Below explains some of the different settings that are available for the audio files generated for your weather forecasts.
In order to make sure all audio files are at a consistent volume, we run them through a volume normalization process. For the normalization process, we are using the EBU R128 standard which measures using LUFS (loudness units relative to full scale).
We are following the industry standard with a default value of -16 LUFS. It can be changed to be value between -11 and -21. The greater the number or the closer the number is to zero, the louder the volume will be. So -11 will be louder than -16.
