Hello,

Is it possible to modify existing source by timeout? 

For example:
s = single(...)

def modify_source(s)
    s2 = single(...)
    add(normalize=false, [ sequence([ blank(duration=5.), fade.initial(duration=5.,s2) ]), fade.final(duration=5.,s) ])
end

s = apply_func_by_timeout(func = modify_source, timeout = 1., s)
output.dummy(s)

Kind regards,
Alexander.
