Sound into digital recorder comes out mono -- need stereo

[lawyervon]

I'm using a Olympus WS-210S digital recorder -- WS-210S -- to record some voice work. It's a stereo recorder.

I'm also using a Radio Shack hands-free tie-clip microphone -- Hands-Free Tie-Clip Omnidirectional Electret - RadioShack.com -- plugged into the microphone jack of the digital recorder. I'm thinking this may be a mono microphone.

After recording, the resulting audio is in mono only. How do I fix this? Is there an adapter I can put between the microphone and the recorder that will record input from the microphone in stereo?

To record in stereo you'll need two microphones. Normally when you plug in an external mike it disables the internal ones.
So you'll need a stereo to L/R splitter. Something like a stereo mini phone plug to two mono mini phone jacks. Something like this thing...

Would it be better to go with a stereo tie clip microphone instead? Radio Shack doesn't seem to have one, but I found a Sony -- Sony ECM-CS10 Tie Clip Stereo Microphone ECMCS10 -- and a Olympus -- Olympus ME-51S Stereo Tie Clip Microphone -- on a quick Google

Why would you need stereo to record one voice? Just record it mono and play it back through two channels if you want to use two speakers.
