01
Choose the channel count first
Mono voice can sound clean at 64 kbps. Stereo interviews and music usually need 96 to 160 kbps so the file does not trade away clarity.

How much space will your podcast actually need?
Estimate MB, GB, MiB, and GiB from the finished duration and bitrate. Use the same units as your host before you upload a weekly back catalogue.
The storage estimate
Two inputs. Four units worth checking
Duration and bitrate tell you the audio payload. The result keeps decimal and binary units side by side so a host limit does not surprise you.
Your estimate will appear here
Set the finished duration and bitrate. You will get both decimal and binary sizes so upload limits are easier to read.
Use the estimate well
A small file still needs a plan
Bitrate is one dial in the export. Units, metadata, and the size of the back catalogue decide whether the handoff stays painless.
02
Read the unit on the upload limit
A limit stated as 500 MB is decimal. A system showing 500 MiB is binary. Compare like with like before you decide an episode fits.
03
Leave room for the export
Variable bitrate, embedded artwork, chapters, and tags move the final file away from the arithmetic. Keep a buffer for the actual export.
04
Plan the back catalogue
One episode may be small. A weekly show adds up quickly. Multiply the estimate by your publishing cadence when you size storage and delivery.
File size FAQ
Questions before you export
At 128 kbps, a 60-minute file is about 57.6 MB in decimal units, or 54.9 MiB in binary units. The exact export can be a little different when the encoder uses variable bitrate or adds metadata.
