Roku audio -- all over the place

ould be done but the problem with these Roku devices, chromecast etc, (even a pc) is that the audio volume levels are &^$*ing ridiculous. Netflix has a lot of dynamic range, typical of movies but it's a very real struggle to hear low passages and then of course, watch out for the loud ones. Hulu, yo utube -- all of them suck.

pressor/limiter could be built that passes through the video and could norm alize the audio ? Or wouldn't have to be inline, maybe a standalone box ?

are compression/limiting and than back to digital ?

row it out.

works great -- breakaway I think it's called. It can sound like an old scho ol broadcast compressor if you want it to.

I think it's called a "digital A/V receiver" ;-) Just enable "midnight mode" or whatever they call it now. I don't think a home-brew here can beat mass-market consumer electronics.

Dump the Roku box and get a Sony.

BTW, to use the Roku box did you have to agree to terms and conditions or an EULA sort of thing. Sony requires you to indemnify them. Then you have to dig to find the GPL.

every HDMI input av rcvr I've had (denon and yamaha) have never had any com pression. midnight mode ? what is that ?

anyway -- rather than a receiver be nice to have a device you can use inlin e to a tv etc

I don't find a need to use compression, but then most of what I watch was made for the small screen, not the big screen. I think movies use a lot more dynamic range. I thought you were saying the Roku box had a problem.

Audio is the problem -- not video. Screen size is irrelevant. I'm going to extract the audio and make it analog in my own diy box and compress the hec k out of it.

I think you did not understand a word I wrote.

I bought this originally to control TV commercials which boomed...

but it annoying "breathed" on movies, etc, where there were pauses in speech.

Tried in with my Roku Soundbridge, where it was either music or newscasts, and it was quite satisfactory.

I don't have a Roku video device so I don't know how well it would work there. ...Jim Thompson

Radio stations, particularly AM, use "companders" to keep the modulation index essentially constant. ...Jim Thompson

A compander (compressor-expander) is a misnomer here, a true one has a compressor before the transmission channel and an expander after the channel, but there is none in the receiver.

There is always a problem with automatic gain control: when to turn the gain back up and how quickly. With sufficiently long times there is no gain pumping, but quiet parts can be lost.

Another problem is an unnecessarily long quiet time after a crack or boom in the input.

I assume Rick meant that content made for the big screen have a big dynamic range to sound impressive in a movie theater

and content made for TV generally have a lower dynamic range to work in a living room

You'd think that digital audio could utilize some kind of dynamic range control so that switching channel-to-channel wouldn't have such volume differences. My cable-TV box output is horrible that way. ...Jim Thompson

That one was solved a long time ago for hearing aids by having dual time constants. There are other benefits such as improved speech perception too.

And Collins Radio had a patent on dual-time-constant AGC well before there was any AGC in hearing aids.

The encoding for 5.1 Dolby has volume control in the metadata. Some decoders let you scale that value to increase or decrease dynamic range. Sometimes it's called "night mode."

Of course, there are still plenty of older programs where the dialog point metadata is incorrect.

My sat recorder offers different presets for each channel. TV does too, but can't receive terestrial TV here.

Gotcha -- my apologies Rick. Yes, the real problem is with movies and it's very, very bad on simplistic TV audio. So bad I can't use it without 100% v olume.

Last time I did anything with a TV I put little filament lamps in series wi th the speakers. It really helped.

I think a lot of TVs these days have a built in dynamic range compressor feature, often buried somewhere in the settings.
