|  Decoder | Audio Decoder  | 
|  Encoder | Audio Encoder  | 
|  ▼Communications | Transmit Audio Please note that the standard Arduino WiFiClient and WifiServer (to use TCP/IP), Serial or BluetoothSerial are also supported.  
  | 
|  FEC | Forward Error Correction  |

|  ▼Metadata | Audio Metadata (Title, Author...)  | 
|  ICY | Icecast/Shoutcast Metadata  | 
|  ID3 | ID3 Metadata  | 
|  Platform | Platform specific implementations. Do not use any of theses classes directly and use the related platform independent typedef instead:  | 
|  Player | Audio Player  | 
|  ▼Tools | Div Tools  | 
|  Buffers | Different Buffer Implementations  | 
|  Collections | Vector, List, Queue, Stack..  | 
|  Converters | Convert Audio You can add a converter as argument to the StreamCopy::copy() or better use is with a ConverterStream  | 
|  Memory Management | Allocators and Memory Manager  | 
|  Strings | Strings This framework is avoiding the use of Arduino Strings, so that we can use it easily also on other platforms!  | 
|  Timers | Platform independent timer API  | 
|  Video | Video playback  |
