If there are tens of thousands of silent samples, due to errors, then
you might hear silence. However, it's more likely to be short enough
to sound like a glitch. In fact, fewer erroneous samples will sound
more like loud distortion than silence, depending upon the difference
between the missing sample and zero. This is all assuming individual
samples.
What's more likely is that a given error will destroy everything from
the current sample to the end of the block. That's mostly why the
documentation mentions silent sections. If you have a bad FLAC file
and use -F, you'll probably end up with silent blocks. The default
block size for a FLAC file is very similar to the block size of a CD,
so glitches might sound roughly the same. One difference is that
many CD players have digital filters which chirp when there is bad
data, while a FLAC will not have this same sound effect when errors
are detected.

is this above correct or are there more situations that can occur in
the case of corrupted flac files you want to decode using -F?
