After a few weeks use I will share my experience with the NEW Telinga Stereo mic PIP for Zoom H4n and Olympus LS-XX. This model is still not highlighted at Telingas website http://telinga.com but is made and sold on request. I'm using a Zoom H4n and intend to make recordings in 24bit/96Khz quality (maximum amount of data). The first I found was that the batteries drained out in short time, not more than 1 hour of recording was possible and that was not something I could bring with me out in field! The battery solved: The H4n has a 5V input, and that is not compatible with any normal battery packages! 4x1,5V makes 6V, and 4x1,2V makes 4,8V. BUT 5V is the same as a USB outlet, so I started searching the web for a battery backup for iPad/Mobile phones and I found a 5V/6.6Ah package from DealExtreme in China. So after some cutting and soldering of an old USB-cable and the plug from the Zoom 5V-charger I had a nice battery to plug into my H4n. Later I found a battery box from a mobile phone dealer with 4xAA that has a 5V output. Good as a backup kept warm in your pockets, plug in the USB-plug and go on recording!
12V in your car!
The verdict: Light weight, fantastic performance, no internal batteries, BUT the 3.5mm mic plug requires recorders with PiP (Plug in Power)like the Zoom or Olympus.
Most unwanted low-frequency sounds are easily filtered within Audacity and Tone Control (EQ). This filter can reduce the "noice" (i.e. unwanted Low-Frequency) so the result sounds natural and not like in a tin-box.Test it out with som care!Do not pull the levers all the way down to "0" to keep some of the natural sound-scape.
The Great tit-recording is left unfiltered as it was RAW (24b/48Khz)from the Zoom H4n.
Increased level +3db in Audacity only adjustment. recorded 0500 in the morning at nearly 70 degrees North
