- 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

enable audio filtering before queueing it to player component
fix low volume due to wrong init of audioDAC_data add support for mixing stereo to mono through dsp_processor (fixes #106) add sdkconfigs to github action workflow suppress warnings from flac git submodule remove unused variable and address some compiler warnings remove some dead code Signed-off-by: Karl Osterseher <karl_osterseher@gmx.at>

mix stereo audio (left and right channel) to mono and play it on the left AND the right channel
add support for sample rates different to 48kHz (#15) - instead of storing chunk duration in ms store the frame count and do calculations based on that - add updated snapserver.conf for reference (#17) - some code clean up - move Kconfig entries to correct place - remove unnecessary Kconfig entries - add necessary dependencies in Kconfig files Signed-off-by: Karl Osterseher <karli_o@gmx.at>

reduce RAM footprint of dsp processor and add a simple EQ (bass, treble) to dsp processor dsp processor now will process smaller chunks of audio at a time and loop over the audio data array which results in a much smaller RAM usage but probably longer execution times of IIR filters.
