This was a rather easy change, since only parameter names make use of
strings in the first place.
This also improves OOM resistance: If we can't create a parameter name,
we will just set it to the empty string.
This has been overkill from the start, and it has been bugging me for a
long time. With this change, we're probably a bit slower on most
platforms but save huge amounts of space with all in-memory sample
datastructures.
Windows are used in many DSP related applications. A prominent use case
is spectral analysis, where windowing the signal before doing spectral
analysis mitigates spectral leakage.
