+# Decoding a WAV file
+
+In this example we decode a WAV file into RAW output and let it output using the [Mozzi](https://sensorium.github.io/Mozzi/) output functionality.
+Mozzi is supporting
+
+- AVR
+- ESP32
+- ESP8266
+- SAMD
+- STM32
+- Teensey3
+- Raspberry Pico
+- MBED
+
+This flexibility comes at a price however:
+- you need to configure the AUDIO_CHANNELS in the mozzi_config.h to the right value or provide the number of channels that are currently configured
+- not all processors support all samping rates: it is recommended that you use the sampling rate which mozzi expects (this is available e.g. in AUDIO_RATE)
+
+The WAV file has been down sampled with the help of __Audacity__ and then converted into an array with __xxd__. 
+
+MemoryStream -> AudioOutputStream -> WAVDecoder -> MozziStream
+
+
+## Preconditions
+
+You need to have https://github.com/pschatzmann/Mozzi installed.
