How to get list of time marks for silence?

Hello,

could someone advise please if there exists a fast way to get a list of time 
labels for all periods of silence in an audio file? 

I can get such list in a "long way" with a command:

play someFile.mp3 silence -l 0 1 0.26t -54d : restart

And wait till the whole file will be played at normal speed to get the
needed information:

In:0.04% 00:00:00.74 [00:29:29.08] Out:14.5k [      |      ]        Clip:0
In:0.88% 00:00:15.60 [00:29:14.22] Out:341k  [      |      ]        Clip:0
In:0.90% 00:00:15.98 [00:29:13.84] Out:349k  [      |      ]        Clip:0
In:0.92% 00:00:16.35 [00:29:13.47] Out:356k  [      |      ]        Clip:0
In:0.94% 00:00:16.72 [00:29:13.10] Out:363k  [      |      ]        Clip:0
In:0.97% 00:00:17.09 [00:29:12.73] Out:369k  [      |      ]        Clip:0
In:1.03% 00:00:18.20 [00:29:11.62] Out:400k  [      |      ]        Clip:0

Is there some way to get this sort of information fast? (I tried to
look into 'stat' effect, but could not figure out how to use it for
this task.)

Thanks.
