Like all of VOCAL’s software libraries, our VoIP stack with Voice Quality Enhancement is available in a variety of forms, including ANSI C and assembly language optimized implementations for leading DSP architectures (including but not limited to processors from TI, ADI, AMD, ARM, MIPS, Intel and others. These libraries are modular and can be executed as a single task under a variety of operating systems or standalone with its own microkernel. The VoIP stack software is available for licensing by developers as a library or part of a complete design. Acoustic echo, background noise, and reverberation are some of the possible causes for the degradation of the voice signal. VOCAL’s Voice Quality Enhancement (VQE) system is designed to be incorporated with a VoIP stack. Voice Quality Enhancement can significantly improve the quality of conversations by removing echo and background noise. In hands-free applications, acoustics echoes can be particularly inhibiting to a conversation.
