Hi there, I was wondering if anyone could give my .csd a listen and
tell me if they're hearing the same artefacts that I am. I have also
attached a .mp3 of what I can hear, which I have listened to on
another device to make sure the artefacts are indeed in the audio
file.

I'm making some kick sounds, and noticed some unwanted artefacts that
happen during the decay period.

I've tried changing the sr, which makes the artefacts higher, which
made me think that it might be aliasing caused by FM to start with,
but I've removed everything but a simple sine oscillator, so it can't
be aliasing. I've also tried linseg instead of expseg to see if it
made a difference, and with longer decay times, it seems to go away,
but with quick decay times, it is present again.

I am currently using a £30 soundblaster soundcard at the moment,
because the jack socket on my laptop broke and I couldn't afford
anything better at the time, so I am wondering if the soundcard might
be at fault here, as I have also heard artefacts in pre-recorded music
by other people that don't sound like they should be there.

the artefact is also in the example. It depends on the ksmps value you are using. If you replace 

aosc oscili kampenv, icps

by 
aosc oscili a(kampenv), icps

it’s gone

cheer,s
