This can have fairly linear speedups for larger FFT sizes. - -1.2.7 - Shrank the real-fft memory footprint. Thanks to Galen Seitz. - -1.2.6 (Nov 14, 2006) The "thanks to GenArts" release. - Added multi-dimensional real-optimized FFT, see tools/kiss_fftndr - Thanks go to GenArts, Inc. for sponsoring the development. - -1.2.5 (June 27, 2006) The "release for no good reason" release. - Changed some harmless code to make some compilers' warnings go away. - Added some more digits to pi -- why not. - Added kiss_fft_next_fast_size() function to help people decide how much to pad. - Changed multidimensional test from 8 dimensions to only 3 to avoid testing - problems with fixed point (sorry Buckaroo Banzai). - -1.2.4 (Oct 27, 2005) The "oops, inverse fixed point real fft was borked" release. - Fixed scaling bug for inverse fixed point real fft -- also fixed test code that should've been failing. - Thanks to Jean-Marc Valin for bug report. - - Use sys/types.h for more portable types than short,int,long => int16_t,int32_t,int64_t - If your system does not have these, you may need to define them -- but at least it breaks in a - loud and easily fixable way -- unlike silently using the wrong size type. - - Hopefully tools/psdpng.c is fixed -- thanks to Steve Kellog for pointing out the weirdness. - -1.2.3 (June 25, 2005) The "you want to use WHAT as a sample" release. - Added ability to use 32 bit fixed point samples -- requires a 64 bit intermediate result, a la 'long long' - - Added ability to do 4 FFTs in parallel by using SSE SIMD instructions. This is accomplished by - using the __m128 (vector of 4 floats) as kiss_fft_scalar. Define USE_SIMD to use this. - - I know, I know ... this is drifting a bit from the "kiss" principle, but the speed advantages - make it worth it for some. Also recent gcc makes it SOO easy to use vectors of 4 floats like a POD type. - -1.2.2 (May 6, 2005) The Matthew release - Replaced fixed point division with multiply&shift. Thanks to Jean-Marc Valin for - discussions regarding. Considerable speedup for fixed-point. - - Corrected overflow protection in real fft routines when using fixed point. - Finder's Credit goes to Robert Oschler of robodance for pointing me at the bug. - This also led to the CHECK_OVERFLOW_OP macro. - -1.2.1 (April 4, 2004) - compiles cleanly with just about every -W warning flag under the sun - - reorganized kiss_fft_state so it could be read-only/const. This may be useful for embedded systems - that are willing to predeclare twiddle factors, factorization. - - Fixed C_MUL,S_MUL on 16-bit platforms. - - tmpbuf will only be allocated if input & output buffers are same - scratchbuf will only be allocated for ffts that are not multiples of 2,3,5 - - NOTE: The tmpbuf,scratchbuf changes may require synchronization code for multi-threaded apps. - - -1.2 (Feb 23, 2004) - interface change -- cfg object is forward declaration of struct instead of void* - This maintains type saftey and lets the compiler warn/error about stupid mistakes. - (prompted by suggestion from Erik de Castro Lopo) - - small speed improvements - - added psdpng.c -- sample utility that will create png spectrum "waterfalls" from an input file - ( not terribly useful yet) - -1.1.1 (Feb 1, 2004 ) - minor bug fix -- only affects odd rank, in-place, multi-dimensional FFTs - -1.1 : (Jan 30,2004) - split sample_code/ into test/ and tools/ - - Removed 2-D fft and added N-D fft (arbitrary) - - modified fftutil.c to allow multi-d FFTs - - Modified core fft routine to allow an input stride via kiss_fft_stride() - (eased support of multi-D ffts) - - Added fast convolution filtering (FIR filtering using overlap-scrap method, with tail scrap) - - Add kfc.[ch]: the KISS FFT Cache. It takes care of allocs for you ( suggested by Oscar Lesta ). - -1.0.1 (Dec 15, 2003) - fixed bug that occurred when nfft==1. Thanks to Steven Johnson. - -1.0 : (Dec 14, 2003) - changed kiss_fft function from using a single buffer, to two buffers. - If the same buffer pointer is supplied for both in and out, kiss will - manage the buffer copies. - - added kiss_fft2d and kiss_fftr as separate source files (declarations in kiss_fft.h ) - -0.4 :(Nov 4,2003) optimized for radix 2,3,4,5 - -0.3 :(Oct 28, 2003) woops, version 2 didn't actually factor out any radices other than 2. - Thanks to Steven Johnson for finding this one. - -0.2 :(Oct 27, 2003) added mixed radix, only radix 2,4 optimized versions - -0.1 :(May 19 2003) initial release, radix 2 only |
