... whenever they really describe the size of a buffer that fits in memory, or
of a block file (which is never now more than a megabyte and so could be fit in
memory all at once), or a part thereof.
... A non-narrowing conversion out to long long is a necessity, but the
conversions to float and double are simply conveniences.
Conversion from floating is explicit, to avoid unintended consequences with
arithmetic operators, when later sampleCount ceases to be an alias for an
integral type.
Some conversions are not made explicit, where I expect to change the type of
the variable later to have mere size_t width.
... And in some places where a library uses signed types, assert that
the reported number is not negative.
What led me to this, is that there are many places where a size_t value for
an allocation is the product of a number of channels and some other number.
... This makes much code agnostic about how other things (functions and
arguments) are typed.
Many of these neeed to become size_t instead of sampleCount.
These changes fix a broken build in Windows.
#include <algorithm> needed for min/max to be in std.
decltype(+name) was declaring a const variable, that could not be incremented. Changed to auto.
In particular, use an options structure for AudioIO::StartStream to simplify
calls
ControlToolBar::PlayPlayRegion also takes that structure as an argument, and a
SelectedRegion instead of two times
And other changes
The problem from the beginning has been that some parts of the code expected to
receive interleaved buffers from Dither and some expected non-interleaved buffers.
I was trying to keep the changes to a minimum, but it just wasn't possible.
The result is that Dither can now accept any combination of non-interleaved and
interleaved source and destination buffers.
I still want to review every single usage of Dither (and all of the intermediaries)
because I've seen allowances here and there for the lack of Dither returning
interleaved buffers. Since it can now return interleaved buffers, some of that
extra processing can be removed.
For Resample.* and QualityPrefs.cpp, this commit has my restructuring for distinguishing constant-rate vs variable-rate resamplers more generally. I think it's complete and ready for const-rate, but I have more review and testing to do for the var-rate cases.
Variable-rate resampling is not implemented here, so Time Tracks are still broken, but this is a milestone in getting to a more general and correct structure.
Also I think this fixes AboutDialog issues Steve noticed.
