I wonder why we can get the labes [at this point](https://github.com/pyfar/pyfar/blob/89f9ea1925756498ce751022fcab621139544c58/pyfar/plot/_interaction.py#L644) and handover to the Interaction Class, so that they can be displayed in case sth is looking at individual...

I have tried a bit in pr #700, my findings were: - Sometimes it is difficult to find documentation for what you really need. Generally the documentation is not that...

sum would be easy, same for frequency and time domain, can be implemented simular to .flatten() and .reshape(). the other ones are more tricky.

thank you for reporting, if you like to fix it. you can create a pr from derived from main. In the coorinates class we hat a similar problem. This was...

yes but you can use from_abcd independ of it, cant you?

same for the rest of the [utils](https://pyfar.readthedocs.io/en/develop/modules/pyfar.utils.html) submodule. somehow related is #831

## proposed solution Proposal for extending the utils module for all pyfar Objekts. First step, include Coordinates: each class should implement ``broadcast_cshape`` and ``broadcast_cdim`` then pyfar.utils.broadcast_cshape(object) can call this method...

i have just noticed, that ``__getitem__`` and ``__setitem__`` are not there yet, this is the implentation for slicing, see eg audio classes

What do you mean, the exact function is already returning the cutoffs, do you mean the nominal? About the naming, I was thinking nominal fractional octaves frequencies is a bit...

## proposed solution this is my proposed implementation, please comment ### pyfar.constants.fractional_frequencies_nominal() we could use the IEC 61672-1 which starts at 10Hz instead of the previous one IEC 61260:1:2014 (starts...
