Abstract
This paper presents a computational efficient method for extension of the bandwidth of a conference phone. The virtue of the proposed method is that it allows an improvement in quality, i.e. increased bandwidth, at virtually no extra computational cost. Frequency analysis in combination with subjective tests showed that the proposed method extends the bandwidth without introducing any artifacts.
