Audio IP Link uses the Internet to link a remote broadcast to your studio or to create an STL Studio to Transmitter link - at virtually no cost and with no licensing headaches! Audio IP link is now in use at radio stations around the world!
Audio IP link transmits a robust, glitch-resiliant high-quality audio link from one computer to another via a standard broadband internet connection (ADSL / DSL / T1 etc).
We also have several customers in remote parts of the world, utilizing bandwidth from 3G mobile phones - we supply a customized version of the software that will work with many of these, please contact us for details.
Unlike ISDN or POTS codecs, Audio IP doesn't require any special hardware, will run on an inexpensive PC or in most cases a laptop and can use your existing high-speed Internet connection (or bandwidth from a 3G telephone or datacard). There are no additional charges other than your standard Internet charge - you can stay connected all week without paying another penny!
Our 'broadcast buffer' ensures that temporary glitches or connectivity issues with your Internet Connection will not affect the high-quality audio connection from the transmit end to the receiver. Even in the event of a major sustained failure, the Audio IP link automatically checks the connection and will re-establish the link when it returns. No more constant re-dialing to bring the link back up!
The Audio IP link from Broadcast Computers is easy to setup and operate and can be operated on virtually any Internet ready computer with reasonable sound card. (Recommended minimum Windows 2000 or XP Professional with 1Ghz CPU).
Each AudioIP suite contains one 'source' (transmit) and one 'remote' receive application - so there's no other software to purchase to send audio from one location to another. Each Audio IP link is customized for each customer with their own logo and software installer.
Uses:
- Inexpensive remote broadcasts - quality good enough to send stereo music and speech from the remote broadcast back to the studio.
- Studio To Transmitter (STL) links - a cost effective alternative to RF links with high-quality audio from the Studio to Transmitter and a heartbeat text telemetery link back to the studio for confidence
- Link distant facilities for transfer of audio feeds from one computer to the other - distance no object, utilise Audio IP Link across the world!
The broadcast computers Audio IP Link software does not support multicast but is a point to point link solution.
Q What speed is needed for the internet for reliability?
A The current Audio IP Link requires 132 kbps uplink and downlink for a good solid stereo signal. An 'LQ' (lower quality, but not LOW quality) shortcut, reduces that to around 66 kbps which is used by several customers that use 'datacards' for Internet Access yet still provides good quality.
Q What if any type of compression is used?
A proprietary compression is used - without it, you'd need 1441 kbps!
Q Is a static IP address needed for the receive end?
A static address is not required at either end but can be helpful.
Q What type of delay is experienced across the net?
A Latency is anywhere from 10 seconds to 45 seconds depending on internet connection, contention and quality setting.
Q Does the sound card need to be the same at the transmit and receive ends?
A Virtually any sound card that supports standard Microsoft MME wave driver can be used. That includes all on-board sound cards I've ever tested.
