About this calculation
Duration = file size in bytes × 8 ÷ bitrate in bits per second. The 95% figure provides a practical buffer below the hard limit.
How to use this calculator
What to enter
Enter or select the following as requested: File-size limit; Maximum file size; Audio bitrate (kbps). Follow the units, valid ranges, examples, and options displayed beside each field.
What the result means
The result estimates the maximum audio duration or file size allowed by the upload limit and bitrate settings entered. Check whether the tool assumes a constant bitrate and whether the platform applies a separate file-size or duration cap.
When to use it
Use this to prepare an audio file for a platform with upload restrictions. Verify the platform’s current limits and the exported file’s actual size before uploading.
