Power line hum getting into the recording system. 5. Acoustic hum from florescent lights. 6. Noise from photocopier drum warming getting into the power circuit with chirps every 12.6 seconds. I think Fons is onto something, find the cases for noise reduction, study the noise content, and devise or apply a suitable noise algorithm. For my above cases Audacity's noise reduction is useful. I'm not in a high fidelity situation.
