In numerous implementations of modern telecommunications and digital audio systems there is a need for sampling rate change of the system input signal. When the relation between signal input and output sampling frequencies is a fraction of two large

The research described in this paper attempts to give an answer to a very old question about a good sounding bell. To this end, a large number of listening tests were performed in which ten bells were compared in pairs to investigate whether bells co

Decimation is a frequently used technique in audio signal processing. This paper investigates the influence of the values of stopband attenuation of decimation filters on the subjective perception of resulting audio signals. In practice, the demands

Digital filter design can be performed very efficiently using modern computer tools. The drawback of the numeric-based tools is that they usually generate a tremendous amount of numeric data, and the user might easily lose insight into the phenomenon
