Noise Source Diagnosis Agent

The noise source identified and a fix confirmed by a clean test recording

Noise Source Diagnosis Agent: what goes in, what the agent does and what you get

What it does

Finding the source of a noise takes hours of trial and error through the signal chain. This agent works like a careful technician. It asks for short test recordings with each element isolated, such as the interface alone, then the preamp, then the cable and each device. It analyzes the spectrum for hum harmonics at 50 or 60 Hz, hiss or room reflections, and proposes the next test. After each change it compares the new recording with the previous one and narrows the suspects. It stops when the noise falls under the target level or only gear changes remain. Edge case: a hum that appears only when the lights are on points to a dimmer, so the agent asks for a test with the lights off. The user approves any gear purchase or wiring change.

How it works

Follow the arrows from top to bottom. The orange dashed arrow is the loop: when a check fails, the agent goes back and tries again.

Read the steps as a list
  1. User reports a noise

  3. Request a baseline recording with only the interface
  4. Analyze the spectrum for hum harmonics, hiss and reflections
  5. Propose the next isolated test
  6. Did the last change drop the noise by at least 6 dB?If not: record the result, rule out that element and choose the next suspect. Back to step 3.
  7. Name the likely source and a fix
  8. Does a recording with the fix applied meet the target level?If not: narrow the cause further and plan another isolating test. Back to step 3.

How it decides

It picks the next test that rules out the largest group of suspects. A cause is confirmed when removing or changing one element drops the noise by at least 6 dB.

  • Test one element at a time
  • Treat peaks at multiples of 50 or 60 Hz as hum
  • Confirm a cause only with a 6 dB or larger drop
  • Suggest free fixes first, such as cables and power

Make it yours

Every agent is a starting point. You choose these settings for your own situation.

  • Noise target level (default -60 dB)
  • Mains frequency
  • Recording length per test
  • Gear the user can swap

What keeps you in control

It always asks you first

  • Buying or replacing any gear
  • Wiring or grounding changes

Hard limits

  • Never advises opening mains-powered equipment
  • Never recommends purchases before free tests are done

It stops when

  • Done: noise is under target in a test recording
  • Stop: all elements tested and the noise remains

An example run

What happensA podcaster had a hum at 120 Hz. The interface alone was clean. With the monitor on, the hum came back at 62 dB. The agent asked for a test with the monitor on a different outlet. That check dropped the hum only 2 dB, so it was not the outlet. Next the monitor's cable was swapped and the hum fell 14 dB. The user approved buying a new cable.
