/*Playing a real-time MP3 stream has the added complication of clock differences: if the sample
|
||
|
|
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.*/
