9ac8f25a05 Ignore direct channels for mono and B-Format buffers 2019-12-29 19:17:29 -08:00
Chris Robinson
701d43b41e Start a new extension for a new direct_channels state 
So existing behavior remains consistent for anything that needs it, and new
behavior is opt-in.

2e6a55a87c Handle padding between device sample frames 
The padding must be constant and sample type aligned (e.g. some fixed multiple
of two bytes between the start of two consecutive frames for 16-bit output).
The intent is to always have the ability for stereo output with WASAPI even if
the device has some other unsupported configuration, as long as front-left and
front-right exist.

54e7f48df9 Use unique setters for biquad filter parameters 
One for whether a slope parameter is used, and one for bandwidth.

0a65ed2190 Use normal panning for B-Format output 
It can never work since it only uses auxiliary channel labels.

58e4d643d3 Make B-Format rotation more robust 
This should now handle higher orders, and can be easily extended to non-FuMa
layouts and scalings.

882b4acae8 Add "fast" variants for the bsinc resamplers 
This simply omits the scale factor from the filter, similar to how up-sampling
does. The consequence of this is less smooth transitions when ramping the
pitch while down-sampling, but otherwise behaves fine.

9b64e5e0db Implement a "fast" bsinc path 
This takes advantage of the fact than when increment <= 1 (when not down-
sampling), the scale factor is always 0. As a result, the scale and scale-phase
deltas never contribute to the filtered output. Removing those multiply+add
operations cuts half of the work done by the inner loop.

Sounds that do need to down-sample (when played with a high pitch, or is 48khz
on 44.1khz output, for example), still go through the normal bsinc process.

3154a915b1 Remove the ReverbSpeedOfSound hack 
No other effect depends on context or listener properties, so reverb being the
only exception for speed of sound and meters per unit was putting extra work on
the effect engine for no real reason. Especially since the reverb decay time
should be the time actual time to decay irrespective of other settings.
