If I am using Audio sampling freq as 16KHz then Byte rate is 32000 byte per sec. The DMA configuration as (ADC _DMA_UART) mapping using circular mode and Byte for UART and halfword for ADC and baud rate as 460800 will it be ok without data loss... Kindly

UART Bits per sec will be 46080 bytes per sec ... Kindly confirm

Should be straightforward to do a bandwidth calculation.

460800 baud at 10 bits per byte (8 data bits, 0 parity, 1 start bit, 1 stop bits) means you can push 46080 bytes/sec. 32000 bytes/sec is less than that, so it can work.
