color:#1F497D">We’ve used Skype for a few things on a mobile. You’ll need either an iRig or headset splitter (about £5 from Amazon etc) to hook up the microphone and still
use headphones. It’s fine for a few links, but I wouldn’t do anything extensive as the bandwidth is quite narrow so it sounds thin compared to something via a dedicated system like IPDTL, cleanfeed.net or source-connect (https://now.source-elements.com). The
last 2 both offer free options and we’ve had good results out of them for OB’s and down-the-line interviews. The thing to remember about Skype is that it is a VOIP product for consumers, and so will drop out rather than buffer audio; whereas a product aimed
at radio will buffer or adjust sample rates to make sure something gets through intact.

<p>I was hoping someone would mention Skype. We have three kits for live interviewing as bi-lateral operation.<o:p></o:p></p>
<p>They are affectionately known as THB1,2 and 3. THB stands for 'Talking Hand-Bag'.<o:p></o:p></p>
<p>THB1 is just a simple mobile 'phone with 12volt Yuasa battery powering a car kit in a bag with sockets for mic and headphones. Quality just tolerable but it was a start and simple to use. One of our technophobe volunteers likes it.<o:p></o:p></p>
<p>THB2 is a HP Netbook with 3G dongle in a Maplin flight case and sockets for mic and headphones. It is used with Skype only for interviewing.<o:p></o:p></p>
<p>THB3 is a Windows phone clamped on a board with notepad and a 3rd party adapter to feed headphones and take a mic. It can be used on Skype or as a mobile accepting a quality reduction if internet connection not good.<o:p></o:p></p>
<p>THB2 is also pressed into service for unilateral use on full remote OB operation using Windows Media Encoder streaming directly over the internet to studio where a PC runs WinMedia Player. We have done 4 hour OB's with no glitches being observed on a CD
quality stereo link. The down side of using this 'free' software is a 7-8second delay but that's easily covered up.<o:p></o:p></p>

<p>We've done numerous on the fly OBs - generally just using a laptop with ICEcast or similar over public internet, with complete success - all it needs is a reasonable broadband connection (we have no 3G let alone 4G within 50 miles!). But that's strictly
for one-way work, with the whole show originated at the far end. <o:p></o:p></p>
<p>For really occasional two-way work not needing music from the far end we use Skype - as long as a decent microphone and reasonably powerful PC is used, the quality of Skype nowadays is remarkably good. Of course for really on the fly work you can use a smartphone
running Skype for the remote end (and there are some quite high quality proprietary solutions for smartphones).<o:p></o:p></p>
<p>For high-quality low-latency interviews and two-way shows we used to use ISDN, but once a regularly weekly two-way show finished we couldn't justify the couple of hundred pounds a quarter for the line rental just for occasional use.<o:p></o:p></p>

I was thinking about the Barix kit, but I didn't get the impression<br>
that it was going to be robust enough... <br>
<br>
Good to know that other people have used the PS-kit successfully - and<br>
cheers for the heads-up about potentially high latency in the MP3<br>
format! Was hoping not to go down the MP3 route in any case, but still<br>
good to know...<br>
<br>
Good shout about using SIP to negotiate the connection - will look into<br>
it!<br>
<br>
Has anyone used this sort of kit in a flyaway environment - i.e. not in<br>
installations? Typically, this is the sort of thing where most people<br>
might use a) an ISDN line; b) a flyaway sat connection; c) a bonded 4G<br>
link. We *were* going to go down the multiple-carrier bonded 4G route,<br>
until the cost just became prohibitive for what we want to achieve.<br>
<br>
Also, to answer Iain's question, we're only using this over the public<br>
internet - the plan is to require the venue hosting the OB to provide<br>
us with a solid, wired internet connection - protected within their own<br>
networking infrastructure, where possible, and then do everything we<br>
can to keep latency and bandwidth down whilst retaining audio quality.<br>
The only downside with the Sonifex kit is that they don't support<br>
encoding in Opus :(<br>
