There have been some important fixes since it was built. > When the conversion is done, and no errors here, and I > try to play the new file , I get 1 sec high frequency noise from my > DAC chord 2qute and playing stops. The high-frequency noise in the DSD128 input is destabilising the modulator. You need to get rid of it with a low-pass filter. Something like this will do: $ sox dsd128.dsf dsd64.dsf lowpass 50k rate -v 2822400 sdm For a sharp cut-off, use the sinc effect instead of lowpass. The exact frequency isn't important, so you might want to experiment a bit. -- = M=E5ns Rullg=E5rd ---------------------------------------------------------------------------= --- Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Sox-users mailing list Sox-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/sox-users
