[music-dsp] Re: LP Noise

OK,
create crackle by adding short noise bursts (e.g. gaussian noise, quite low
energy) with different energy and time extent. You might want to LP filter
the noise before adding it to the signal as well. If you add it with
repetitively more energy in equal time distances you can simulate the
33/45/78 rpm recordings if you wish.

The clicks sound quite natural if you simply add a triangle-like noise burst
with higher amplitudes than the crackle but not so often as the crackle. If
you wish, you might want to add an small attack time on the triangle to make
it sound even more natural. Use the same frequency for higher amplitude
clicks as for the crackle to simulate different rpm for the LP.

Thanks for replying.

Actually I wanna make an effector simulating  LP Noise.
I'd like to use no sample if I can.

Thanks again.
More please.. ^^
