Audio Processing for Television

Just curious, are any TV stations running high end audio processors (Omnia 6, Orban 8400, Aphex 2020MKIII, etc.)?

The audio on most TV stations sounds rather lame to me, even in this day and age, I suspect most are still using the old OPTIMOD-TV?

I have no idea what they're running, but WOOD-TV in Grand Rapids has excellent audio processing (and coincidentally, their picture quality isn't too shabby, either). I can pick them up at night here in the south-central part of the state, and flipping between WOOD and any of my locals reveals that WOOD's sound is by far superior to anyone else in the area, except maybe WLNS in Lansing (which wouldn't be so bad if it weren't for the fact that it's channel 6). Can't say I recognize the processor by ear, but it sounds pretty :)<P ID="signature">______________

There are a significant number of Omnia.6 and Omnia.5 units at the uplink facilities of numerous major cable networks. Sorry, but NDA's will not allow me to say which ones, but they are HUGE! :)

We also know of quite a number of terrestrial TV Stations using Omnia.

HOLES in network audio; KXAS CH 5 DFW (Dallas/Ft. Worth))

Any of those networks include NBC, and in particular downlinks to the
Dallas/Ft Worth market - KXAS in particular?

KXAS has had a problem for over a YEAR with their over-the-air broadcast
and they are OBLIVIOUS to the problem, even when it was brought to their
attention.

I have tried several different receivers, and it is ONLY network feeds where
this problem shows up ... the station does not seem interested in tracking
down the cause; MAYBE it's network related and someone at an uplink site is
on an 'Egyption waterway' (denial) ...

The sympton is brief, but noticable (if you've got a good ear for audio)
audio 'drop outs' only on network feeds; I've heard it during the 'Matt
and Katie' show in the morning and during prime-time programs in the
evening too!

Re: HOLES in network audio; KXAS CH 5 DFW (Dallas/Ft. Worth))

Watching CSI on the Spike channel last night, and before that "Silence of the Lamns" on USA Network. On both stations, any time something came in behind the dialog (like running water on CSI, and a squeaking lawn ornment on Silence of the Lambs) the audio signal would totally break up, sounding just like really bad tape dropouts. It was terrible!

I've noticed audio problems with Spike since they first debuted. Their stereo separation is way too wide, the audio is compressed extremely highly, and the clipping is terrible. I certainly hope this isn't one of the networks Frank was referring to, because if it is, there's a big issue to be dealt with there. I don't watch enough on USA to really have noticed anything, but I don't doubt what you're saying.<P ID="signature">______________

Group,

One aspect to be aware of is that each cablle company usually adds some type of proc at their head-end. We looked into that market, but the gear that head-ends use is very low cost, and we haven't dug into that area...yet!

On account of this, you might be hearing the effects of your local cable supplier.

In reguards to the cable feeds, Frank is correct. The cable equipment does effect a lot of how these channels sound. The same for the broadcast channels.

They won't do anything about it.

In my experience it's usually something like a DBX 166, and it's almost NEVER set up right.

When you are fed a processed signal, all you really need to do is set your levels appropriately at your end, and set your single-band comp/limiter so that it doesn't do anything until threshold is exceeded. Just let it ride with an occasional flicker of the -1db g/r meter. Settings should be for a medium attack, slightly slower release, with a ratio of 1:4:1 or less.

This way, you let your feed provider do the work with their expensive box, and just use your 166 (or equivalent) as a safety net in case something changes at the point of origin.

Please correct me if I am wrong about this!

A gate with a threshold way too high. Awfull. You gotta wonder if thier "engineers" set the equipiment with a Wohler rackmount or something... or worse
