iVoxel is not only an amazingly sounding vocoder - the unique concept of iVoxel turns this vocoder into a singing machine. iVoxel is a combination of a voice optimized synthesizer and a vocoder. The vocoder part is based on the Matrix vocoder from VirSyn used by many famous artists - one of them the well known german group Kraftwerk. The channel filters used by iVoxel are based on the Sennheiser Vocoder VSM201 resulting in a rich and fat analogue sound characteristic.

The pitch follower and automatic tuning let you sing correct to a selectable scale.

You can use iVoxel in many different ways:

As a realtime vocoder talking into the microphone while playing tunes on the keyboard. The sound character of your voice can be changed in many different aspects like pitch, gender or breath noise. Use it to sing over your favorite iTunes song !

Record the analyzed spectrum of phrases and words from your own voice. Then use this voxel to play with your own voice on the keyboard or with the build in sequencer. Nearly 300 hundred prerecorded voxels are already included.

iVoxel is Audiobus compatible and can be used in the Input, Filter and Output slots in the Audiobus signal chain. The carrier signal and the vocal signal can now be fed by any Audiobus compatible Apps.

The output of your creations can be recorded to an audio file which you
can use with other Apps and programs for further processing.

Well I am stoked - it's back!

I has been reading the reviews and saw how this great vocoder, possibly the best on iOS, just eroded away to the point where it didn't even work. Combined with how far back the last update was, I didn't take any chances and just waited. Patiently.

And I knew it would happen! Well, I hoped anyway, that eventually an update would come out of nowhere and it would be back in business. So I downloaded (on sale to boot!) and it's everything I hoped it was. I see now why it was the go to choice in so many demos a year or so back. My only quip is that I've had a few times where it just stops playing audio, not sure why, and only when sampling the demo sounds/settings. That, combined with the sequencer either not working correctly or there not being good "help you get started" help contextually available... Makes it hard to give it 5 stars. A solid 4? For sure.

Thanks to their team for bringing this back to life, I am super stoked and it's worth every penny! It was the missing piece I've been needing to fill for quite a while now. Nothing else out there fit the bill, at least not on this platform or anywhere near this price. Again, thank you!

Wow why is this 3 stars?

This is such a great app!

Jakob Haq just released a video on vocoders and in all honesty given that the app was on sale I decided to get it as he featured it A LOT. I was quite interested as I HATE inter-app audio and although Jakob isn’t as uptight about this as I am, if he was using an inter-app app, he probably had a reason.

This app is a beast! Please fix it’s few issues (import button for example) and make this AUV3. If would be a FANTASTIC AU.

👌🏼 worth it, regardless!

Outdated and Almost Broken

There’s very little I can say that’s good about this. Want help with this app? Too bad. Look it up.

Want to export something? Feel free to click help on all 9 tabs. Maybe you’ll figure it out, but if not: thanks for the $7.

Now I’m off to buy a better app or a better alternative. What a waste of time.
