2. We can now take a look at some of the core functions of this sketch:

- `static const char channels = 1;` - sets the number of output channels.
- `static const int frequency = 16000;` - sets the sampling frequency to 20 KHz.
- `static const int frequency = 20000;` - sets the sampling frequency to 20 KHz.
- `short sampleBuffer[512]` - buffer to read samples into, each sample is 16-bits.
- `while (!Serial)` - prevents program from running until Serial Monitor is opened.
- `PDM.begin(channels, frequency)` - initializes the PDM library.
