We've just updated the [FAQ](https://github.com/deezer/spleeter/wiki/5.-FAQ#why-are-there-no-high-frequencies-in-the-generated-output-files-) for making clearer how you can actually perform separation above 11kHz.

We've just updated the FAQ for making clearer how you can actually perform separation above 11kHz.
Notably we pushed alternate configuration files (spleeter:2stems-16kHz, spleeter:4stems-16kHz and spleeter:5stems-16kHz) that perform separation up to 16kHz and explained how you can set upper separation frequency in the config file if you need another value.

Can we separate up to 22khz, That will be fine
