. Change these example inputs to match your task; use the method above to check each step.
Understanding your result
Uncompressed tightly packed PCM payload; file headers and sample padding are excluded. Compressed audio size is bitrate-dependent.
What to keep in mind
Uncompressed tightly packed PCM payload; file headers and sample padding are excluded. Compressed audio size is bitrate-dependent. An ideal geometric or exposure estimate. Lens behavior, stabilization, sensor crop and scene conditions may change practical results.
Common questions
How do I use this uncompressed audio file size calculator?
Estimate PCM audio payload size from sample rate, bit depth, channel count and duration. Enter sample rate in kHz, bits per sample in bits, channels, duration in s. The starting example is editable; use values for the same system or project.
Which assumptions affect this result?
Uncompressed tightly packed PCM payload; file headers and sample padding are excluded. Compressed audio size is bitrate-dependent.
