To test this release unpack and run "make test" you will need libfftw3 (fftw3-devel if you use packages) installed to test, but not to use, typically test results should look like: ----------------------------- 8< ---------------------------------- baseline 24 in 32 test, 1024 samples took 40.3 cycles/sample Optimised: GDitherNone, 1024 samples, 24 in 32bit took 48.7 cycles/sample GDitherRect, 1024 samples, 24 in 32bit took 77.3 cycles/sample GDitherTri, 1024 samples, 24 in 32bit took 84.7 cycles/sample GDitherShaped, 1024 samples, 24 in 32bit took 106.2 cycles/sample GDitherNone, 1024 samples, 16bit took 53.7 cycles/sample GDitherRect, 1024 samples, 16bit took 81.8 cycles/sample GDitherTri, 1024 samples, 16bit took 94.8 cycles/sample GDitherShaped, 1024 samples, 16bit took 117.5 cycles/sample Unoptimised: GDitherNone, 1024 samples, 20 in 32bit took 55.2 cycles/sample GDitherRect, 1024 samples, 20 in 32bit took 82.4 cycles/sample GDitherTri, 1024 samples, 20 in 32bit took 93.1 cycles/sample GDitherShaped, 1024 samples, 20 in 32bit took 120.8 cycles/sample GDitherNone, 1024 samples, 24 in float took 32.6 cycles/sample GDitherRect, 1024 samples, 24 in float took 65.3 cycles/sample GDitherTri, 1024 samples, 24 in float took 76.2 cycles/sample GDitherShaped, 1024 samples, 24 in float took 96.1 cycles/sample GDitherTri, 1024 samples, 24 in float, double input took 85.1 cycles/sample RMS SNR for no dithering = -149dB RMS SNR for rectangular dithering = -142dB RMS SNR for triangular dithering = -144dB RMS SNR for noise-shaped dithering = -131dB ok no dithering mean harmonic resonace = 40.4dB no dithering peak harmonic resonance = 47.9dB rectangular dithering mean harmonic resonace = 1.5dB rectangular dithering peak harmonic resonance = -2.7dB triangular dithering mean harmonic resonace = -0.2dB triangular dithering peak harmonic resonance = -2.6dB noise-shaped dithering mean harmonic resonace = 0.8dB noise-shaped dithering peak harmonic resonance = -8.1dB ok random amp/frequecy range = [0.50,0.52] 16bit distribution range = [0.82,1.21] ok checking interleaving ok
