Hi!
The aim is to generate audiofile with one/few-sample-length impulse inside
silence. Is there suitable software to do the job?
Thanks in advance!

You could use your favorite programming language or a hex editor to
create a file with some number of binary 1s, then some binary 0s in the
desired sample format, then use sox to convert it from raw format to wav
or whatever you need.

If you don't mind some coding you could probably do it in a few lines
using libsndfile.

If you don't like programming, you can do it in Audacity!
Open Audacity and make two tracks. Generate the required length of
silence in one, and a *very* short tone (eg a square wave) in the
other. Zoom in till you can see the individual samples, and
copy-and-paste 1 sample from the square wave into the silence.
Good luck,
James.

Many. Attached is a patch to do this in Pd.
Ciao

I usually use Matlab for this. Octave may also be used. Both of these
are very suitable for that kind of work.
In Octave:
-----------------------------------------
% Make a 100000 sample vector of zeros,
% set sample 50000 to one (the impulse),
% write to file
t = zeros(1,100000);
t(50000) = 1;
ausave('impulse.wav',t,44100,'long');
