The article reports on the launch of the DIVA Server V-Series family of adapters from Eicon Networks Corp. for voice, speech and conferencing applications. The new family is a dedicated range of intelligent adapters that is designed to integrate with applications to deliver high performance, rich functionality and cost savings. The Diva Server V-Series adapters are fully scalable with versions for E1, T1 and ISDN Primary Rate along with multiple and single ISDN Basic Rate allowing a mix of four adapters to be combined in a server delivering up to 120 communication channels for continuous voice and speech processing. The family provides a full set of voice processing functions including tone detection and generation, voice activity detection and echo cancellation. The Diva Server V-Series supports Generic Tone Detection and Generation capabilities to give greater flexibility in adapting to global call signaling standards.

Deals with the release of an acoustic echo suppression software program optimized for packet telephony applications on personal digital assistants by Global IP Sound in 2003. Features of the software program; Significance to the suppression technology sector.

This article reports on the launch of the Voice Quality Enhancement (VQE) module for ATA by audio processing vendor Global IP Sound in 2005. VQE cancels echo and noise through adjusting the levels of speech, to improve voice quality in ATA box systems. Network Echo Cancellation Integrated Access Device, Noise Suppression, Comfort Noise Generation, and Voice Activity Detection are some of the VQE for ATA technologies. VQE modules does not only empower applications vendors, but also utilizes technology to put a high quality echo and noise cancellation technology for the ATA market.

This article reports on the Echo Canceller Controller patent application filed by telecommunications and routing equipment provider Sangoma Technologies Corp. in 2005. The application was made by the firm to enhance the efficiency of echo cancellation hardware and software. The firm's Echo Detection and Control examines call when connected and determines whether the call has echo or not. Then it either enables or disables the echo canceller.

This article reports that Zarlink Semiconductor Inc. has unveiled voice-processing chips aimed at improving voice quality and reducing noise in hands-free communication devices. The ZL38002 uses an advanced adaptive algorithm that constantly tracks and reduces background noise while preserving high voice quality. The chip uses an advanced nonlinear process design supporting full-duplex speech with no switched loss of the signal path. Zarlink's algorithm design operates during double-talk situations when both callers are speaking at the same time. Hands-free system microphones also pick up background noise, such as an accelerating car engine, and tire noise, which further degrade voice quality. Zarlink's acoustic echo canceller technology is specifically designed to deliver exceptional performance in high-background-noise environments.

The article evaluates the CompactPCI 6U central processing board, or cPCI-6840, from ADLINK Technology Inc. The new cPCI-6840 has been optimised for the Intel Pentium M processor with the Intel 855GME chipset and the multi-functional Intel 6300ESB I/O Controller Hub. Intel's high-performance, integrated graphics triple Gigabit Ethernet ports, and PMC optional Ultra-320 Small Computer System Interface (SCSI) are combined to provide a balance between computing and graphical performance. Furthermore, cPCI-6840 supports data/voice integration, low voltage differential SCSI, serial advanced technology attachment had disk drive, and echo canceller controller double data rate synchronous dynamic random access memory.

The article offers suggestions for improving audio quality of the microphone (mic). Topics discussed include use of echo cancellation cards and digital signal processors to remove extraneous sound; use of good microphones such as gooseneck mics, ceiling mounted mics, and desk-mounted line array mic; employment of soft surfaces to improve room acoustics; and the importance to gate each mic which opens the channel only when the level of incoming sound is loud.

The author focuses on the abrupt transitions of radio and television (TV) signals. He discusses the TV experimental signal frequency during earlier times and when commercial TV broadcasting commences before World War II. He mentions the designs made for the Adaptive Channel Equalizer (ACE) of Advanced Television Systems Committee (ATSC) receivers to help get rid off the echoes evident in the signals. It presents an illustration depicting the interference between transmitters.

The article cites a study on the development of an interference resisting antenna by researchers at the University of Texas at Austin that was published in the journal "Proceedings of the National Academy of Sciences." Topics mentioned the move of the researchers in breaking the symmetry between transmission and reception signals to control signals entering and exiting the antenna, feeding the device with a low-frequency modulation signal, and the applications of such antenna.
