How can I count I2S MCLK ticks?

I'm designing a USB audio interface which uses an isochronous feedback endpoint to tell the host machine the required number of audio frames per USB frame. In order to calculate this value I'd like to count the number of I2S MCLK ticks which have occurred since the last USB frame.


How can I do this please? If it's not possible, is there an alternative way of calculating the USB feedback value?
