Frequently asked questions
Does the calculator apply to WAV files?
Yes, the estimate is very suitable for uncompressed PCM WAV files. Smaller container overheads are not taken into account.
Why are MB and MiB shown separately?
MB calculates with millions of bytes, MiB with 1,048,576 bytes. Many operating systems and audio programs differentiate between these sizes.
Is FLAC also predictable?
Not exactly. FLAC compresses losslessly, but the file size depends heavily on the material.
Which setting doubles the file size?
A double sample rate, double the number of channels or double the bit depth also doubles the amount of raw data.
Can I use it to schedule multitrack recordings?
Yes. You can adjust the number of channels or calculate per track and add the results.
