[Csnd] Sample of single note oscillator how to align at the edges?

Anton Kholomiov
I've got an audio file with analog synth single note sample. But it's not aligned at the edges and it produce pops when looped. How it can be solved without manual editing of the file?  

So how can I loop over this file? Is it possible?

Hi Anton,

Theoretically you may try the following. You can read your sample into a ftable using GEN01. Then you can scan it to detect the time of the onset of your sound, and the time when it fades to 0. After that you copy it to another table eliminating pauses in the beginning and in the end.

Does it sound like a solution for automatically edit sample?

Thanks Gleb. I think it can solve it. Can discontinuity of derivative cause artifacts?

genell
Discontinuity of dedicate will not cause a 'pop' but will of course add overtones as the waveform will not be 'pure'. 
In fact, the 'pop' is also the addition of an almost unlimited number of overtones to account for the discontinuous waveform.

Anders
