+clock of the server is a bit faster than our sample clock, it will send out mp3 data faster
+than we process it and our buffer will fill up. Conversely, if the server clock is slower, we'll
+eat up samples quicker than the server provides them and we end up with an empty buffer.
+To fix this, the mp3 logic can insert/delete some samples to modify the speed of playback.
+If our buffers are filling up too fast (presumably due to a quick sample clock on the other side)
+we will increase our playout speed; if our buffers empty too quickly, we will decrease it a bit.
+Unfortunately, adding or deleting samples isn't very good for the audio quality. If you
+want better quality, turn this off and/or feel free to implement a better algorithm.
+WARNING: Don't use this define if you play non-stream files. It will presume the sample clock
+on the server side is waaay too fast and will default to playing back the stream too fast.*/

+/*While connecting an I2S codec to the I2S port of the ESP is obviously the best way to get nice
+16-bit sounds out of the ESP, it is possible to run this code without the codec. For
+this to work, instead of outputting a 2x16bit PCM sample the DAC can decode, we use the I2S
+port as a makeshift 6.5-bit PWM generator. To do this, we map every mp3 sound sample to a
+value that has an amount of 1's set that's linearily related to the sound samples value and
+then output that value on the I2S port. The net result is that the average analog value on the 
+I2S data pin corresponds to the value of the MP3 sample we're trying to output. Needless to
+say, a hacked 6.5-bit PWM output is going to sound a lot worse than a real I2S codec.*/
