Estimate a compressed audio file size from bitrate and duration.
Multiplying the bitrate by the length in seconds and dividing by eight yields the stored bytes of the file. Bitrate is the main knob on quality and size for lossy formats, so estimating size tells you how much library fits on a drive.
Audio File Size
File size = bitrate x duration / 8
File size = bitrate x duration / 8 Multiplying the bitrate by the length in seconds and dividing by eight yields the stored bytes of the file.
Bitrate is the main knob on quality and size for lossy formats, so estimating size tells you how much library fits on a drive.
This calculator takes 2 inputs: Bitrate, Duration. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
