I've been searching around and looking at different solutions but I can't quite seem to find what I need. I'm trying to build a device that can record for long periods (up to 30 mins) of voice (low quality is fine) and play it back. The idea is to create customizable prompts and have users speak into the device to respond.
I've seen mp3 shields and audio shields that provide playback from an (micro)SD card and then audio recording breakout boards that can record audio and I've also search the forums for similar projects.
What I'm seeing are boards that can record for 1-2 minutes max, and I wanted to know if it were feasible to record for up to 30 minutes.
Any insight would be greatly appreciated!
