Subject[Csnd] Sound artifact
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.

Best regards,
Søren

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

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.



-o dac


sr = 44100
ksmps = 32
nchnls = 2
0dbfs  = 1
instr 1
al, ar loscil3 1.0, 1.2, 123, 1
outs al, ar
endin


f 123 0 0 -1 "test123.wav" 0 0 0
i 1 0 2

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?

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.
Screenshot of the output here:
