IP DTL ON TEST
There’s a lot of buzz around the new IP DTL system in the voiceover and audio/radio production community at the moment, and justifiably so! The prospect of replacing ageing and costly ISDN lines and codecs with a good-sounding, easy-to-use new standard over IP is very appealing. As someone who’s used MPEG Layer 2 ISDN professionally for 16 years, I was looking forward to testing IP DTL out and exploring for myself whether it cuts the mustard versus ISDN. Indications from the majority of VOs and Producers who have tried it are that it doesn’t disappoint. But we’ve been here before – this isn’t the first IP based system to throw down its gauntlet to ISDN. So will it seize the advantage against the competition and become the ‘go-to’ system?
So I’ve had my month’s free trial and tested IP DTL with a producer colleague of mine as well as running tests of my own between a couple of devices using Chrome. What I like about it so far is the relative simplicity of use. With its 128kbps connection, IP DTL doesn’t really seem to be aiming to sound better than ISDN; just do the same sort of thing only more cheaply and conveniently on a future-proof platform. That could just be its true genius.
The sound quality at 128kbps is very good. Definitely up to scratch compared to ISDN at the same bit rate. It’s assuringly faithful to the original. The difference is similar to that between a WAV file and it’s mp3 counterpart.
In:Quality recommend an upload speed of at least 800kbps for 128kbps quality, it will cope with a little less but the faster the up speed the more stable and smooth the connection.
IP DTL has what it takes to succeed ISDN for voice work. Plus the affordable annual subscription will encourage Voices to include it in their studio arsenal with little to lose. In this day and age of optimum efficiencies and cost savings, the management of radio stations will love it too!
