• Faint Audio but loud adverts

    From pinnerite@21:1/5 to All on Mon Aug 8 17:31:54 2022
    Is there any way of lowering the advert volume to the average say, of
    the programmes?

    I am using MythTV by the way although that shouldn't make any difference.

    TIA

    I thought it was a breach of broadcasting rules to increase the volume
    for the adverts. I thought Channel 4 was fined for this. I also
    thought the test was changed to a subjective one to prevent
    broadcasters increasing compression while maintaining the same
    measured volume.

    No idea whether adverts are deliberately too loud but many TVs have an
    Auto Gain Control which automatically regulates large sound level
    differences when turned on.

    Well its not worked has it?

    I also notice that hd channels are quieter than SD and radio stations are mostly louder tan TV channels on freeview.

    Those often sound worse than not having it, due to the gain riding effects
    you get, a bit like a cheap portable tape machine used to do.

    Do you perhaps have the audio selected for one of the surround sound
    options?
    I noticed this on some of the Samsung streamed channels, but I could not figure out how to make it stereo not 5.1 in those channels.
    The other thought is that the sound of the programme has the correct
    dynamic range, but the adverts are compressed making them sound louder,
    since even the quiet bits are loud. This of course is often done
    deliberately

    Does quieter usually mean better quality? Radio 3 is quieter than the
    other stations.

    +1
    The audio on adverts on many channels are often way louder than the
    audio during the programs. The advertisers also play other audio tricks
    in order to get noticed such as common doorbell or phone ring tones
    within the adverts. The is one advert that is completely silent and it
    works so well I cannot remember what it was for :)

    There is a maximum volume that the technology can reproduce. Classical
    music has a high dynamic range, meaning that the loudness varies greatly
    during the piece. If you set a level where the loudest section is not
    clipped, the average will be relatively quiet.

    So, for classical music, low average volume is necessary to correctly
    reproduce the occasional high volume part.

    The slight catch is that, with a low average volume, quantisation noise
    is greater (or thermal noise, on analogue systems).

    Typical pop music has a low dynamic range (everything louder than
    everything else) so you can get away with setting the average volume
    higher. Talking heads also have a low dynamic range. Setting the
    average volume high doesn't lead to clipping, and may marginally reduce
    noise.

    Adverts are allowed to be 3dB louder (that's twice as loud) AIUI.

    Yesterday I was idly flicking through the Freeview radio channels. As it happens the audio was connected to an oscilloscope. The difference in
    levels between channels was very noticeable.

    Not sure about that. Twice the power, yes, but an increase (or decrease)
    of 3dB is barely noticeable.

    Way, way back, Hill Street Blues (Ch4?) always had unbelievably low
    audio during the programme, requiring the TV volume control to be set to maximum. However, the adverts must have been at least 20dB louder, necessitating a leap up from the settee and a grab for the volume knob.

    There's a few newsagents' shops called Hill Street News. There's one in Bradford called Tong Street News.

    No idea whether adverts are deliberately too loud but many TVs have an
    Auto Gain Control which automatically regulates large sound level
    differences when turned on.

    You've reminded me to check this and I found it was set to "off" on my
    Panny TV. I've just set it to "on" to see if it helps. I suppose if it's
    the same thing as what the Panny PVR manual refers to as "Dynamic range compression".

    I find the sound quality is so poor on many programmes these days that I
    resort to subtitles to hear what is being said.

    +1, except that I have to put it through a HiFi instead, but even then sometimes can't distinguish it.

    I don't usually have trouble with Scottish accents, having listened to
    them all my life, but yesterday I finally got around to watching a
    televised Fern Brady gig that I downloaded some weeks ago, after finding
    some of her contributions to 'The News Quiz' quite funny, but even
    through a HiFi found difficulty in understanding some of the 'jokes' -
    I quote that word because even those I did understand didn't seem to be
    very funny, - partly her vocal range of loudness being predominantly
    quiet with occasional shouts, partly her indistinct diction, partly the
    use of modern slang. I watched about half of it, but then lost patience
    and deleted it.

    I'm finding the need for the HiFi more and more, as the sound of speech
    often seems as though the mic is buried beneath multiple layers of clothing.
