DSP Technology Paper

Whether you are building a PC-PBX, and need audio conferencing and a few channels of FAX, or are building a voice services platform and using G.168 compliant echo cancellation and full duplex audio streaming, you can do it all on a single card using PIKA Technologies’ advanced DSP based technology. This technology paper, authored by Jerry Stroobach, Director of DSP Research, PIKA Technologies, delivers a detailed answer to the question, “What is DSP based architecture?”

Echo Cancellation

Echo cancellation is needed in both circuit- and packet-switched networks, i.e. the PSTN, cellular networks and IP networks. Echo occurs when the signals are reflected back to the speaker. In the case of the PSTN this occurs when there is a discontinuity, i.e. when the 2-wire local loop changes over to a 4-wire connection in the network or in the far end telephone itself .

This paper explains why and how echo occurs and how the issue can be addressed to ensure good quality voice on every call.

Low Level versus High Level APIs

Now more than ever, application developers have the option to voice-enable their applications. Programs that traditionally did not have a voice component are now able to incorporate it. With IP telephony steadily increasing in popularity, there is a growing need for application developers to expand their capabilities to design solutions that are also suitable for an IP-centric world.

Voice Application Developers Get the Best of Both APIs

More and more application developers need tools that simplify telephony coding, giving them the power to design applications faster, get to market faster, and lower overall development cost. High-level APIs could be the answer. That said, the need for low-level APIs is not going away. There continue to be developers, well versed in TDM and IP networks, who demand the granularity and design control only a low-level API can deliver. The bottom line is developers need the best of both APIs. This white paper examines advantages of low- and high-level APIs. It also provides developers with guidelines for choosing the API that will best achieve their development requirements.
