* Manually save and restore the FPU rounding mode on WindowsChris Robinson2017-09-192-0/+13
| | | | | | | Apparently there is a bug with at least MinGW-W64 where fegetenv and fesetenv do not properly save and restore the FPU rounding mode, resulting in the rounding mode remaining as round-to-zero after certain function calls. I do not know if this also affects MSVC, but better safe than sorry for now.

* Add a check for pthread_setname_np with three parametersChris Robinson2017-09-153-0/+24
| | | | As found in NetBSD.
* Don't hide -msse and -mfpu=neon checks behind a not-msvc checkChris Robinson2017-08-301-21/+20
| | | | | Apparently Clang gets reported as being MSVC on Windows, but still needs the GCC switches to enable SSE code generation.

|
* Avoid some extraneous load callsChris Robinson2017-08-302-26/+23
| | | | | This likely doesn't change anything given a working optimizer, but it cleans up the code some.
* Automatically generate the bsinc table when buildingChris Robinson2017-08-285-6718/+434
| | | | | This makes bsincgen a native tool like bin2h, so it can run automatically when compiling.

|
* Add a higher quality bsinc resampler using 24 sample pointsChris Robinson2017-08-278-23/+1342
| | | | | | | This improves the transition width, allowing more of the higher frequencies remain audible. It would be preferrable to have an upper limit of 32 points instead of 48, to reduce the overall table size and the CPU cost for down- sampling.

|
* Remove the -m command from makehrtfChris Robinson2017-08-201-44/+15
| | | | | It only ever outputs mhr files, so there's no need to have a command for it. If another output format is ever made, it can be a normal option flag.
* Properly add getopt.c to makehrtfChris Robinson2017-08-201-2/+3

* Use getopt to handle options in makehrtfChris Robinson2017-08-205-72/+260
|
* Improve unicode handling for makehrtfChris Robinson2017-08-202-1/+86
| | | | | | | Command line parameters and filenames are now unicode-aware (the .def files should be UTF-8 encoded, if they contain any non-ASCII-7 characters). Unicode characters might not display correctly in the console, but it should process them correctly.

* "Unfix" the filter length calculationChris Robinson2017-08-181-3/+3
| | | | | | | | Partially reverts 3f3a3ac4f1d069542ca2399a8b5e63d9d1a4df3b. The l*2 + 1 is correct when you want an odd number of sample points, which avoids an unnecessary phase offset in the fitler. However, the rounding is still needed to calculating the left offset (l), or else the transition width can increase with an odd-numbered order.
* Keep bsinc filter quality more consistent between scalesChris Robinson2017-08-172-551/+553
| | | | | | | This generates the filters using the proper size and scale. The 'a' divisor should represent the +/- sample range (and thus be a whole number), with the number of sample points being double that. Increasing the filter size to a multiple of 4 (for SIMD) can be done by padding in 0s afterward.

* Properly calculate the filter sizeChris Robinson2017-08-171-3/+4
|
* Correct the bsinc filter orderChris Robinson2017-08-172-969/+970
| | | | | | Despite the claim that it was an 11th order filter, the transition width was generated by specifying 12th order. A 12th order filter would need 14 sample points rather than the 12 it had.
