I am suddenly experiencing a 'bitcrusher-like' artifact when playing back and interpolating samples.. does anyone have an idea why this could be happening? It happens if I run Csound with sr = 44100 and play back samples of 96kHz, or if I play back samples at a 'non standard' rate (with loscil or loscil3) - sounds like there is no interpolation actually. I am using the latest Csound, and don't think i had this problem at first. I am not experiencing this with any other software.

Hi Søren, Do you have a test CSD and sound file you could post somewhere to test with? Also, could you mention what OS and version of Csound you are using? Thanks, steven On Sat, Feb 24, 2018 at 2:50 PM, sjakops |

Hi Steven, I'm running Win10 and have been using this version of Csound (because I need vst opcodes): https://ci.appveyor.com/api/buildjobs/5eiai835gyy0rd9q/artifacts/msvc%2Fcsound-windows-x64-6.10.0-rc2-1188.exe but the problem was also there after I changed to the official v6.10 release. The following sample score and attached sample do not sound correct on my machine. I've tried with other samples and also with loscil instead of loscil3, and it's the same. |

For info, everything sounds 'correct' on my machine when I use v6.07.0. Is no one else experiencing this problem with v6.10 on windows10/x64? Best regards, Søren On 2/25/18, Søren Jakobsen |

I tested here on Win10 with Csound 6.10 (Dec 21) and I have the artifacts here too. It looks like the output is osccillating between two different signals, as if there is something odd with the interleaving of the stereo signal or that kind of thing.

can you open a issue? A soundfile and CSD to test would be useful. ======================== Prof. Victor Lazzarini Dean of Arts, Celtic Studies, and Philosophy, Maynooth University, Maynooth, Co Kildare, Ireland Tel: 00 353 7086936 Fax: 00 353 1 7086952 > On 27 Feb 2018, at 08:14, Oeyvind Brandtsegg |
