Efficient Arbitrary Resampling using Frequency Domain Techniques.
Wessel Lubberhuizen
It is well known that filtering can be done very efficiently in the frequency domain. It is usually assumed that the input and output sampling frequencies need to be the same, or integer multiples of one another. In this talk I will show how frequency domain filtering can even be applied when the input and output sampling rates are completely arbitrary, i.e. not related by an integer or even a rational factor. The approach can be used for communications systems and audio applications.
