* Rename Uhj2Encoder to UhjEncoderChris Robinson2021-04-012-5/+5

* Avoid passing an array of pointersChris Robinson2021-04-012-26/+30
|
* Add support for 4-channel UHJChris Robinson2021-03-312-8/+12
| | | | Also add the SOFT moniker to the new macros
* Decode UHJ buffers to B-Format for mixingChris Robinson2021-03-314-6/+100
| | | | | This should also have an adjustment for the shelf filter. Although it's not clear what the appropriate adjustments should be.
* Rename a couple class membersChris Robinson2021-03-282-12/+12

* Remove some unnecessary includesChris Robinson2021-03-281-6/+0

* Move the UHJ phase shifter to a common headerChris Robinson2021-03-282-203/+14

* Update the UHJ decoding coefficientsChris Robinson2021-03-241-2/+5
|
* Fix the UHJ all-pass delayChris Robinson2021-03-202-11/+8
| | | | | | | | | For real this time. The non-all-passed signal needs a one-sample delay over the all-passed signal. Because of the way the all-pass FIR filter is structured, it wouldn't otherwise use the last buffered sample, allowing it to be shifted forward in time by one sample. Also, remove a couple unnecessary buffers.
* Fix UHJ FIR filter alignmentChris Robinson2021-03-151-1/+1

* Avoid cutting off the last bsinc filter coefficientChris Robinson2021-03-011-3/+3
|
* Avoiding cutting all bsinc resampler output at scale 0Chris Robinson2021-02-241-7/+6
| | | | | | | | | | | | This is mostly for the SampleConverter, used by some capture backends. When recording at really low rates, like 5512hz, with a device capturing at a higher rate like 44100hz or 48000hz, it hits the filter's downscaling limit and produces pure silence. In such cases, it's better to just accept some aliasing noise so that the app will still get some recognizable audio. The alternative would be to scale the desired rate by 2x, 3x, etc until it's above the bsinc limit, then take every 2nd, 3rd, etc sample of the result as if by an extra simpler resampler pass.
* Use a more appropriate epsilon for Sinc()Chris Robinson2021-02-241-1/+2

* Avoid an unnecessary loop iterationChris Robinson2021-02-231-2/+3
|
* Adjust the bsinc filter table packingChris Robinson2021-02-234-41/+29
| | | | | | | | Now each scale's filter and phase delta are interleaved for each phase index, followed by the scale and scale+phase delta for each phase index. This ensures no holes in the filter coefficients for the fast bsinc resampler for a given run, while keeping the scale deltas in the same vicinity for the non-fast bsinc resampler.
* Remove unnecessary use of SSE2 intrinsicsChris Robinson2021-02-211-2/+1
| | | | | The compiler is producing the same results either way, since the upper bit results are never used.
* Store the all-pass FIR results more efficientlyChris Robinson2021-02-181-14/+23

* Avoid compiling different sources for different targetsChris Robinson2020-12-134-0/+17
| | | | | | | | Simplifies configuration and fixes a potential problem with inline functions. Inline functions that fail to inline will have a callable body generated. If such a body is generated with the SSE4 source, for example, it can generate SSE4 instructions. Calls for that function in other sources can then end up calling the SSE4-generated body outside of any CPU capability check.
