Deleting samples at the beginning or end of chop
Sometimes you want to delete certain parts of a chop. For example when you have an audiospectrum that doesn't really provide usefull data at the edges we can use a trimCHOP to delete certain numbers of samples at the outer edges. For that we set unit values to Relative Start/End and discard Exterior. From there you can set the amount of samples you want delete in Start and End.
Be aware that if you want to delete 100 from the end the value has to be -100.
