We also provide plenty of examples that demonstrate how to implement the different scenarios. The __design philosophy__ is based on the Arduino conventions: we use the ```begin()``` and ```end()``` methods to start and stop the processing and we propagate the __use of Streams__. We all know the [Arduino Streams](https://pschatzmann.github.io/arduino-audio-tools/html/class_stream.html): We usually use them to write out print messages and sometimes we use them to read the output from Serial devices. The same thing applies to “Audio Streams”: You can read audio data from “Audio Sources” and you write them to “Audio Sinks”.
- A Timer based Source - [TimerCallbackAudioStream](https://pschatzmann.github.io/arduino-audio-tools/html/classaudio__tools_1_1_timer_callback_audio_stream.html)
- Analog output e.g. with an Amplifier – [AnalogAudioStream](https://pschatzmann.github.io/arduino-audio-tools/html/classaudio__tools_1_1_analog_audio_stream.html)
- with a Piezo Electric Element – [PWMAudioStream](https://pschatzmann.github.io/arduino-audio-tools/html/classaudio__tools_1_1_p_w_m_audio_stream_base.html)
- Encoding and Decoding of Audio [EncodedAudioStream](https://pschatzmann.github.io/arduino-audio-tools/html/classaudio__tools_1_1_encoded_audio_stream.html)
- A Timer based Sink - [TimerCallbackAudioStream](https://pschatzmann.github.io/arduino-audio-tools/html/classaudio__tools_1_1_timer_callback_audio_stream.html)
- Callback integration e.g. with ESP8266Audio [AudioOutputWithCallback](https://pschatzmann.github.io/arduino-audio-tools/html/classaudio__tools_1_1_audio_output_with_callback.html)
Each stream has it's own configuration object that should be passed to the begin method. The defaultConfig() method is providing a default proposal which will usually "just work". Please consult
the class documentation for the available configuration parameters. You can also easily adapt any provided examples: If you e.g. replace the I2SStream with the AnalogAudioStream class, you will get analog instead of digital output.
Further examples can be found in the [Wiki](https://github.com/pschatzmann/arduino-audio-tools/wiki/Examples). The library also provides a versatile [AudioPlayer](https://github.com/pschatzmann/arduino-audio-tools/wiki/The-Audio-Player-Class).
The application uses a built in logger (see AudioLogger.h and AudioConfig.h). You can e.g. deactivate the logging by changing USE_AUDIO_LOGGING to false in the AudioConfig.h:
Per default we use the log level warning and the logging output is going to Serial. You can also change this in your sketch by calling AudioLogger begin with the output stream and the log level e.g:

You can download the library as zip and call include Library -> zip library. Or you can git clone this project into the Arduino libraries folder e.g. with
If you want to use the library in PlatformIO, you can find a [detailed description in the Wiki](https://github.com/pschatzmann/arduino-audio-tools/wiki/Working-with-PlatformIO).
