Pitch shifter

Hi,

I'm trying to build a pitch shifter using delay lines and a lookup table that holds a triangular window function for gating.

The problem is I'm not sure how to implement a lookup table in Reaktor. I'm guessing I'd need to use the event table module?

At the moment I'm using two delays one half of a buffer-length apart, but I want to crossfade back and forth between them using the lookup table to prevent the click as the buffer record & play points meet.

Thanks for any advice.

I think in this case you would need to use an audio table, since your crossfade needs to work at audio rate ?

not sure what you are doing, have you had a look at clists ginsu grain player ? maybe this is helpful for you

 

I'll have a look at the ginsu grain player, is it in the user library?

I did mean an audio table, I was confused!

Thanks

 

have a look at Live Sampler by Stephen Wierenga in the user library.

after the sampling section is a pitch shifting effect. for me it is a "classic" NI pitch shifting device that was in the reaktor 2 and 3 library, but is not longer included in the purchased library.

it really is worth looking at (and so is the sampling bit)

I made a screenshot of it's structure, maybe this is helping you
I didnt have a close look myself yet, but it seems quite efficient and interesting - thanks for the hint sowari

 

Thanks sowari and lxint I'm just checking them out now. Looks just like what I wanted to do.
