Using audio clock (22.5792MHz or 24.576MHz) as STM system clock

I've seen STM audio boards (SD card player) with only two audio clocks (22.5792MHz & 24.576MHz) on the pcb. Depending on the speed family of the audio file being read, the STM uC is using the relevant audio clock as its system clock. Does anyone have a link to the code which does this, please?
