+# Generating Audio with Tensorflow Liete
+
+The starting point is the good overview provided by [the "Hallo World" example of Tensorflow Lite](https://www.tensorflow.org/lite/microcontrollers/get_started_low_level#train_a_model) which describes how to create, train and use a model which based on the __sine function__.
+
+We just send a generated sine wave to the I2S interface. Further information can be found in the [Wiki](https://github.com/pschatzmann/arduino-audio-tools/wiki/Tensorflow-Lite----Audio-Output)
+Please note the log level should be set so that there is no disturbing output!
+
+ 
+### External DAC:
+
+For my tests I am using the 24-bit PCM5102 PCM5102A Stereo DAC Digital-to-analog Converter PLL Voice Module pHAT
+
+![DAC](https://pschatzmann.github.io/Resources/img/dac.jpeg)
+
+I am just using the default pins defined by the framework. However I could change them with the help of the config object. The mute pin can be defined in the constructor of the I2SStream - by not defining anything we use the default which is GPIO23
+
+ 
+DAC  |	ESP32
+-----|----------------
+VCC  |	5V
+GND  |	GND
+BCK  |	BCK (GPIO14)
+DIN  |	OUT (GPIO22)
+LCK  |	BCK (GPIO15)
+FMT  |	GND
+XMT  |	3V (or another GPIO PIN which is set to high)

+- DMP - De-emphasis control for 44.1kHz sampling rate(1): Off (Low) / On (High)
+- FLT - Filter select : Normal latency (Low) / Low latency (High)
+- SCL - System clock input (probably SCL on your board).
+- FMT - Audio format selection : I2S (Low) / Left justified (High)
+- XMT - Soft mute control(1): Soft mute (Low) / soft un-mute (High)
