• Amazing ★★★★★
    This app is incredible as everything ApeSoft is. However I am very conflicted by the fact that I found this listed as AUv3, particularly stating some multi-instancing improvements on one of the most recent updates. I cannot find it on any of my apps as an AUv3, and unfortunately I’ve left behind the days of using inter app audio or AudioBus audio a while ago. Unfortunately I can’t see myself using this too much unless it gets AUv3 support. Will AUv3 support ever come? Hopefully you can let me know: I find it weird that this is the only app from ApeSoft that I have that does NOT support AUv3. I hope it does soon, as otherwise regardless of how amazing this tool is, it will just deviate me a lot from my workflow which is why I doubt I’ll have much use for it. It does make some crazy amazing sounds though, if you’re not super keen or fixated on AUv3 support this is obviously something you will enjoy (if you know what it does, ofc).

  • 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.

  • Essestial Experimental ★★★★★
    If youre into IDM or experimental then this along with all of apesofts stuff is essential. Sparkle is great for combining textures and patterns in a uinique way. Great with vocal or other files. Sparke goes great with Nave and Scythe for making something new out of vocals or melodies.

  • Truly a phenomenal app ★★★★★
    For sound design this is amazing and unique. If you like creating and experimenting, tinkering around with sounds you can't go wrong with this app. Just like it says " creates high-quality sound transformations. The more you play with this the more you'll see you can do and the more valuable a tool you'll realize it is. Beautiful job they've done on this app.

  • 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.
    By Me knows for Version 1.5
  • Cross Synthesis for the win ★★★★★
    The only Cross Synthesis tool for IOS. Fortunately it was created by ApeSoft, so even if there were ten this is the one you'd buy.

  • Great as always ★★★★★
    It's Apesoft, so you either love it or you don't. App does exactly what's in the description and it sounds wonderful. If you are a fan of mangling sounds to create soundscapes or ethereal grooves, or if you just like exploring sound design, this is a must have. There's a slight learning curve. Tip: the interaction between the Denoise, envelope, and formant movement sliders is where a lot of the juice comes from. Don't ignore those.

  • Sounds can have children ★★★★★
    This excellent app does a great job of being able to combine two sound sources and create a new one which has some of the characteristics of the parent sounds yet its own too. There is a great deal of control and the ability to really dial in your sounds with the controls.

  • Yes! ★★★★★
    This may be my favorite of all the Apesoft apps. I never get tired of what it can do.

  • If you love sound design get this ★★★★★
    It seems to take a source sound and masks it over the destination sound. Its very interesting and I haven't heard anything like it before. It's a really complex machine that will take a while to master.
    By Long words for Version 1.2


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!
