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
|
|
|
|
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
|
|
|
|
0.2 :(Oct 27, 2003) added mixed radix, only radix 2,4 optimized versions
|
|
|
|
0.1 :(May 19 2003) initial release, radix 2 only
