[IDEA] equalise volume output from different 'sources'

[Mattt]

Interesting question,  though I am unsure that any player can auto-adjust for different radio stream volume.

I'm not asking for that, just being able to set radio streams output at perhaps 5dB less than 'normal'

Then, consider streams such as https://ancientfm.com/  where the volume of tracks is wildly different !
What would that take to 'normalis/ze"   Maybe some 'read ahead' setting but what overhead ?
  
Once again, that's not the issue I have nor what I'm asking for.

@Tim, this seems to be a stream problem rather than something that MoOde can resolve...was there not in the past a 'normalize' setting for MoOde that did the read ahead but limited output to 44.1 ?  Don't find it in current MoOde...but maybe not looking in the right place :-)

Another consideration is the source of the local files.  Are they bought downloads, or digitised physical?  If the level was set too low during digitisation (either by you or the firm you buy them from) that would have the same result.

A combination of both, maybe 25% downloads and the rest my own/friends rips. I didn't consider this when I was doing my own rips and generally wanted them to be exact copies, low level or not.

In the Gain and Normalization section of MPD Config there are some settings for ReplayGain and Volume normalization but I've never used or tested them.

There are no such options for radio stations but possibly some sort of of ALSA plugin could perform volume normalization on the PCM stream being output (this would also cover song files). Another possibility might be to use CamnillaDSP for this?

For the OP's issue I would definitely set the Amp volume down so that the loudest radio station does not affect the equipment and then I'd prolly change moOde Volume type to Hardware or Software and use moOde to remotely control volume. Something like that.

Could it be possible to add a parameter to the radio stations - defaulting to 0 of course - which would do the attenuation by a specified number of dBs when selected to play, and restore it when leaving the stream?

That sounds like the sort of thing I was hoping may be possible
