Hello gentlemen,
Following the instructions of sites like http://art.simon.tripod.com/stealth.html and http://forums.minidisc.org/index.php?showtopic=11254 , I decided to try to build these binaural microphones to make some field recordings.
I already had here some screened cable with a female 3.5mm jack on one end and a male jack on the other, that I had been using as an extension cable for my headphones, all I needed was the mic capsules that I found in my local electronics shop.
I proceeded to mount it as follow:
1. Pick one capsule and mark it as Left and mark the other one as Right.
1.1. Splitted the cable.
2. Solder the Red wire on the V+ spot of the right mic and the bare wire on grown spot.
3. Solder the Black wire and Bare wire to the corresponding spots of the left mic.
4. Plugged the assembly in the mic-in of my desktop's Creative Soundblaster Live sound card. Opened the corresponding software to monitor the captured sound.
5. Trouble: The mic only captured sound from the left side ("left" mic + black/bare wire)
6. I started to think there might have been a problem with the right mic so I desoldered the wires and soldered the right side wires to the "left" mic and the left wires to the "right" mic.
7. Once again, I only captured sound from the left side which lead me to conclude that both mics were functioning but that I was only getting sound from the left side cable.
Here is a pic:
Now, can someone try to explain why is this happening, please?
Thanks in advance for your help,
Kind regards,
Francisco
