But that's strictly for one-way work, with the whole show originated at the far end. <br></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).<br></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.<br></p><p>Alex<br></p><p>(PS if anybody would like to buy two AudioTX ISDN licences we could talk!).<br></p><blockquote type="cite"><p>On 02 October 2016 at 12:17 Callum McLean <mail@callum-mclean.co.uk> wrote:<br><br><br>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!
