Ok I’ll try to explain my problem the best I can. Please know that I’m not a technician so maybe I’m not using the right words.
I do audio recording with Audacity in my evangelical church in Rome (http://www.chiesaolgiata.org). We record usually sermons. So basically it’s all voice recording. Now…we’ve had some electricity problems lately but it seems all is ok now.
Recently we had this problem: there was like a “static noise” in our recordings. You could hear it just plugging in the audio jack into the laptop (that jack comes from a mixer). It immediately sounded like ZZZZZZZZZZZZZZZZZzzzzzzzzzzzzzZZZZZZZZ.
After some trys we descovered something I have no idea about if we unplug the AC from the laptop and use battery only the noise stops and recording goes just perfect. You only hear the voice of the preacher and that’s it. Just perfect! As you plug the AC from the laptop back again this buzz starts again.
Some questions:
- Why does that happen?
- How can we fix it?
I understand that it’s NOT AN AUDACITY problem but a hardware problem. But I have no idea where to ask this. Anyone can help me out or just give me a link to a more appropriate forum?
Regards.
