There are a number of sound cards (and have been for 10 years now) that can capture up to 95 KHz with extraordinary fidelity. They sample at 192 KHz and usually have "24" bit converters good tor 20+ bits. These can capture the complete FM MPX output pretty easily.
Some of the newer ADC's have less that .001% THD at 192 KHz sampling. The AK5394a for example has -105 dB THD at 1 KHz. Can be had as a chip for about $22 ea if you want to build your own. Some current motherboards have an SPDIF input that can handle the 192 KHz sample rate. The next challenge is getting the OS to handle it, not difficult.
