--- Comment #8 from Carlos Rafael Giani <dv at pseudoterminal.org> ---
With WAV, anything is possible, really. Just look at where WAV can be found
these days. It is used way beyond its originally intended use cases, just like
AVI was before MP4 and MKV became the commonly used container formats for
video. Therefore, it is very difficult to come up with a reasonable value for a
maximum sample rate (or channel count), at least for PCM. So yes, if there's a
PCM WAV file with 1000000 kHz, then we should accept it.

However, other formats inside WAV may have an actual reason for a limit. This
is why I didn't lift it from all of them - I do not know the other formats well
enough for that. I guess the various ADPCM schemes could all have their sample
rate limit lifted, but I just am not sure if this makes sense with them.
