'array interpolation' abstraction allow us to glide between arrays smoothly. The patch is controlled by a slider, whose values could be changed between 0 and 1. By changing this value, an interpolated version of two arrays is written to a third array.

Have not checked it out yet, but a great idea!

it works great may be if you can interpolate more arrays like 10?
will i did see something like this from the Fairlight CMI 30A i was going to give it a shot -
That's cool mahatGma, I tried using it on an audio array but it I don't think your method can handle bigger arrays, it was very choppy. Plus [expr] is not very mobile friendly
I've been thinking about morphing between sounds a lot recently and your patch gave me an idea of how to do it in the audio domain. Here's a quick patch that morphs between two sounds being played. It works in a similar way to mahatGma's patch with the slider, 0 is the left input only, 1 is right input only. Also added a comparison to simple crossfading so you can see the difference.
It'd be cool to try this out with some different sounds when I get a chance.

really cool! cheers

This actually sounds really shit with other material, seems to be a lot of distortion. Will have to have another look at it.
Does anyone know a good to way to do a difference function in pure vanilla dsp objects?

Hey Jwif, did you check my spectral interpolation patch? It uses interpolated arrays in order to morph the sounds. The 'sounds' consist of frequency and amplitude pairs analyzed by Spear.
@mahatGma said:
This patch allows us to make spectral interpolation between two 'Spear' files;
Using 'Spear'; analyze any length of sound, reduce the content of spectrum by deleting partials below x magnitude{dB} and x length{sec}.

After you've downloaded the spectral interpolation folder
open ~/spectral-interpolator-help.pd
1- type 1 on the number box
2- choose the .txt 'Spear' file {departure}
3- type 2 on the number box
4- choose another .txt 'Spear' file {target}
5- send an init bang
6- start playback [you will hear the first sound character]after this steps you can navigate between two sounds using the yellow slider.
I used Dan Ellis' patch to import Spear file into Pd.

let me share an eleganter version of Array interpolation abstraction
