Can we use 24bit/192? #367
-
By using ESP32 or STM32, I'm interested in building a 24/192 audio effects device. I know this library can be used with ESP32, but I am not sure about audio resolution. |

I don't really have any experience with this: With I2S, I am usually using 16.bits and never go over 44100hz. I would expect that you might run into calculation perfmance issues at that speed: Int16 operations are fast but int32 and floating point operations get much slower! The ESP32 might be on par (or slightly faster) with an STM32F4 (e.g.Black Pill). |

I guess because you forgot to install the related codec library |

But up to 32 bits are supported and if you use Google you can find that the maximum stable sample frequency appears to be 1.3 MHz.

I am wondering how it compares with a STM32F7...
