e9505b164e
Fix source sends' initial HF absorption and decay calculation
...
The HF absorption is applied given the source distance, as relative to the
source's immediate environment, with additional absorption being applied given
the room/reverb environment. This does double up the amount of absorption
compared to the dry path, but it can be assumed the initial reflections travel
a longer distance.

Use normal air absorption for the sends
...
Applies just for the normal air absorption which uses the air absorption
factor, not the automated decay applied when WetGainAuto is enabled.
2017-05-27 03:40:52 -07:00
c4ef7399f8
Add a new compressor/limiter
...
This is just for the output limiter right now, but in the future can be used
for the compressor EFX effect. The parameters are also hardcoded, but can be
made configurable after 1.18.

653f0a1405
Fix handling chorus and flanger LFO displacement offset
...
The phase offset is modulo-wrapped rather than masked, so it's best to avoid
negative offsets.
2017-05-26 09:09:35 -07:00
2b14c1d623
Properly handle the chorus and flanger LFOs
...
The effects' specified delay is the average delay time, meaning the delay
offset should move between -n and +n relative to the delay, where n <= delay.

a306407b67
Apply more proper air absorption to the wet path
...
This properly accounts for the room rolloff factor for normal air absorption
(which makes it none by default, like distance attenuation), and uses the
reverb's decay time, decay hf ratio, decay hf limit, and room air absorption
properties to calculate an initial hf decay with the WetGainAuto flag. This
mirrors the behavior of the initial distance decay.

Reorganize some code to have fewer temporaries

Add an env var to specify a default pulse device
...
Some apps don't allow selecting an audio device, and due to problems with KDE,
PulseAudio isn't allowed to move the stream after being created by default.

Update a couple comments about the reverb modulation
2017-05-13 16:08:45 -07:00
0b66b2bbe7
Replace 4 separate all-passes with one vector all-pass
...
Each 4 related all-passes now share a structure with one delay line, which uses
an interleaved sample history. Also fixes some potential rounding problems for
delay lines with interleaved samples.
2017-05-13 15:45:05 -07:00
87d4710bc4
Apply reverb modulation to the late feedback lines
...
This seems to be more in-line with the intended behavior, to allow build-up and
overlap within the reverb decay, rather than a pitch-shift on input.
Unfortunately there's no readily available implementation of this reverb model
that includes modulation to compare with, so a low depth coefficient is used to
keep it very subtle.
2017-05-12 20:53:14 -07:00
d456c799fd
Remove the 0.5 gain on the reverb output
...
Turns out to be unnecessary, as it reduced the volume below what other reverb
implementations provide with the same presets.
2017-05-11 23:26:29 -07:00
685dc24299
Restore the previous reverb B2A and A2B matrices

Update ALC_OUTPUT_LIMITER_SOFT to handle ALC_DONT_CARE_SOFT
...
Essentially just adding a comment about it. Since we default to on, the
behavior already fit.

a2c25378a9
Reduce LIMITER_VALUE_MAX
...
The previous value couldn't actually be expressed as a float and got rounded up
to the next whole number value, leaving the potential for an overrun in the
squared sum.
2017-05-09 11:56:03 -07:00
4a4442ad91
Store the output limiter values as fixed-point integers
...
This helps keep the squared sum stable over larger updates, also avoiding the
need to keep recalculating it.
