Can we use 24bit/192? (AUD-4934)

[vwwwvwww]

I found that the new version of ESP-ADF supports 24-bit audio

and I would like to know if it supports outputting 24-bit/192k (SDCard) audio through I2S ?
and receive & play 24-bit Bluetooth music ?

Another question is, does ESP-ADF only support predefined development boards?

If I want to use a DIY board, are there any examples available?

Refer to https://github.com/espressif/esp-adf/tree/master/examples/get-started/play_mp3_control/components/my_board to define your board.

I think it can be work on 24bit-192kHz from sdcard. And, the A2DP can't support 24bit music, If I remember correctly.

Could you provide a template for using a third-party decoder, similar to the template for "my_board"?

For example, how can I use the following code to decode a WAV file?

                  uint32_t recvSize = 0;
                  do
                  {
                    recvSize =  file.read((void*)buffer, 1024);
                  
                    for(uint32_t i = 0;i<recvSize/2;i++)
                    {
                      partWavData[2*i] = buffer[i];   
                      partWavData[2*i+1] = buffer[i]; 
                    }
                  
                    mi.Write((char*)partWavData, recvSize*2); //i2s_write
                  
                      // startPos += recvSize;
                      // file.seek(startPos);
                  }while(recvSize>0);
                  file.close();
