Vocoder Transcoding Software

VOCAL’s vocoder transcoding software provides efficient and scalable solutions for converting between multiple vocoders. Our voice transcoder seamlessly converts audio streams from one codec to another on-the-fly. Transcoding between different rates of the same vocoder is also supported. VOCAL’s optimized speech coder transcoding software solutions minimize application resources and bandwidth.
