It is advised to set standard frequencies >= 24KHz to get best quality
except for STM32F10 devices, when the HSE value is 25MHz, it is advised to
set audio frequencies reachable with this HSE value (refer to RM0008 for
more details). ie. it is advised to set 16KHz value in this case.
Note that maximum allowed audio frequency is 96KHz (this limitation is
due to the codec used on the Evaluation board. The STM32 I2S cell allows
to reach 192KHz frequency).
@note
When modifying this value, make sure that the I2S PLL configuration allows
to get minimum error on audio frequency. This configuration is set in file
system_stm32f2xx.c or system_stm32f10x.c.*/
