* Handle the delays specified in SOFA filesChris Robinson2022-10-101-44/+55

* Resample before frequency analysisChris Robinson2022-05-131-9/+33
| | | | | | | | | | We want to resample before minimum phase reconstruction since that changes the phase relationship of the sampled signal, introducing a slight bit of noise from truncated sampling. It's not clear that the frequency domain resampling method is accurate, so resampling prior to frequency analysis is an alternative to ensure the resulting frequencies are given the proper phase for sampling. This also cleans up some micro allocations in loops.

* Use multiple threads for magnitude calculationsChris Robinson2020-06-191-30/+71
| | | | Also allow user-declarable thread count.
* Calculate the HRIR onsets and magnitudes separately from loadingChris Robinson2020-06-171-21/+82
| | | | | This should help improve memory use a bit since the SOFA file can be unloaded before allocating some temp buffers for onset detection and FFT calculation.
* Avoid reinitializing the resampler with each HRIRChris Robinson2020-06-171-10/+11

* Use the peak IR magnitude to get the onsetChris Robinson2020-01-251-7/+3
| | | | | | | | | | | | While maybe not technically correct, we actually only care about the difference between onsets (any base constant is removed). This should work better since it determines when the IR is most audible, whereas previously it used a variable threshold of when it reached 15% of the max amplitude. An even better method may be to check where the IR amplitude exceeds a fixed threshold (i.e. the same threshold applied to all IRs), but that would need tweaking to find a level that doesn't catch random noise and doesn't potentially miss the more occluded IRs.

* Support loading SOFA files directly with makemhrChris Robinson2019-03-251-0/+649
| | | | | | | This extracts the definition info it can from the SOFA, and uses the same logic as sofa-info to automatically detect an appropriate layout. There is a bit of code duplication from loaddef.cpp and sofa-info.cpp, though there are slight modifications.
* Move makemhr's .def loading code to a separate sourceChris Robinson2019-03-241-0/+4
