Vio Updated with Audiobus

Vio, the unique Universal vocoder, has been updated with Audiobus support!

Check out the video below to see it acting as an Audiobus Effect for Figure.
Correction: I misinterpreted what was going on here. Vio is only usable as an Input in Audiobus. I'm sorry, this is entirely my fault and not a misrepresentation by Vio or Jazari. In my defense it is pretty fucking stupid to release a vocoder without allowing it to be used as an Audiobus effect; far too stupid for me to have imagined it when I watched the video.

What's new in Vio v1.2.0:

  • adds support for Audiobus
  • adds support for landscape view on iPad (in iOS Settings > Vio)
  • brightened star, share and record icons on the main screen
  • advanced settings are now visible by default
  • adds ability to log out of Dropbox account (in iOS Settings > Vio)
  • performance and stability improvements

Buy Vio on iTunes: $2.99

Jazari is best known for his collection or robotic contraptions, but in this video he's on his iPhone with Vio, Figure, and AudioBus!

Hm.. I can only get it to show up as an input in audiobus, nothing in the effects slot?

Hrmmm... Looking into this now!


I'm the "pretty fucking stupid" guy who wrote the signal processing code in Vio and performs in the video above. Allow me to offer some insight into why we made this "pretty fucking stupid" decision. Vio is not just a vocoder. It also performs pitch-detection and correction--monophonic pitch-detection. If Vio were available as an effect in Audiobus, a user could send it polyphonic input and confuse the pitch detector. The result might sound really cool, or it might sound like garbage. In the latter case, we'd likely have a user who concludes that Vio is broken or fraudulent because it won't properly vocode their piano piece. As a developer, you see this sort of thing all time, and you do what you can to avoid it. We're working on ways we can implement Vio as an Audiobus effect in such a way that it doesn't leave users confused or disappointed. This is non-trivial and takes some time.

What does take a trivial amount of time is emailing a developer to inquire about their product before launching into a profanity-laced tirade. Failure to do so is what I would call "pretty fucking lazy" journalism.

Yeah Tim that's some pretty bad form there. I've followed this blog for quite a long time now and I appreciate your frank tone but sometimes you're too quick to trash an app or developer.

Ooooh burn!

May 02, 2013  | person_outline Zymos

That's totally fair, Asgard, and you're probably right.

However, in this case I was pretty displeased with the realization that a vocoder with Audiobus, cannot be used as a vocoder in Audiobus. Especially when that vocoder does not clearly indicate that in their iTunes description page. Typically apps with limited Audiobus support are clear in their iTunes page about the specific limitations of how it can be used. After I pointed this out them they amended it to avoid any further confusion, but this was after 3-4 hours in which this post was on the site which could have mislead readers into spending $3 on an app that can't do what I said it could.

Betraying your trust by misrepresenting an app's functionality is about the only thing I can really get wrong in my role here.

While I take full credit for the fault here, and was clear in absolving both Vio and Jazari of any blame, I do not think that my mistake was an unreasonable one. I believe sincerely that it is pretty fucking stupid to release a vocoder with Audiobus support that can not be used as a vocoder in Audiobus.

To Patrick's point: There wasn't time to contact you after I realized my mistake. I needed to issue an immediate correction. I do like to reach out to developers when I have the time, but frankly I didn't have it because in the middle of running this site I'm working 2 other jobs.

You know what would be pretty fucking sweet? If you could run Garageband as an input into Vio as an effect in Audiobus.

It sounds like the latter is being worked on. Pretty fucking awesome.

And I propose, the only adverb to be allowed the rest of the day: pretty fucking. A term which, by itself, takes on a whole other meaning!

Vio got its pretty fucking homage and a pretty fucking word of mouth. Move on Pat, you got your publicity right there.

BTW, Kymatica's bitwiz sounds like garbage, actually like a trash compactor when used as filter mode, actually, not very different than when used at all, still... some people like the unique trashy sounds, pretty fucking trashy sounds.

Re: Vio
They have been pretty open and honest about the app only working in the Input slot. On another blog or site I saw a post from them explaining why it isn't designed for the FX slot.

Re: Vio not working in FX slot
I get the impression that it is difficult to modify your app to work in the FX slot. The majority of AudioBus supported apps are only for the Input slot. Then a few more support the Output slot as well. Then there are the small number who also support the FX slot. Anyone know why this is? Difficult to program for FX slot?

Re: Vio tip
One of the Vio guys posted a tip for using Vio. He said that when you move your finger across the screen, if you leave it in one place for a while 'the algorithm has time to calculate and generate the audio effect', or something like that. The bottom line is you get one effect if you keep moving your finger, but you get another if you leave your finger in one place and allow time for the app to generate the effect.

I agree 100% Patrick.

But let me ask a question: is Tim a journalist?

I am a big fan of Tim and dsicchord, but I know it is not The New York Times, The Times (London), or The Sydney Morning Herald.

It is more of an opinion piece by a iOS music hobbyist. Tim is one of us. That's why we love him.

So should we expect the standards of journalism we get from established news outlets? Do bloggers also have a duty to make sure their facts are correct? Or is reading a blog more akin to listening to some bloke shoot his mouth off at the pub?

You are not stupid. It is almost impossible not to think it is obvious that audiobus effect slot is a must for this app. Of course i am not buying until this happens

May 02, 2013  | person_outline Mike

I've noticed people only call me a journalist when they are angry with me.

It might be desirable, but it is not 'a must'.

The app has been sold and used successfully in a version that didn't even have AudioBus.

Now it has AudioBus you can send the audio to an FX app or recording app - even better!

If the developers can work out a way to use the app in the FX slot then great - we'd all love that. But if they can't implement that feature it will still be a fantastic app.

Don't let the lack of "FX slot use" stop you from buying this app - it is very cool.

Tim,i like your way of discussing apps,& if some people think your to quick to trash apps so fucking what,I find it refreshing whether your right or wrong.It says something about your website when its the only one i know where a question or opinion on a app will be said & almost straight away your get the developer write a reply.I nearly wrote how shit Turnado was on ipad 2 until i went onto your site & their were so many comments on how great it is for other ios users,all i get is terrible cracking,clipping cant play a song into it,need to see video on why people like it,because every video ive seen on it so far make it look like some awful uncontrollable techno,i bet that comment brings me shit!

Let me second you, Simon. I found this update pretty fucking cool and the App in itself sounds pretty fucking good, IMPFO.

May 03, 2013  | person_outline Suggathang

The attached video does make it look like Vio is processing audio from Figure. I realise the video isn't official.

I like Vio, but I love Turnado, which is a truly awesome professional multi-effect app.

Yes, Turnado is amazing.

But they are 2 different apps, designed to do 2 different things (and Turnado is a $20 app and Vio is $3).

Vio via Audiobus into Turnado = wild!

May 03, 2013  | person_outline Simon

i for one bought it assuming (not because of this video) that it would work in the effects slot. still pretty cool, though. hopefully polyphonic pitch detection will come soon and they'll update it for the effects slot.

If you're worried about user error making crap sounds why not throw up a message when you detect the app is used as FX? 'WARNING: This app is designed for monophonic input. For best results use only single note playing as input'

May 03, 2013  | person_outline RMG

You know what's "pretty fuckin stupid" that impc app grrrrr get'em Tim :)

May 03, 2013  | person_outline Mr. Wonderful

Meh. Not really tempted by the app.

May 03, 2013  | person_outline Ism

This is a really cool app. Even better through AB.
