d596cf9cf3 Use a different autowah filter range 
Still just guesses, but this seems to avoid math problems with low peak gains.

d6eff654be Redo the autowah effect 
It's now a low-pass filter with a cutoff that varies according to the input
signal amplitude.

There remains issues with apparent feedback in the resonant frequency with high
resonance values. The actual cutoff range for the filter is also a guess.

034935b2e1 Modify how VCALL is handled 
Now instead of specifying the arguments as a third argument to the macro, like
VCALL(object,function,(arg1, arg2));
they are specified separately after the macro, like
VCALL(object,function)(arg1, arg2);

Also, VCALL_NOARGS has been removed in favor of VCALL0, which behaves like
above but expects an empty argument list (a separate macro is needed to work
around preprocessor limitations).

af8be56f17 Use an ALCbackend object to access playback backends 
This is the start of a backend redesign. Currently, a wrapper object is used to
avoid having to redo all the backends at once, but they should slowly be
converted to derive from ALCbackend instead. The ALCbackend interface can
change as needed.

94884ed04b Use a separate value for the maximum buffer channels 
Unlike the device, input buffers are accessed based on channel numbers
instead of enums. This means the maximum number of channels they hold
depends on the number of channels any one format can have, rather than
the total number of recognized channels. Currently, this is 8 for 7.1.

52096234e1 Limit the source step to 10 
This means the combination of the buffer frequency, source pitch, and
doppler shift can't exceed 10x the device playback frequency.

This is needed to keep the mixer from starving with a really high
increment, causing small DstBufferSize values that require a lot of
iterations.

/etc/openal/alsoft.conf, and a config found in XDG_CONFIG_HOME takes precedence
over $HOME/.alsoftrc.

cdbb0722f6 Avoid using a temp buffer for al_print 
It's now using two *printf calls, which unfortuantely means there could be a

to print to the same file. This shouldn't really be a big deal since al_print
isn't used that often, and it now allows for lines of practically unlimited
length.

32-bit floats can only reach between -16777215...+16777215 (25 bits) before it
starts losing whole-number accuracy. Some compiler optimizations may break
trying to multiply a float by 2147483647.0 when the result is given right to a
float parameter, causing it instead to multiply by the nearest representable
float value, 2147483648.0.

This won't be as granular as it could be, since it only updates when the wakeup

A more correct method would be to query GetCurrentPadding directly, but that
would require sending a message to the processing thread and waiting for a
reply, since we can't guarantee COM on the calling thread.

This update allows for much more flexibility in the HRTF data. It also allows
for HRTF table file names to include "%r" to represent the device's playback
rate (e.g. if you set hrtf-%r.mhr, then it will try to use hrtf-44100.mhr or
hrtf-48000.mhr depending if the device's output rate is 44100 or 48000,
respectively).

The makehrtf utility has also been updated to support more options and input
file formats, as well as the new mhr format.

preventing other backend devices from working.

available. Clamping the buffer time seems to mitigate the issue a bit.
