VOCAL VoIP
VOCAL Technologies
Elevate voice clarity with superior noise and echo reduction.
Like all of VOCAL's software products, our VoIP stack, which features Voice Quality Enhancement, is available in various formats, including ANSI C and assembly language, specifically optimized for leading DSP architectures such as those from TI, ADI, AMD, ARM, MIPS, and Intel. These libraries are crafted to be modular, enabling them to operate as a single task on multiple operating systems or independently through a dedicated microkernel. Developers have the option to license the VoIP stack either as a standalone library or as part of a broader design solution. Factors such as acoustic echo, background noise, and reverberation can significantly degrade the quality of voice signals. VOCAL's Voice Quality Enhancement (VQE) system is designed to improve any VoIP stack by adeptly addressing and reducing these challenges. By effectively removing echo and background noise, Voice Quality Enhancement substantially enhances the quality of voice communications. This enhancement is particularly vital in hands-free situations, where acoustic echoes may obstruct meaningful conversations. Ultimately, the integration of VQE not only elevates the user experience but also promotes clearer, more effective communication, paving the way for more productive interactions overall. As a result, users can expect a noticeable difference in clarity that enhances their communication experience significantly.
