Volume difference

Dev Community Apps & Creations

Many people will recognise this:

 

When people in the movie/serie simply talk, you turn up the volume to just be able to hear them.

Then, during action scenes, volume goes... UP... Through the roof up. Deafening up.

 

Is there a way to level out that difference a bit?

 

Thanks!

If you find one let me know. This is not a rasplex specific issue though.

Ha! Yeah, thought so. I was hoping for a cool trick like: http://www.thefreewindows.com/2499/normalize-with-dynamic-volume-the-audio-of-vlc-player/

Thank you BTW, this is a wonderfull piece of software / raspberry pi use!

Thanks,

Well I got it fixed, but it's not for everyone:

The rasplex system sends it's audio via the HDMI interface to the tv. The television then sends the audio to my HiFi system, but before it does that, it will have normalized the volume.

It's in the menu system of the TV, it's called "Auto volume".

If it's possible to do via the TV, should it not also be possible straight from the Rasplex.

I think this is a result of 5.1 audio getting converted to stereo by your TV. Check this

This is a result of downmixing multi-channel audio to stereo - either by your transcoding software or hardware...

Are you guy's sure about this?

For I have setup the raspberry to send 5.1 audio via the HDMI cable. And whether or not I turn the "Auto Volume" on or off, I still hear audio coming from all speakers.

I would download a 5.1 test video from the Web and make sure that each channel is output correctly.

I found this issue most obviously when playing certain 5.1 content via analog out (*cough*300*cough*); the centre channel was not getting converted at all, leaving what was basically the echo of the talking on the left and right. Extremely quiet normally, but in the case of 300 they only put talking on the centre channel.

This was fixed as a bug in the audio mixer of the firmware, but I wouldn't be surprised to see something like this crop up again, even in HDMI.

See if it does it with a stereo source.
