IOW so you are always recording the last 30 seconds and can play back the 'last 30 seconds' at any time? or is it strictly "record" then "playback"?</p>

Please see the short <a href="http://www.youtube.com/watch?v=l1pEsq4mwgo" rel="nofollow">video clip</a>. Wish I had recorded the audio better as this board produces excellent audio; I choose the configuration resistor for maximum fidelity.<p>I'm surprised that there seems to be nothing on the market for people with expressive aphasia. It would be easy to make a box with 8 short messages.</p></p>

The complete writeup, including wiring diagram is on my blog:<a href="http://baldwisdom.com/electrify-your-halloween-making-things-scream/" rel="nofollow">http://baldwisdom.com/electrify-your-halloween-making-things-scream/</a>
I also started a simple arduino library for it:

A closer look at the schematic shows that the "negative" leg of the mic is tied to "LED" which is an output of the 1932. "LED" is active low so when recording (the red LED is lit), the mic operates like a single-ended mic. But when not recording, the mic is ineffective because "LED" is driving high...which is why it doesn't work in feedthrough mode.</p>

I can only record if the line out jack is not connected (no biggie, but might help others looking at this board). I can start & stop play, no problem. But the 1932 spec sheet says feed-through only for single ended audio! The board had a differential mic glued down. I can't get feed-through to work. Is it because the differential mic is present? Has anyone gotten feed-through to work with this board? Do I need to lift the capacitors and solder down a single ended mic to get feed-through to work? If so, this should still allow muxing between the recorded audio and the single ended mic? So close to finishing my project! Any help is very much appreciated! :-)</p>

Perhaps a description of the pinout from the board?
I'm hoping to create a voice module with best quality audio, one message, of 20 seconds duration.
Thanks!

May I suggest a couple of through-hole points on the mic-connections, coupled with designated places to cut the traces for the built-in mic?</p>

I am not sure what the sample frequency is that the sample is, but a single resistor change with this part can increase or decrease the frequency... just look at the datasheet for the chip. Also, the LED pin should be connected to the microphone input, it is a technique they use to disable the microphone when its not in record mode.</p>

I have one, but I can't seem to get it to record. Feedthrough mode doesn't work (tying it to low doesn't output the audio to the speakers). And the LED pin is always on.</p>
