Samenvatting

Bandwidth extenstion methods are required in systems that playback bandlimited signals (e.g. telephone, MP3) or that are not capable of reproducing signals with a large bandwidth (small or inexpensive loudspeakers). The first part of this paper deals with reproducing low pitched signals through small loudspeakers. This work is based on psychoacoustic phenomena to invoke a deep bass impression using only higher frequency components. The second part of this paper deals with high-frequency bandwidth extension of music and speech. In this method, no additional information on the original wide band content is required. It aims at providing a more pleasant and brighter sound impression.
