Audio question
Recently I have been tinkering with a VCO for the audio indicator of the discriminating detector.
I would like the audio to indicate:
1. FE or non-magnetic target
2. Alu foil and other short TC targets
3. Large sized targets, meaning physical size relative to the diameter of the coil.
4. Targets with a TC longer than 70us
When tinkering with different sine wave and square wave frequencies, I realized that my hearing is just not that good anymore, so I will need help in defining sound variations that are easily distinguished by most of detectorists.
I would welcome suggestions
