Full AudioUnit (AUv3) support

Sparkle is a tool for advanced spectral hybridizations made of several algorithms that operate on frequency domain. By means of envelope preservation and phase-sync processing it can creates high-quality sound transformations.

The basic idea is to transfer the temporal structure of a sound (source) onto another sound (target) of which the spectral properties are preserved.
Simply put, you can take a voice and make it sing a Beethoven’s symphony!

Really nice

Complex. But musical. I have, I think all the apps this individual made and they are all very cool but in my opinion more on the front of making wicked gnarly noise more than music. The ability to feed a drum loop into the one side then putting a pad or sustained sound into the other essentially cutting and gating into rhythmic bits the pad’s sound even to a designated tempo. (Was that even a sentence?) But isn't this achieved with a vocoder or a nice side chain compressor too? This does it differently. (I think) I am SURE I am only skimming the surface here.

This is a nice app that is complex but less complex than some of his other apps. I like it a lot and have spent hours experimenting with just making non-rhythmic sounds hop and skip in time to other more tempo-laden riffs. It’s time well spent!

Thank you for your continued creative tools!
Additionally: I LIKE your GUI’s still and appreciate minimalist GUI's in general. iPad and iPhone apps have, in my opinion, crossed into the “pro” realm awhile back and I appreciate devs who allow me to not have to be on the most current pad or os to use their software and still get big nice sound.

If you like Industrial, Dark Ambient & TripHop, get this

This is Dedalus’s posh uncle. And like Dedalus, make sure you run a limiter after it or your ears will pay the price, it can be unwieldy with levels. For best results, turn off or keep the reverb low, the reverb seems to dull & smear the fourier transforming. If using drumloops make sure you have the bpm’s. Do read the manual because it’s not clear what some parameters do. And make sure to exploit the control menu mapping with midi cc, LFOs etc to all the parameters like Hybridization & Envelope. This app gives you amazing amounts of control. Sparkle also does really amazing & eerie vocoding effects similar to those on “Base Metal” by Download.

Another Great from the Ape

I own all but one app from this company and I've yet to be disappointed. I love sound design and do a good amount of work using modular synths. I rarely ever use the iPad or apps to make music but Ape Soft has some well thought out apps that are truly top notch. The sounds that com out of Sparkle are absolutely stunning in. This is a dream for sound design and experimentation. I dump my own samples into it and toy around and usually come out with more great sounding samples. Amazing.
