  • Abstract
    A stereo blind source separation system for the iPhone is presented. A commercially available stereo microphone is installed on an iPhone and an input sound can be recorded by it or be transferred by PC through iTunes. The sound is then separated into two sources by a stereo-specific version of auxiliary-function-based independent vector analysis (Aux-IVA2) [1] in 1/5 the computational time of the input signal length. The quantitative evaluation for speech separation and other examples for source separation in real environments are presented.
