APT Expands Offerings

Codec company APT is promoting its E1/T1 Multi-Channel Broadcast Solution, touted as a cost-effective, low-delay alternative for audio transport. It is based around APT’s WorldNet codec family and promises end-to-end delay of 5 ms.
It features full-duplex, bidirectional performance; analog and AES/EBU I/O; 32, 44.1 and 48 kHz; ISDN backup; and RS232 and remote control I/O.
The company is involved in a joint venture with U.S. telecom company Pulsecom to develop broadband audio products. At the recent NAB convention it unveiled the APT/Pulsecom Program Channel Access Unit, or PCAU, using apt-X compression in an encoder/decoder card to pass a 15-kHz signal over a standard 128 kbps ISDN link.
