 ### Synchronous Multiroom audio streaming client for [Snapcast](https://github.com/badaix/snapcast) ported to ESP32
 
 ## Feature list
-- Opus and PCM decoding currently supported
-- Wifi setup from menuconfig
+- Opus, FLAC and PCM decoding currently supported
+- Wifi setup from menuconfig or through espressif Android App "SoftAP Prov"
 - Auto connect to snapcast server on network
-- Buffers up to 150 ms on Wroom modules
+- Buffers up to 800ms on Wroom modules
 - Buffers more then enough on Wrover modules
-- Multiroom sync delay controlled from Snapcast server 400ms - 2000ms
+- Multiroom sync delay controlled from Snapcast server (user has to ensure not to set this too high on the server)
 
 ## Description
-I have continued the work from @badaix and @bridadan towards a ESP32 Snapcast
-client. Currently it support basic features like multirum sync, network
-controlled volume and mute. For now it only support Opus and PCM 16bit/48Khz
-audio streams and the synchornization part is still being worked on.

+I dropped the usage of ADF completely but copied stripped down, needed components to this project.
+This was necessary because ADF was using flac in closed source precompiled library

+samples and therefore no precise sync could be achieved.

 will find parts that are only partly related features and still not on the task

 The snapclient functionanlity are implemented in a task included in main - but
 will be refactored to a component in near future.

 Sync concept has been changed start 2021 on this implementation and differ a
 bit from the way original snap clints handle this.
