+    AudioModule
+        A interface to send raw codec2 audio data over the mesh network. Based on the example code from the ESP32_codec2 project.
+        https://github.com/deulis/ESP32_Codec2
+
+        Codec 2 is a low-bitrate speech audio codec (speech coding) 
+        that is patent free and open source develop by David Grant Rowe.
+        http://www.rowetel.com/ and https://github.com/drowe67/codec2
+
+    Basic Usage:
+        1) Enable the module by setting audio.codec2_enabled to 1.
+        2) Set the pins (audio.mic_pin / audio.amp_pin) for your preferred microphone and amplifier GPIO pins.
+           On tbeam, recommend to use:
+                audio.mic_chan 7 (GPIO 35)
+                audio.amp_pin 25 (GPIO 25)
+        3) Set audio.timeout to the amount of time to wait before we consider
+           your voice stream as "done".
+        4) Set audio.bitrate to the desired codec2 rate (CODEC2_3200, CODEC2_2400, CODEC2_1600, CODEC2_1400, CODEC2_1300, CODEC2_1200, CODEC2_700, CODEC2_700B)
+
+    KNOWN PROBLEMS
+        * Until the module is initilized by the startup sequence, the amp_pin pin is in a floating
+          state. This may produce a bit of "noise".
+        * Will not work on NRF and the Linux device targets.
