Good evening, everyone.

 

Is there a setting to increase the volume of the voices?

 

[littlesat]

The volume button itself…. As long providers do not send a special voice channel with the audio the volgend of voices cannot be separately increased I’m afraid.

[zebulon7]

It’s a shame, I noticed that with most files, you have to increase the volume

[littlesat]

But what do you mean now with increase the voice?

[zebulon7]

In fact, I have noticed that I often have to increase the volume to hear the voices in the series.
I don’t know if it comes from OpenPLi or files, hence my questioning.

Hi,

what audio format is present in the files where you have to increase volume? I guess it is for instance AC3 with 5.1 channel. Here an AVR has options to increase level of center speaker where most of the voices are played. An STB does not have such an option. In this case it is not so easy. AC3 has to be decoded, center increased and then send as 5.1 PCM or encoded to AC3 again before sending to the speaker. I am not sure if an STB has enough power to do that.

 

If it is only stereo then you have no chance to increase only volume of voices as they are mixed with all other noises.

Ok, i understand.

Thanks for your answer.

Hi @zebulon7,

this is not due to your STB but to the file in which video and audio tracks are compressed, thus loosing quality especially for the sound (especially for mp4 files with a small size).

 

What I do to try to remedy this:

1. use audacity software to increase the sound track up to a level there is no distortion then export the sound track to a mp3 file

2. use mkvtoolnix software to replace the original sound track wiith the updated mp3 file

 

When you used to it, it takes +/- 1 min. to do that for one file.

 

rgds,

GS

Thanks a lot.

Hello, i have the same problem, in movies sometimes the sound voices are too low.

But i you change the downmix AC and AAC properties from downmix to passthrough is more better.

But after that the global sound is low and you need to increase a lot the level.

I don't understand.

Downmix is aimed to be used for people that don't have an amplifier or a TV capable to decode the multi-channel audio. So the multi-channels audio is downmixed into stereo.

If you can heard multi-channel audio there is no need to downmix it and on your AV installation / TV you have probably different mode that allows you to increase the voice volume.

 

So what you describe is normal leave you setup into passthrough if it is working for you and select the audio mode that suits you best.

[WanWizard]

The main reason why sound has "less volume" after downmixing is that it is a very simple process where channels are added together and then amplitude corrected. A very loud channel plus a silent channel results in a downmixed channel with 50% amplitude.

 

If you can avoid it, do not use downmix.

[dudule22]

Ok.

Hi,

if you use downmix and paaathrough set the box volume to 100% and control volume with TV. This way the differences are not so high.

Yes, it was at the maximum.

But, the problem came from the activated propertie "PCM multi canaux". Now it is off and it is better. The dolby is ON.

The sound properties are :

Downmix AC3 :  passthrough

Downmix AAC :  passthrough

PCM multi canaux :  OFF

3D surround : HDMI

3D Surround speakers : Large

Another thing, with these settings, comparing to the TV sound, on the mediaplayer reader the sound (mp3 exemple) is more higher.

Why?

[dudule22]

Same result also, comparing TV sound to radio sound with theses settings.

[Pr2]

Because you are listening to stereo audio (mp3 and radio) and not mutli-channel audio.

So the volume is often higher.

[dudule22]

Yes, some channels in MPEG Layer II are higher.

But it depends also of channel, Trace Urban in AC3 is high.
