- merge with original master from jorgen - minimize RAM usage of all components - use both IRAM and DRAM in player component so we can buffer up to 1s on modules without SPI RAM - support fragemented pcm chunks so we can use all available RAM if there isn't a big enough block available but still enough HEAP - reinclude all components from jorgen's master branch - add custom i2s driver to get a precise timing of initial sync - change wrong usage of esp_timer for latency measurement of snapcast protocol - add player component 2021-08-19 21:57:16 +02:00			`# Config file for ESP32 DSP Processor`

- add sdkconfig for NO_SPIRAM and SPIRAM situation - detect snapcast configuration and init everything accordingly, e.g sample rate, chunk duration, ... o calculate apll predefines in dependence of sample rate o communicate these settings to interested parties - remove typos 2021-08-26 22:08:17 +02:00			`menu "ESP32 audio buffer and I2S config"`
