Audio Spectrum Analyzer ("Spectrum Lab")

[nelson]

Hi, searching the net, i found the program show on the link below.
This program can convert your pc into an ulf and vlf receiver, just by conecting the apropiate antena thru the mic conector of your sound card.
I think this can be useful for made some experiments on the spectrum that metal detectors and long range detectors works.

Hi nelson,

this is also very interesting to cover higher frequency ranges.

Aziz,

I have used Spectrum Lab in the past for looking at the signal on the TINKERERS and found it very useful, even when I used only very few of the DSP functions of it.

Could you tell me how to adapt the mono microphone input of my laptop so that I can input stereo, In this case it would be the gold channel of the TINKERERS right and the iron channel left?

Thanks

Yes, very useful. All Scope (hardware or even software pc scope) with FFT math analysing feature can do this presentation of the frequency spectrum.

I specially like the DSP. There is a lot of filtering that can be done.
