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.
