Another thread on digital compression

In your presently suggested case yes, but you can safely set it on full, and control the level in the analogue equipment if you wish.

AVI adm9's have remote analogue level control independently on all inputs, which is one of the reasons why they are so popular with HDD forum members, ....

However there is no longer any downside to controlling the volume digitally in iTunes. Version 8 onwards addressed this issue with 32 bit internal arithmetic, and so did Vista and W7. Only XP still has the problem and you have to mod the kernal mixer to cure it but nobody sensible still uses XP anyway these days. W7 and OS X 10.6.4 are excellent in this respect, and won't cause any sound quality problems with digital volume level control.

There are several apps available for downloading to do the job of remote control. I think the app called 'Remote' is possibly what you require. It's an area where Darren of HDD forum has a lot of expertise, - a quick email to him would get you good advice on the options available.

Joe, the old style Apple Tv is available from the Apple online clearance store for $149US at the moment. This has analogue sound and vision out, as well as digital, and also has a built-in hard drive for local storage of streamed content.

Old Apple Tv

It's a bargain, but you would have to be quick. The remaining supply might only last a few days. The new product is a cut-down cheaper version. The old one is a de-luxe job by comparison.

JC

 

Thanks, JC.

I had a look at the previous Apple TV thingy* but since my iMac is used for storage I think an AEX is the cheap device to try ... assuming I pass Rob's analogue AEX test.

Joe

* Too bad the old Apple TV doesn't have a regular video out, so I could use it with my TV.

P.S. Can't post on HDDA, as I asked Darren to retire my account.

 

It does have video and audio out on RCA sockets ............





They carry 'component video' (Red, Green, and Blue), - maybe your telly only does 'composite video' on RCA, - usually that's just one yellow RCA, with red and white ones for right and left stereo audio.

Aex it is then, ....... I predict you'll end up looking for a used low-cost dac, as you won't be able to resist trying the optical s/pdif out from the Aex.

JC

 

JC,

I didn't know the term for the input but, yes, composite video is what my TV has. Well, that and coax. The set is 20 years old, but it's sufficient for watching Mr. Spock and Buffy.

You've seen the picture before so I'll refrain from posting it again.



Ooops.

Joe

P.S. I'd like to get a new TV, but I think the audio-to-video size ratio should be maintained and if I buy a 42-inch plasma I'll be forced to get Autographs or Westminsters.

 

Seems like a plan to me

 

Dev,

Your mission, should you choose to accept, is to find me a pair of Autographs at a price I can afford.

Last Autograph auction on eBay hit something like $22k, so I think your only hope is to swindle a widow. And, of course, you'll have to do this twice, as I expect you'll nab the first pair.

Joe

 

Not sure where you get the idea that the volume control is 32 bit JC, it certainly isn't. Just because core audio uses 32bit integer arithmetic doesn't mean the volume control does.

And Apple have never made the claim to use a 32 bit dithered digital volume control.

 

I seem to remember the AirPort Express actually outputs a 20bit signal. Rather uncommon.

 

I'm afraid you're mistaken Simon.

This is Benchmarks instructions ..........

Set iTunes volume to "Full"
Volume settings below "full" may cause severe distortion, especially on version 6 and earlier.
The volume controls in iTunes versions 7.X and 8.X will not cause significant distortion. The user should not hesitate to use the volume control in iTunes v7.x and 8.X

OS X Snow Leopard with iTunes 9 or 10 contains further refinements. The digital volume on Macs is totally safe.

JC

 

Nice rug

 

JC,

Thanks, it really ties the room together.

The boss said I can swindle her when she becomes a widow .

 

Hmmmmm!

I've just read the thread refered to at the start and something AS posted makes me think he either has no idea how digital recording works or I don't.

As I understand things, the bit rate equates to dynamic range, not frequency extension.

I'd post the question there but the thread is now closed!

 

see my sig...

 

Which one?

 

this one !!!

believe over-use of compression is limiting dynamic range, ruining music for current and future generations?

everybody go there !!!!!!!

 

But that has nothing to do with my question.

 

yeah I know...

but it has everything to do with music, and the quality of music on the disc for the whole world is more important than what we as individuals do with it...

 

I agree, but fortunately for me I prefer classical music, which has escaped that particular blight.
