[SoX-users] returning time of signal onset after silence

[a1s2d3f4 <sch...@gm...>]

I can't figure out how to return in the console window the time value in the
WAV file which silence effect knows when it finds my signal.

for example

sox <input file> <output file> silence -l 1 5 0.5%

remove 15 milliseconds from the beginning file, because that's where the
signal begins.

how do I make this 15 ms value to display in my console window (or better
yet, piped into an output file which I can then read with another program)?

I use Win 8.1

For now I just want to get this to work.
But later I want to further complicate this by checking if the signal has
the frequency of "440Hz", and if not, keep searching forward until this note
is encountered and return the corresponding time value.
