Can this calculator estimate the size of MP3 or AAC files?

The tool uses standard PCM formulas: sample rate × bit depth × channels × duration. It does not account for audio metadata, headers, or rounding, so actual file sizes may differ by a small margin.

What happens if I enter a very long duration, like 24 hours?

The calculator will provide the total estimated size in gigabytes for that duration at your selected settings. You can also reverse the process by entering your available storage to find the maximum recording time.

Does the calculator account for different file types like BWF or RF64?

The tool estimates size based on raw PCM data. While it does not specify BWF or RF64 headers, the calculated size serves as a solid baseline for any WAV-based format.

About this tool

What Audio Size Calculator does

The Audio Size Calculator at Sound Devices estimates the storage space needed for uncompressed PCM or WAV audio files. Users enter the sample rate, bit depth, number of channels, and recording duration to get a total file size in bytes or gigabytes. The tool also works in reverse: input a storage capacity to calculate how long you can record at your chosen settings. It is designed specifically for digital audio planning, helping engineers and producers avoid running out of space during a session. The site focuses on the technical parameters that matter most for high-quality recording, without the clutter of codec presets or bitrate conversions found on general calculators. It provides a straightforward way to compare different recording configurations side by side.

Step by step

How to use the Sound Devices Audio Size Calculator

1
Select the sample rate from the dropdown menu (e.g., 44.1 kHz or 48 kHz).
2
Choose the bit depth (e.g., 16-bit or 24-bit).
3
Set the number of channels (mono or stereo).
4
Enter the desired recording duration in hours, minutes, and seconds.
5
View the estimated file size and, if storage is known, the resulting recording time.

Is it right for you

Best for

Audio engineers and producers who need to plan storage for uncompressed WAV recordings before a session begins.

Limitations

Designed only for uncompressed PCM/WAV formats; does not estimate compressed file sizes.
Requires manual input of all four parameters; no preset templates for common audio scenarios.
Output is an estimate based on standard calculations; actual file sizes may vary slightly.
