I guess I'm biased on this, with one son that did photography and another that is in the film business, I'm sort of inclined to feel that an artist has a 100% right to the derivatives of his/her work, but, hey, that's just me!Yeah... that's just you. Is there really any benefit to the world in keeping stuff like this from being created? Obviously whoever owns the rights to that song could probably get it taken down if they wanted too.
What it does is a FFT for each point in time (each sample) of the song, which gives it a set of frequencies and magnitudes (let's say for example 8khz*10, 5khz * 7.5, 11.5khz at 2.5, etc -- the actual set of frequencies and magnitudes will be a lot more detailed). Then, if you're slowing it down by 90%, what it does is generate 9 new samples in between those other two sounds, by kind of smoothing out the transition between one set of frequencies and the next, much the same way that you can morph two photos into each other.That's what I thought but someone said you have to keep the phase information as well. Although I would imagine that the more 'buckets' you have in your FFT the more precise the sound would be even if you don't keep phase information
paulstretch on OS X.so if anything, the slowed-down version is 16 times as long as the original (or 1600% slower)I was thinking about this. But actually shouldn't it be ((final length - origional length)/(origional length) * 100? Slowed down 100% would imply it was twice as long, and slowed down 0% would mean the same length.
My thought here is that if an artist like Williams (or, for that matter, any other composer, artist, singer, whatever) creates something as moving as the theme to Jurassic Park, does anyone else have the right to bend it and put a "Jurassic Park Theme (1000% Slower)" by birdfeeder is licensed under a Creative Commons License" tag on it?My thought here is whether I have the right to bend this bending of the Jurassic Park Theme 1000% faster* and release it under Creative Commons.
Csound's pvoc will interpolate between frames, but too few frames will generate audible distortion; too many frames will result in a huge analysis file.Your windows (analysis length- how many samples in each transform) also determines the lowest frequency you can reproduce and I think pitch accuracy.
