Radio station calculators
The three numbers that decide what a station costs to run: how much bandwidth the stream moves, how many listening hours the audience consumes, and how much storage the library needs. No sign-up, nothing stored.
Calculator
Bandwidth calculator
How much data your stream moves per hour, day and month, from bitrate and average concurrent listeners — plus the throughput your server has to sustain at peak.
Calculator
Listening hours (TLH) calculator
What your audience consumes against a plan allowance, how much headroom is left, and the maximum concurrent audience that allowance can actually support.
Calculator
Library storage calculator
How many gigabytes a library of a given size needs at a given quality, and how many tracks fit the storage you have.

The numbers, then the thing they describe.
These calculators size a station on paper. The guided tour shows the station itself — library, clockwheels, schedule, live studio and the listener figures these numbers are about — on one that is already broadcasting.
