Samples request

[dev]

Hello

First, this is not a quality statement post or anything of sorts.
Long time ago i did some listening tests of mine and i also read and listened to other tests and results.
Fortunately or unfortunately i have never been able to hear any artifact at standard preset.
Could someone upload samples where there are artifacts with standard preset?
But please tell me the exact time of the artifact and what to listen for / where to focus.
Please indulge me in this, it is a test of my hearing and curiosity not a codec


Thank You
Pawel
