After I posted about testing voice recording on the iPod touch, faithful TUAW reader Zach did a bit of hunting around the Internet. He discovered that the iPod accessories communicate using a special accessory protocol and that it may be necessary for the iPod touch to talk to the device properly and tell it to boost its gain while recording voice.

Here are a few of the links he found about this accessory protocol. If any of you have further experience in this arena and can make suggestions on how to try to tell a MicroMemo to increase its gain from an iPhone platform, please chime in in the comments.
