For my second milestone, I have completed the testing of the components. This included the ESP32, DAC, AMP, and speakers connected. As I said in my video the breadboard is not great for audio and it introduced a considerable amount of interference and feedback that you could audibly hear. Also for this milestone, I was able to finalize the dimensions for the box. Using the software WinISD which is a tuning software for drivers and speaker enclosures. You tune the frequency based on the sound you want. In this case, I have gone for vented as it has much more power in the lower frequencies. All in all this milestone was easier and just time consuming to tune the speaker sounds and box shapes.
