It's unusual to have audio data on UART, but regardless, it's just data as any other. So simply receive data from UART3 to a buffer in memory and then transmit to UART2. Use two buffers, swapped alternatively between receiving and transmitting for continuous transfer.

How is the data actually presenting itself?

Are you using some standard protocol for data transfer across serial or network connections?

Something that's inherently packetize like MP3?​

Why is this more than a buffering and data shovelling exercise in the simplest case?​

How are you failing at it currently?​
