looking for STL codec advice

[OKCRadioGuy]

I have personal experience with Tieline units and Telos Z/IP Ones used as STLs. The Z/IP One will most certainly adapt and conseal lots of data issues where the normal Tieline stuff will not. For STL service, I'd most certainly recommend the Z/IP. I used it for several years as a backup to Cit. Media NY for a weekly show as their backup to ISDN.

Do you know what happens when you ass-ume?

This is what you have to do when a manufacturer doesn't state it anywhere in the specs sheets, manual or the website (all of which I've checked). So, I guess it's my fault...

BRIC-Link has 24 bit I/O. But I respectfully submit that someone who puts that spec over the ability to do the absolute best job over a varying Internet connection has his priorities a bit warped.

I put audio quality first (as people on this forum probably already know). In that sense, it's not the specs themselves that I was interested, the dynamic range was my point and the limitations it might bring on the usage of the device in the STL application.

As to who does the best job, now that is really a good question! And until someone dares to gather all these devices and do a proper comparison between the two with some repeatable network variability simulations, all we'll have are completely biased claims from manufacturers, or less biased but still biased, user experiences...

I can only agree with that...
In 2009 I arranged something you could call an exciter shootout (sorry, only available in dutch ). It was only about sound and definately not very scientific but it had quite an impact because nobody had done it before. Theblog is no longer active,but the number on the page with that test is still impressive (for something so out of date). Why? Probably because there is no marketingtalk and it is 'unbiased'?

If you are using an APT codec on a single network Sure Stream should be turned off and you should compare APT-X with the other algorithms in the box (despite being only 4:! you will probably find APT-X (suitably tweaked with regards to packet size and buffer size). My experience a couple of years ago was that the low delay (therefore allowing more buffering for a given total delay) and error concealment properties make APT-X surprisingly competitive wth the far more sophisticated approaches offered by Comrex and Telos.

You are saying the Worldcast Horizons are a liable alternative too?

Yes, I would give them serious consideration. Not sure exactly where they fit pricewise with the other options nowadays.

Another advantage to APT-X I did not mention before, is that the algorithmic delay is nearly zero (about 12 msec). So you can 200+ msec of buffering and still reasonable delay. You get that buffering "for free" so to speak.

I am sure APT will be at IBC, under the name Worldcast Systems

I think I will stick with the good old Marti STL-10 links. Very reliable, and no cost involved with a digital line. Just need to make sure you use them in a cool setting.

You can find a set very cheap on Ebay and have them refurbished and set here.

You can probably get one at this site too.

And how does this address the question of the original poster?

It is another option instead of using the big bad net ;D

 

[Worldcast]

In answer to the above, yes, APT will be there with the Horizon Next Generation, we've got some good real-world success with customers using our Sure Stream technology to deliver STL audio over open public Internet, so we don't have to be afraid of the big bad Net anymore....Worldcast Systems, booth 8.B50 in Hall 8, see you there!
