Bandwidth Calculator

Calculate bandwidth for your internet radio stream from bitrate, concurrent listeners, and monthly broadcast hours. Results include TLH (total listener hours)—a metric many streaming hosts use when sizing plans or billing.

Bandwidth per Listener
Total Peak Bandwidth
Monthly TLH (total listener hours)

TLH is concurrent listeners × broadcast hours per month (peak-style estimate). Hosts may define or meter TLH differently—check your provider’s terms.

Loudness Calculator

Upload audio files for rough loudness and peak estimates. A daily limit applies.

Informal browser estimates only: not a certified BS.1770 meter and not oversampled True Peak. Numbers are ballpark. Reference presets are informal—stations and platforms set their own targets. Typical streaming loudness often falls roughly between -23 and -14 LUFS depending on outlet and genre. For delivery specs, network QC, or legal requirements, rely on your DAW, encoder, or calibrated metering.
