I'm wondering how to implement scratch effect in Csound
or similar vinyl effects. Has anyone done this? Cheers, Anton |

A cheap way would be to record the audio output of no-audio signal from a real vinyl player and convolve it in csound? I imagine the complexity of the noise coming from real vinyl is too high for a brown/pink/gray noise to imitate, so sampling the noise would seem to be the best way to go. I've only used this effect from VST plugins and I imagine they use samples in the background.2015-09-14 19:11 GMT+02:00 Anton Kholomiov <anton.kholomiov@gmail.com>:

ahh sorry I misunderstood the question, scratch effects, I'd like to know about it too actually, negative playback speed on lsocil with noise? Well, I look forward for some implementation if one exists. 2015-09-14 19:24 GMT+02:00 Hlöðver Sigurðsson <hlolli@gmail.com>:

Try to experiment with diskin2 speed parameter. Including negative values of course. 14.09.2015 20:12 пользователь "Anton Kholomiov" <anton.kholomiov@gmail.com> написал:

I wonder for realtime performance, to record last 10 seconds of audio output into buffer, garbage collect old samples for new ones (10 second table size), and have the buffer listen to midi coming from midi "vinyl" disk, to scratch back. If that recording mechanism will slow it down too much. But it would be a cool concept, because most of the time (for me at least) csound users are not using pre-recorded samples. 2015-09-14 19:33 GMT+02:00 Gleb Rogozinsky <gleb.rogozinsky@gmail.com>:

It's straightforward to do this with tables. There is FLTK example in the csound sources using a granulator to do this scratching, I think it is called timescaler.csd. Victor Lazzarini Dean of Arts, Celtic Studies, and Philosophy Maynooth University Ireland
