Adafuit / UDA1334A Rout and Lout #458
-
Would it be possible to connect the Rout and Lout from a UDA1334A to the esp32 and use that as a source for sound data? |

You would need a proper audio adc. I suggest you have a look at the external adc and audio board wikis of https://github.com/pschatzmann/arduino-audio-tools/wiki |

I suggest to look again. All devices/modules that have a 3.5mm or RCA audio input should potentially work. |

Yes, you need the proper hardware to input audio in stereo with a good quality |

I think, no: You would need to use the AnalogAudioStream (of the AudioTools) which uses the esp32 ADC via the I2S DMA API to get the necessary sample rate. However it supports only mono. Or you can use the IDF I2S API directlyy. But expect quite some noise... |

https://github.com/pschatzmann/arduino-audio-tools/tree/main/examples/examples-basic-api/base-adc-a2dp might be a good starting point |
