The audio meters will not work if the player is muted.

Keep a sharp eye on your broadcasts by viewing the Audio Meter right from the BoxCast Dashboard. To get started, go to the live or past broadcast, and toggle on the Audio Meter under Stream Tools. Your browser will remember this preference, and automatically keep the meters on until you turn them off.

You’ll be able to toggle between three different modes: Peak, RMS, and LUFS. Peak shows you the highest level of your audio instantaneously (along with a "hold" of the highest peak over a period of time); RMS shows you an average of your audio levels over a short period of time; and LUFS shows you the perceived loudness of your audio levels over a slightly longer period of time.

The bars indicate the instantaneous level, measured in decibels relative to full scale (dBFS); there is a peak hold value that shows the hold time over one second, with a 20 dBFS per second decay.

This level is a good one to keep an eye on to make sure your audio doesn’t get too loud- we suggest you keep your audio peaks as close to 0 dBFS as possible without clipping (i.e. yellow and some red is ok).

RMS stands for Root Mean Squared, and shows more of an average value based on the level. This is also measured in decibels relative to full scale (dBFS).

It measures the average signal of an audio track within a window of roughly 300 milliseconds, and is used to gauge an idea of the overall level.

LUFS stands for Loudness Units relative to Full Scale; this is measured in Loudness, K-weighted, relative to Full Scale (LKFS).

LUFS is a summation of the left and right channel signals over a period of 400ms that can be used to measure the perceived (human) loudness of the broadcast.
