OCTIV INTRODUCES OCTIVOX AUDIO TOOLKIT FOR VOIP.Octiv, Berkeley, Calif., the audio processing innovator, has introduced the OctiVox Audio Toolkit for VoIP. This powerful developer's toolkit A set of software routines and utilities used to help programmers write an application. For graphical interfaces, it provides the tools and libraries for creating menus, dialog boxes, fonts and icons. provides an integrated solution for solving the 4 major problems with Internet phones: echo cancellation The elimination of an echo in a two-way voice transmission. Echo is created in the telephone company's central office switch when two-wire lines from the customer are converted to four-wire lines for backbone trunks. , latency, audio clarity and difficult installations. Octiv is the first company to provide an integrated solution that improves echo and audio quality while maintaining a low latency Low latency allows human-unnoticeable delays between an input being processed and the corresponding output providing real time characteristics. This can be especially important for internet connections utilizing services such as online gaming and VOIP - VOIP is not as important as environment.OctiVox achieves a 90% decrease in PC latency (sound card to OS). In typical systems, OctiVox achieves a reduction in the double round trip latency from around 500 milliseconds to around 50. Given a typical one-way network latency See latency. of 50 ms., this reduces the total delay experienced by the user from 550 to 100 ms - a major improvement. OctiVox also greatly reduces echo in Internet phones by carefully measuring the round-trip delay and then suppressing the output volume during the exact time that echo would be occurring. In order not to suppress actual speech from the user at the other end, OctiVox detects the presence of far-end speech and inhibits echo suppression Turning off the receive side of a telephone conversation, effectively making the circuit one way (half-duplex). Echo suppressors were used to eliminate echo in satellite circuits before more sophisticated echo cancellation techniques could be deployed. See echo cancellation. during such speech. For improved audio quality, OctiVox uses real-time dynamic processing, which adjusts audio signal across 3 bands every 1.5 ms for better sound quality. OctiVox operates on the audio data stream with a unique algorithm that separates the audio into multiple frequency bands, measures the amplitude and other parameters in each band, and operates on the bands by increasing or decreasing the amplitude of data. This is done in several stages with parameters chosen to achieve several important enhancements in VoIP communication. In addition, OctiVox enabled Internet phones will streamline any user's installation with automatic setup and control of almost any combination of OS and sound cards with its built-in knowledge base of numerous non-compliant audio driver implementations. "With OctiVox quality improvements, desktop Internet phones can function on par with high quality phones and conference environments," explained Octiv CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. Keith McMillen. OctiVox Features Amplitude normalization In relational database management, a process that breaks down data into record groups for efficient processing. There are six stages. By the third stage (third normal form), data are identified only by the key field in their record. - equalizes the amplitude between different source configurations (microphone, user speech habits, distance to microphone, sound card properties). Noise gating - reduces the apparent noise level and improves the clarity of speech. Spectral balancing - speech signals are dynamically given a more uniform spectral shape. Consonant consonant Any speech sound characterized by an articulation in which a closure or narrowing of the vocal tract completely or partially blocks the flow of air; also, any letter or symbol representing such a sound. and vowel vowel Speech sound in which air from the lungs passes through the mouth with minimal obstruction and without audible friction, like the i in fit. The word also refers to a letter representing such a sound (a, e, i, o, u, and sometimes y). enhancement - advanced time/frequency models of the speech process. OctiVox is available immediately for license to software developers, manufacturers, and service providers. Contact Octiv (http://www.octiv.com) for more information and pricing.
