 # MrDiy Audio Notifier - Schmurtz Edition
  ----
   MrDiy Audio Notifier is an audio player controlled by MQTT.
+
+  It is able to :
+- play local TTS (samvoice)
+- play Google Translate TTS
+- play MP3, AAC and FLAC
+- play RTTTL (Nokia ringtones)
+- play some web radio

+MrDiy Audio Notifier is based on esp8266audio library. This repo uses most of the MrDiy's code with some modifications :
 
 - Ported to platformio (with differents recommanded settings for ESP8266audio)
 - Can be compiled for ESP8266 and ESP32
 - IotWebConf updated to version v3.x (thanks to Markvader)
 - Google Translate TTS (multilingual and better voice quality than the local ESP8266SAM). [List of supported languages](https://github.com/florabtw/google-translate-tts/blob/master/src/voices.js).
-- ability to play AAC (required for many web radio) and flac (not tested)
+- Set voice style of samvoice
+- Ability to play AAC (required for many web radio) and flac (not tested)
 - New settings in web interface allow to switch easily between no DAC (version used by mr DIY) , external DAC or internal DAC (for ESP32).
+- Set volume with physical buttons
 - Documentation to connect your ESP to a speaker (see comments at the top of the "main.cpp" file)
 - You’ll also find some useful comments for wiring your DAC quickly or to improve the code (sound level of RTTTS, ssl, IotWebConf migration to v3.x...).
