The function I added only works for non-interleaved real/imaginary pairs
and not the interleaved setup that r8brain expects. Fix that by removing
the multiply implementation and using the original one.

The used fork of r8brain now uses the Accelerate vDSP FFT functions for
resampling, which should provide a slight speedup, or significant for
large sample ratios.

Adding a cast here silences a warning from passing a long to a function
accepting an int. It doesn't really matter here anyway, as the long in
question is hard coded to initialize to a fixed sample rate. Even when
sample rate configuration is eventually added, this will still be hard
capped to well within the range of 32-bit integers.

Metadata logic code should be using this dictionaryWithDictionary method
so that the resulting dictionary is actually immutable, like it claims
to be, rather than simply casting it. Safety coding, all that jazz. Not
really a major issue, just feels right.

Most file formats the player supports may or may not have UTF-8 safe
strings in their metadata. This should not be assumed to be UTF-8, and
when it is assumed, it results in nil NSString objects, which results in
inline initializers crashing due to uncaught exceptions.

Moved the string encoding guesser/converter to the Plugin.h header, so
it may be accessible from any plugin. I may make it a global member of
something eventually, but a static inline for such a simple function
should be fine for now.
This function facilitates converting arbitrary 8 bit encoded strings to
Unicode NSString objects. It should be used anywhere that UTF-8 is
expected, but not necessarily guaranteed, and where other 8-bit
encodings may also be supplied by a user's files.
Not using this setup for string inputs has already led to failed UTF-8
decoding resulting in nil NSStrings being passed to the inline array or
dictionary initializers, which results in crashes due to uncaught
exceptions.

When the visualization window is not open, it should not continue to run

slow on old Intel machines, too. Full screening it is enough to bodge
the entire system session until the machine is remotely rebooted.

Introduced a brand new spectrum view based on SceneKit, with a scene
created by @kddlb and then altered by me to add the peak spheres. This

This time, a two-fer. First, ensure that file start seeking still skips
over the Xing/LAME header packet properly. Then, ensure that decoding
the last desired packet of the file does not indicate having decoded
more sample data than desired, which may have caused errors when
resuming playback position on restart and then smoothly transitioning to
the next track.

This is a possible fix for another gap issue I experienced, and may be
exposed by seeking from the start of the file without decoding first.
Signed-off-by: Christopher Snowhill <kode54@gmail.com>
This error was caused by the necessary fix of the previous commit, only
it caused something completely different. Due to the fact that MP3 is
included in the list of formats supported for embedded CUE Sheets, the
open stage performs a seek to the file start after opening the file,
even if there is no sheet embedded. And the resulting seek was supposed
to be a null operation, since the file was already at the start. But, as
a result, this reset the start skip counter to zero, and because the
offset wasn't backwards, but to the same position, it didn't reset the
skip counter to the start of track delay. So, as a result, start of
track delay wasn't being removed, introducing a gap. Now, this change
bypasses the seek function altogether if seeking would do nothing from
the current playback position. Whew.
Fixes#250 and MP3 gaplessness in general, surprised I didn't notice
this sooner myself, but I guess I didn't bother to verify whether my
change would break anything. Whoops.
Signed-off-by: Christopher Snowhill <kode54@gmail.com>
A backwards comparison led to seeking forward doing a full seek up from
the file start, and seeking backwards being a non-functional operation,
so the file would just continue playing as if there were no seek.

These two changes fix playback issues with either starting in the middle

Just in case anything using the implementation ever needs to request
less sample data than would be returned by the resampler, it should be
able to return a remainder and keep extra remaining samples, if any.
However, the way Cog currently uses it, it would not be likely to run
into this scenario.
