Step 3: Finish the Connections

Remove the playback button on the recording module by bending back the two tabs on the back.
Solder the two connections coming from the rectifier to the playback contacts.

Pick the audio cable of your choosing (I used a mini female connector on a length of wire with bare leads) and solder the two connections to the speaker terminals on the recording module. This will allow you to directly input audio to the recording module.
