You can calibrate the clock on the ADC. One way is to feed a known reference frequency in on the other channel. (That's assuming you have a stereo setup and don't need the second channel for something else.) Another way is to compare the sample rate with the PC clock. That will correct for any long term drift but may not track shorter transients. -- These are my opinions.
