* "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 Robinson2017-08-171-7/+9
| | | | | | | 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 Robinson2017-08-171-6/+7
| | | | | | 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.
* Make the sinc4 table staticChris Robinson2017-08-161-1/+1

* Make the bsinc table layout more efficientChris Robinson2017-08-161-99/+20
| | | | | | | | | | | | | | | | The old layout separated filters, scale deltas, phase deltas, and scale phase deltas into separate segments that each contained a numbers of scale and phase entries, Since processing a sample needed a filter and one of each delta entry relating to a particular scale and phase, the memory needed would be spread across the whole table. And since subsequent samples would use a different phase, it would jump around the table a whole lot as well. The new layout packs the data in a way more consistent with its use. The filters, scale deltas, phase deltas, and scale phase deltas are interleaved, such that for a particular scale and phase, the filter and delta entries used are contiguous. And the phase entries for a particular scale are kept together, so the ~500 to ~1000 samples processed per source update stay within the same 3KB to 6KB area of the 70+KB table, which is much more cache friendly.
* Keep bsinc info together in a structChris Robinson2017-08-151-37/+61

* Add experimental support for 24-bit, dual-ear HRTFsChris Robinson2017-08-081-8/+42
| | | | | | | Currently makehrtf only handles 24-bit output, not dual-ear, and only when given the --experimental switch. Files produced this way will not be guaranteed future compatibility. When the mhr format is also updated with multi-distance measurements, the experimental switch can go away.
* Replace makehrtf's ditherChris Robinson2017-08-011-14/+22
| | | | | This uses a custom RNG instead of relying on the system-dependent rand(). It also removes the high-pass/noise-shaping, to flatten the noise floor.
* Update makehrtf to use a larger FFT by defaultChris Robinson2017-07-251-74/+60
| | | | Also fixes DC offset removal and increases the max IR size.
* Resample HRIRs prior to minimum phase reconstructionChris Robinson2017-06-011-36/+41

* Rename stereo-panning option to stereo-encodingChris Robinson2017-02-222-19/+21
| | | | Also rename the 'paired' value to 'panpot', and make it the default.
* Reduce the default period count to 3Chris Robinson2017-02-221-1/+1
|
* Make the "sends" config option act as a limitChris Robinson2017-02-211-18/+5
| | | | | Instead of forcing the device to always use the specified send count, it simply limits requests to it.
* Increase the default effect slot and send countChris Robinson2017-02-212-5/+5
| | | | | | | | | | 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.
* Allow distance compensation for non-HQ rendering as wellChris Robinson2017-02-203-13/+3
| | | | | It still requires a custom configuration to specify appropriate speaker distances.
* Remove the separate surround51rear decoder optionChris Robinson2017-02-193-55/+9
| | | | | | 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.
* Remove the sinc8 resampler optionChris Robinson2017-02-192-11/+11
| | | | | 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).
* Replace range-based for loops with QList iteratorsChris Robinson2017-01-131-8/+8
| | | | Less than ideal, but some targets can't rely on C++11
* Search for and use Qt5 for alsoft-configChris Robinson2017-01-121-13/+36
| | | | An option is provided to instead use Qt4.8 still if desired.
* Use C++11 for alsoft-configChris Robinson2017-01-121-8/+8

* Rename the version target for systems that have a version libChris Robinson2016-12-211-2/+2
|
* Avoid duplicate HRTF entries in the UIChris Robinson2016-12-211-2/+11
| | | | | | Similar to how the library handles it, duplicate entries of the same file are ignored. This could happen if, for example, XDG_DATA_DIRS contains the same path multiple times.

| * Use GNUInstallDirs to place the build artifacts properlyMarcel Metz2016-09-061-3/+3
| | | | | | | | | | | | | | | | CMake 2.8.5 added the GNUInstallDirs module, which provides various variables following the CMAKE_INSTALL_*DIR pattern to allow users a more flexible installation setup and to provide sensible defaults while respecting distribution specific install locations like lib64 for RPM based linux distributions or debian multiarch tuples.
