Questions regarding 44.1 vs 48 sample rates. #487
-
|
I am feeding an ADAU1401 with the required 48 khz sample rate, however my phone shows a SBC connection at 44.1. Is there a mechanism handling sampling rate conversion? Or is it sending empty/duplicate frames? Additionally, for some reason I could not get the default pins to work on a esp32-wroom-32. I eventually found an example that suggested an alternative. http://www.winko-erades.nl/using-an-esp32-and-pcm5102-as-a-bluetooth-audio-receiver/ Thanx. |

I suggest to have a look at my audio tools project that is mentioned in the readme.
I guess some of your pins must be damaged: you can use any gpio output pins! |

TY...I'll do that. Filtering on analog inputs of adau1401 are working as expected, but i2s is being really weird. |

In this case you could also use the analog output of the ESP32 instead of I2S |

There you can easily upsample the output, but please note that the default pins used by the audio tools are different.
Further information can be found in the Wiki in the chapters
