Hi there,
It would be cool to implement the new Sophisticated mathematical approach based on the Discrete Fourier Transform (DFT) to achieve highly accurate sample rate conversions (aka "Arbitrary Sample Rate Discrete Fourier Transform Sample Rate Converter" - ARDFTSRC) which performs very very nicely in real world resampling:

C port: https://github.com/mrspoonsi/ARDFTSRC

Hope that inspires !

Thank you for the info. That's too complicated for the simples DSD up sampling task. The trivial convolution is very relevant there.

  Of course I mean for PCM to DSD in DSDprocessor...
