In this contribution a new method for artificial bandwidth extension of telephone speech towards frequencies below 300 Hz is proposed. The method defines a self-contained module which can be applied to any artificial bandwidth extension system, designed for extending the bandwidth only to frequencies above the telephone-band. At this, the amplification of a separate ARMA filter with a pass-band...
