<br>
Thank you for your answer.<br>
<br>
We as Swisscom Switzerland are in a difficult situation. We have around 1'000 Live / Replay TV Channels and 500 Radio Channels on our Platform.<br>
For Live TV we could manage the Loudness in the Transcoder/Encoding Settings. We were able to measure and align all Loudness differences and adjust to -23dB.<br>
Zapping from one TV Channel to another makes no audible difference anymore.<br>
<br>
The Problem is the change from Live TV to Radio on our Android Set-Top-Box.<br>
We are looking for a solution to align the Radio Loudness over the 500 Radio Channels.<br>
<br>
So you don't see any possibility to send an ExoPlayer message (like a Metadata) to the Player?<br>
<br>
We saw that the following commands are coming from the Backend IceCast Proxy to the Android STB:<o:p></o:p></span></p>

A static setting on the ExoPlayer in the client is not an option, because the Player is also used by other applications.<br>
Changing Volume in Set-top-box will affect all applications. <br>

<p class="MsoNormal">It’s not really a media streaming server’s (Icecast) job to alter the volume. Volume is set either by the media source or in player.<o:p></o:p></p>
