I tried to add highshelf filter on REW EQ window and use it with REW autogenerated filters. Didn't work. I looked at https://github.com/hifiberry/hifiberry-dsp/blob/master/hifiberrydsp/dsptoolkit.py at line 82 and noticed that the parser does not even distinguish between different filter types and treats all as peaking filters. Is there a any other easy way to add highshelf/lowshelf filtering to the dsp?

  Hi,

  I wasn't even aware that REW can also create high-shelf filters. Right now the DSPtoolkit does not support this, but it shouldn't be a big deal to implement these.

  Hi Hannu,

  we're now implemented additional filter types: shelving, notch, lowpass, highpass. Try the latest version 0.16 of DSPtoolkit that was just uploaded to PyPi.

  Best regards,
  Daniel
