DSP portfolio gains Asian representation
Myonghwa Net has signed to represent Adaptive Digital's entire portfolio of DSP algorithms, chips and solutions in Korea, Japan, China, Hong Kong and Taiwan
To expand the usability of its' software to include desktop/embedded application developers, Adaptive Digital has ported many of its DSP algorithms to establish a new product line targeted to run on the standard Pentium processor. The porting of Adaptive Digital's DSP software algorithms provides application developers, middleware vendors, and system developers access to the resources needed to design, develop, and deploy innovative telephony solutions at the PC level.
This implementation of Adaptive Digital's DSP algorithms will allow PCs to perform real-time professional quality audio processing.
A voice recording system is a typical application.
In many voice-recording systems, a TI DSP is used to compress speech signals in real time prior to storing the information to a hard disk.

At a later time, an operator sitting at a PC needs to play back the recorded signal.
Prior to doing so, a PC application must decode the compressed data.
An Adaptive Digital PC-based speech decoder algorithm can be integrated into such a PC applications to perform the decoding.
Potential applications may include: PC-based telephony, conference servers, VoIP, voice record/playback systems, voicemail systems, and PC-based test equipment.
The algorithms, originally developed for DSP platforms, have retained all of the high quality standards of the company's field-tested conventional line of products.
AT and T certification of Adaptive Digital's patented G.168 echo canceller extends to the PC implemented version because the PC-based algorithms are bit-exact compared to the company's DSP-based algorithms.
The tone detectors share the benefit of low processor utilisation because they employ the same proprietary algorithm that was developed for the company's DSP-based detectors.
Similarly, the company's noise reduction shares the same voice quality as the company's DSP-based one.
The application program interface (API) is provided as a C-callable function library to be easily integrated into an end application.
This translates directly to time and money savings in development and support, while helping developers to bring a quality product to market.
