4cd3f0bf9f Added Second Order Sections filterbank. Works much better that Fir filterbank. Does not need decimation. Easy generation of filters with scipy.signal.butter. 2020-01-03 21:11:56 +01:00
195319ab29 Added the possibility to shift to different fft backend. Now set to fftw. Seems to work properly 2019-12-29 22:07:27 +01:00
a39d8300a1 Somewhere inbetween. Everything broken 2019-12-08 14:19:10 +01:00
3c0562cee4 Renamed nominals to nominals_txt 2018-09-21 09:16:58 +02:00
1b21cc1873 Partially done implementation of Octave and one-third octave filterbank. 2018-06-14 14:49:14 +02:00
ce7f31ca86 Renamed lasp_math.h to lasp_mat.h as it defines matrices, not math. Made a typedef from vd to dmat such that the types of these are the same. Same goes for vc and cmat 2018-04-01 14:01:07 +02:00
f37ce6b596 Fixed bug in filtebank, renamed ASCEE to LASP in lasp_python.h, added decimator. 2018-03-04 19:48:46 +01:00
53a60877b4 Cleanup fir filter design code. Removed Beamforming reference i test_fft.py 2018-02-27 19:45:21 +01:00
c55d3b1e17 Rename all beamforming to lasp. In all source code. 2018-02-23 20:40:45 +01:00
ad6c3213cd Added filterbank and toebehoren 2018-02-19 10:40:28 +01:00
aa3935a82b Fixed bug in print_dmat and print_cmat, allow for empty dmats and cmats in some part of the code. Added dmat_foreign_vd. Some minor improvements in code and docs. WARN and DBGWARN now print to stdout instead of stderr, as Spyder taps the stderr. Improved the dFifo to handle memory better. Now dFifo does not have a maximum size anymore. Renamed Fft_alloc to Fft_create. 2018-02-19 10:37:08 +01:00
008876dbab Added inverse FFT code. 2018-02-17 17:01:53 +01:00
54e9eeca37 Changed internals of xmat to use strides instead of column pointers. Some other bugfixes 2018-02-12 20:44:07 +01:00
85636ce946 Changed Fft API to also be able to compute for one channel 2018-02-10 21:14:17 +01:00
89e9622b1f Bugfix, added overflow checks for debug mode. Tested AvPowerSpectra. Now works without errors, only addTimeData cannot be called twice. Improved fft implementation. Removed double wrapper for fftpack. Renamed fft.pyx to wrappers.pyx. Improved CMakeLists. Adde proper function entrance and exit tracers. Made tracers indent to function level. Added Bartlett window function 2018-02-09 11:56:49 +01:00
83aaf69bef Refactoring math routines. Added comments. Removed multithreading from fft routines. Switched to fftpack for FFT. Added Doxyfile 2018-02-06 12:01:27 +01:00
52e5a31bdb Initial commit. Lots of stuff 2018-01-29 16:14:50 +01:00
