MicrophoneEx is PAlib add-on for high-quality microphone recording.

It is a simple library intended to replace PAlib’s current microphone functions. Currently it is capable of:
– Recording high-quality sounds from the microphone
– Tell the user the microphone’s volume (very much like PAlib)
– Writing microphone recordings to WAV files on the flash card

Also, please note that it only works with PAlib 080823 (latest PAlib version as of 30/08/2008).
