Find the bitrate that fits a given file size and duration.
Working backwards from a size cap, the bitrate is the total bits divided by the duration in seconds. Fitting a podcast or album into a fixed upload or download budget requires exactly this reverse bitrate calculation.
Bitrate from Data
Bitrate = bytes x 8 / duration (converted to kilobits)
Bitrate = bytes x 8 / duration (converted to kilobits) Working backwards from a size cap, the bitrate is the total bits divided by the duration in seconds.
Fitting a podcast or album into a fixed upload or download budget requires exactly this reverse bitrate calculation.
This calculator takes 2 inputs: Target file size, 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.
