Demonstration of a first working version of a sampler application for the ESP32 WROVER board. This version will sample 30 seconds of single channel (left / right) audio with a samplerate of 32000. Then, the demo will automatically switch to looped playback of the sampled content.
I'm using the ESP-WROVER-KIT from espressif and the Teensy audio board with the SGTL5000 codec.
Most pins are defined in the sgtl5000 header file.
