Update:
I finally got the sketch working.. (sorry for the wasted post)..
HOWEVER... all is not lost! I still have a question! LOL
I hear A LOT of noise from the speaker when you are not talking through the mic. How can that be eliminated?

Re: Adavoice/Wave Shield troubleshooting help
There are lots of kinds of noise. Can you describe in detail what you are hearing?
The mic could be picking up 'wind' noise from your breathing - that should go away if you hold your breath for a moment.
It could be vibrations from whatever it is mounted to. Does the noise coincide with movement in any way?
Or it could be electrical interference from other parts of your circuit. This may require re-routing and/or shielding some of your wiring.

It is not wind or talking 'noise'... this is electrical noise.adafruit_support_bill wrote:There are lots of kinds of noise. Can you describe in detail what you are hearing?

It helped (some) to dial down the mic pot on the back.... but there is still some present when the mic is idle (so to speak)..

Re: Adavoice/Wave Shield troubleshooting help
Try re-orienting the wiring. If that alters the noise, you would probably benefit from using shielded and/or twisted pair wiring - especially for the microphone.

Re: Adavoice/Wave Shield troubleshooting help
What wire(s) specially are you referring to?
The electret mic wires you're saying?
Moving the wires themselves doesnt help really... or make a difference.
Also..
I thought (many years) ago.... there was a posted 'volume hack' for the Wave Shield,... to help increase the volume as they are not that loud at full volume
On a side note.... instead of an amp breakout board..... can a power voicebooster/speaker work:

If using the line-out to line-in wire form the speaker OUT to the voicebooster IN?

The microphone wires are the ones most likely to pick up electrical noise.What wire(s) specially are you referring to?
See this thread: viewtopic.php?f=31&t=24201I thought (many years) ago.... there was a posted 'volume hack' for the Wave Shield,... to help increase the volume as they are not that loud at full volume
Yes. You should be able to plug that into the headphone jack on the shield.On a side note.... instead of an amp breakout board..... can a power voicebooster/speaker work:
