E.g. today I'm watching uhd F1 via Sky -quite Sunday t.v. Volume set to 6 which is not often raised unless for a movie or box set.
In my recent aptv4k experience I have more often than not found myself raising t.v. Volume up top 10 maybe 15.
I'll re visit apt4k sound settings which I have altered recently.
Maybe I'll invest in DD again or wait on Atomos receiver becoming affordable.
T.v. Volume does have an equaliser though sky uhd with DD+ type sound is the best example I can use to get decent digi quality and volume level.
Yes a few reasons here. Coming from a broadcast background I'll explain how it all works. Channels opposed to film direct such as iTunes, BluRay, DVD are a very very different best.
A TV channel or radio station uses TONS of compression along with limiters. What this does is push EVERYTHING to the peak. It means the sound of the cars, presenters, music are all on the same level so that you are not adjusting the sound. Think of it as a horizontal line instead of a vertical line. Of course, if you were in a studio, it sound nothing like this.
Some audio compression is better or worse depending on the station/channel.
Even SKY's film channels are heavily heavily compressed in audio & picture.
A great example is the BBC iPlayer Radio App. Have a listen to that compared to FM Radio 2.
The iPlayer App on your iPhone is pretty music 100% accurate as to the sound that the producer will hear in the studio. The FM sound is compressed, and compressed and has a limiter on it. Have a listen to the presenter. The iPlayer app makes it sound more like You or Me or a Pirate Station when you hear the presenter. That's the 'real' sound. It's accurate. Now listen to the FM sound of the presenter - all polished, levels fine, more presenter style - it's actually nothing like what you'd hear from the studio and the actual presenter talking.
iTunes/BluRay/DVD is the 'pure' straight out of the studio file (like the one that SKY has in their studio) BEFORE it goes through all of those limiters, compressors, normalisation settings which 'raise' up ALL of the levels - we had to use that in 'Adobe Audition' when making & voicing & producing adverts, voice overs, radio documentaries on the MacBook Pro's.
That is why my friend you will hear a difference - think of TV as being 'processed food' whereas as iTunes is your freshly picked organic food without anything added to it!!! In this case, SKY is the McDonalds food of the media world. Enough said.
