STM32F4 discovery GPIO remapping

Hi everyone from London in the UK.
My name is Steve. I have an STM32 F4 discovery board and am attempting to get I2S and the audio codec working for the STM32Duino project. The project is the brainchild of Roger Clark from Melbourne and gives Arduino IDE capability to the discovery board. I am trying to get I2S working and am wracking my brains on how to remap SPI3 to the pins for the I2S. I have been looking at the reference manual and in particular the GPIO alternate function registers. I need some help in understanding how I would remap the SPI 3 to the I2S pins using bare metal code. Could someone please help me with this?
