SynthAnthony Posted October 19, 2016 Report Share Posted October 19, 2016 I has been a while since I used my sammichSID for anything other than just messing around, but I decided to record a small 8bit SFX library. I never noticed a noise issues before, but after some recording and editing, I can say that it is at unacceptable levels. I get around -45dB FS of noise when, while most samples reach peak -10db FS. Surely it can do better than that. What might be the issue? It has 2x 6852 chips. I'm using RME UCX for recording. Quote Link to comment Share on other sites More sharing options...
jaytee Posted October 21, 2016 Report Share Posted October 21, 2016 Is your external input tied to ground? On a sammichSID, the input is a switching jack, so if there's nothing plugged in, it *should* tie to ground automatically, if it hasn't developed a soldering fault. If there's anything plugged into that jack....unplug it! It might also be the VCA leakage. I've noticed that some patches tend to leak worse than others. A bad/noisy power supply can also cause noise issues. 1 Quote Link to comment Share on other sites More sharing options...
