## Questions & Answers

**Q: Is there antes sample code and usage of compatible audio libraries? I’m most interested in capturing voice and streaming over http to do voice rec**
A: There are a few. Marcel something on YouTube has a few videos explaining this particular module. The different audio codecs confused me a little at first. This module uses the Es8388 instead of AC101. There need to be more videos explaining the difference between the two codecs. Maybe an idea for a video particularly on the es8388 codec and setup. I tried using the Expressif Tools but my Chinese isn’t the greatest. These boards make great audio workstations with a little Programing experience anyone can get these up and running.
