+# py_aax_decode
+
+**py_aax_decode** is a python script which decodes Audible AAX files into
+PCM WAV format.
+
+This script *requires* a functioning installation of Audible Manager for
+Windows, capable of playing back the AAX file in question. The script
+simply calls functions in  ```AAXSDKWin.dll``` to decode the AAX file,
+and then writes the resulting audio data to disk.
+
+
+## Installation
+
+* Install Audible Manager and sign in to your account.
+* Run the script: 
+```cmd
+python3 -c "from py_aax_decode import main; main('c:\\path\\to\\input.aax', 'c:\\path\\to\\output.wav')"
+```
+* If you're not on 64-bit Windows or have Audible in a non-default location,
+you will need to provide the path to AAXSDKWin.dll:
+```cmd
+python3 -c "from py_aax_decode import main; main('c:\\path\\to\\input.aax', 'c:\\path\\to\\output.wav', dll_path='C:\\Program Files\\Audible\\Bin\\AAXSDKWin.dll')"
+```
