Oh, please don't change the name.
yours's one good tape machine.
i just wanted to practice and try to make another version work, maybe different but work.
hahahahha. thanks.
I'll work on the fixes soon.

Thank you guys for trying my little toy out. here comes verysion 0.4 alpha for more testing pleasure.
I've adjust a little bit, try to make it more simple..
and the result is surprisingly better.

It's not quite as good as the previous two of yours, IMHO, but it's still pretty good. I'm starting to think that this whole grains thing can easily be overdone. The mind needs something to grasp on, little fragments of voice or sound are necessary. If we chop it up too much it becomes unintelligible, which may be your desired effect, but usually not.

Hahahha i really like the old versions' result.. but one thing they produce are too much digital noises resulting in very high frequency noise. When I said 'better' here is that the copied signal looks more like a smooth sine wave. I intended to use the raw sine wave as the starting point because i want to test if it produce too much aliasing or noisy overtones out of original sine wave.

one thing the examples sounds very different because I change it all the time to test and see if there are still so much noise or not. when I'm satisfied, i posted the code hehehheh.

i'll implement more toys for it now ^_^. thank you guys.

I tried to fix LiSa in Synth Lab to make a recording similar to what you two are doing, and it went "sproing" like a jack-in-the-box! I coded that thing way wrong and now it's totally broken, so it's back to the drawing board for me. Shrug, it happens! Keep on ChucKin'...

Hi!

I am sorry if this is not the right place to post this, but it looks like the topic is kinda similar.

I recently started using ChucK. I am very interested in live electronics and really want to keep using it as I really enjoy its approach. I have almost built all the pieces I need for a new work I want to write, but I feel very puzzled about real-time pitch shifting. The already built-in pitch shifter (I think it uses the delay approach) does not sound that well to me and I would like to try making a granular one.

My question is: Is it possible to use LiSa for real-time pitch shifting?

As LiSa is sample-based, the only thing I could think of is getting an extremely short buffer, process it, and play it; and repeat this for the whole thing, lots of very short sporks.

I hope this is clear enough. Thank you for reading!
