55e3b840b3 Reduce the default period count to 3 2017-02-22 15:56:09 -08:00

2e1f1449bc Don't remove a period from the OSS buffer 
Since we're now waiting for space to be available before mixing, the mixing
buffer isn't adding another period.

2dd142fed0 Make the "sends" config option act as a limit 
Instead of forcing the device to always use the specified send count, it simply
limits requests to it.

d3cc867bd4 Increase the default effect slot and send count 
The default number of auxiliary effect slots is now 64. This can still be
raised by the config file without a hard maximum, but incurs processing cost
for each effect slot generated by the app.

The default number of source sends is now actually 2, as per the EFX docs.
However, it can be raised up to 16 via ALC_MAX_AUXILIARY_SENDS attribute
requests, rather than the previous 4.

cd24e42b3f Make the voices' Send[] array dynamically sized 
The voices are still all allocated in one chunk to avoid memory fragmentation.
But they're accessed as an array of pointers since the size isn't static.

5a2ef2590f Allow distance compensation for non-HQ rendering as well 
It still requires a custom configuration to specify appropriate speaker
distances.

b23f81b686 Remove the separate surround51rear decoder option 
Both 5.1 Side and Rear configurations use 'surround51' to look up the
appropriate decoder file. The decoder loader already handles mapping between
rear and side channels, so there's no need for separate options.

d45dd9c668 Remove the sinc8 resampler option 
Perf shows less than 1 percent CPU difference from the higher quality bsinc
resampler, but uses almost twice as much memory (a 128KB lookup table).

2448f88e70 Return some device latency by default 
A device will never have 0 latency. OpenAL Soft itself uses a sample buffer
length of UpdateSize*NumUpdates, and during playback will have about
(NumUpdates-1) periods filled, more or less. Without a more accurate
measurement from the playback system, this is better than reporting 0.

909193a345 Reorganize ALvoice members 
This places the Send[] array at the end of the struct, making it easier to
handle dynamically.

5a50c46c22 Make ALsourceProps' Send array dynamically sized 
ALsourceProps' Send[] array is placed at the end of the struct, and given an
indeterminate size. Extra space is allocated at the end of each struct given
the number of auxiliary sends set for the device.

0d19a20901 Make the source state atomic 
Since it's modified by the mixer when playback is ended, a plain struct member
isn't safe.

3cc88b0aab Use an all-pass series on each late reverb line 
This attempts to improve the smoothness of the late reverb decay by passing
each line through multiple all-pass filters. Some work is still needed to work
better in high-density and not-so-high-diffusion environments.

This also removes the decay from the early reflections, since it's no longer
continuous feedback.

1ebfce4cac Improve the ambisonic upscaling methods 
This now takes advantage of the differences seen in generated decoder matrices
for first-order compared to second- and third-order, such that with the
appropriate frequency-dependent scaling applied to first-order content, the
result is identical with a higher-order decoder matrix compared to a first-
order matrix for the same layout.
