Internet Broadcasters! Broadcasting from your iOS device could be just around the corner!

A lot of us Blind folks are interested in radio. Some of the lucky ones are probably doing an air shift in a commercial station as I write this. :) The rest of us, may be doing that one of these days, but for the time being, we get our thrill by broadcasting on the internet.

Today, when we think of hosting a show, we think of needing a desktop, or laptop computer. This all may be changing, very soon!

How cool would it be to broadcast an internet radio show, from wherever you are?

It seams a lot of us have iOS devices, and the future of hosting a show from our IPhone or IPad is litterly right around the corner.

Their are several apps I want to cover here.
First, because it's kind of what makes all this come together, let’s talk about Audiobus. (You can find a demo up at the Applevis podcast section).

Audiobus, allows for live app to app audio streaming. It's quite accessible, and allows you to connect your apps together. Apps can either be an audiobus input, an Audiobus fx (between the input and output), or an audiobus output. You can have multiple inputs, (multiple apps playing audio at once), that live stream to an Audiobus app that acts as an output, (reseiving the audio).

One advantage as Voiceover users that we gain when using Audiobus, is not having Voiceovers speech travel through the Audiobus pipeline. So we can still be gaining VO feedback, but no one else has to even know VO is enabled.

Each day more apps are updated with Audiobus support, Now, let’s dive into where internet radio broadcasting comes into play!

At the time of writing this post, two of the apps that I will mention here are in Beta with Audiobus support. Bossjock Studio is currently in the app store, and a lot of us use it on a day to day, (Current beta includes Audiobus in and output support). KoalaSAN Broadcaster is probably a new one to a lot of us. KoalaSAN is not yet in the app store, and is completely in its beta stage at the time of this writing.

Bossjock studio: allows for numerous carts, which can be loaded from your iOS devices music library, dropbox, etc. Bossjock also includes a mic button. All audio goes through AGC processing, (compression and limiting). You can export to various file formats and export via mail, dropbox, ftp, etc. Its main mission was and is podcasting with no post processing/editing needed! and it does a heck of a job!
Carts=doubletap and play, play multiple carts at a time. (I'm sure you can see how that process could transfer over into manually cross fading of music like dj's of the 90's with CD decks.

Djay: a DJ style application for the IPhone allowing for automatic cross fading/(auto mix) auto volume leveling etc. Djay pulls from your iOS IPod library, with no need for conversion to another file format, taking up less space on your device, and less time because no reencoding is needed. (latest update brings Audiobus in support).

KoalaSAN, (still in beta not in app store at the time of writing), A shoutcast/icecast source, (you input server information into KoalaSAN, and it will stream to server of choice). either from the iOS devices microphone or acting as an Audiobus output. Mp3 and Ogg formats are supported. Also dumps, archives the stream and allows for uploading of recordings to ones dropbox account.

I'm sure your mind is already putting all of this together. Connect any app that acts as an Audiobus input, through Audiobus to an Audiobus output, and you get that audio in the Output app, no matter weather it's recording the audio, or Shout/Icecasting that audio out to a server, live, in real-time! But lets shift away from music players for a moment. What if you want to pre-record, or host a live concert, with an instrument app, That is as well possible.

To sum it all up, theirs a lot of cool technology right here! and right around the corner! It's way to cool, and trippy, that we will all be able to host our internet radio shows right from the eas and comfort of our IDevice from any location!

#1 Wow...

It is simply amazing what all is possible, and what will be possible sooner than we think. While this post is about internet broadcasting, it makes me wonder of the possibilities of such a set up for live musical performances. I have considered using an iOS device in a show, but didn't want the audience to be subjected to Voice Over. This article suggests that this sort of set up is now possible. I'm going to check into that.

#2 How to separate voiceover audio and iOS audio with simple trick

App Developer

When I'm demoing BlindSquare to live audience, I would love to use AirPlay to send my iPhone screen + audio to video projector/speaker, for example using AppleTV. It is working ok, but VoiceOver audio is not sent via AirPlay. I saw this as a problem (and I'm using lightning->VGA convertor + bluetooth audio streaming instead), but this can be used right away to separate VoiceOver-audio and iOS audio. I just tested that it works. In my test I run AirServer on my MacBook (http://www.airserver.com/) -- With this app my laptop can RECEIVE AirPlay connections. In my iPhone5 I connect my audio via AirPlay to my MacBook. Result: All iOS audio can be heard from MacBook, but VoiceOver stays on iPhone.

#3 ...works with AppleTV too

App Developer

I just made another test: When streaming to AppleTV, the same thing happens: VoiceOver is not played via AppleTV --> You can use AppleTV to outpiut iOS audio without voiceover.

#4 Maybe, maybe Not

Hello, thank you for reading and contributing to this article. Really any type of stream, is going to have latency issues. Basicly, Latency, is the time it takes from you performing the action, to the time it gets to your listeners. When I mentioned a live instrument situation within the article, I was refering to you being in one place, and your listeners tuning in while in another How could this work? If you and the listeners are in the same place, and your only using your iOS device, and your solo, and backing tracks are going through the same iOS device to Audiobus out to KoalaSAN, this would work. (Note, this wouldn't work if you were singing to these tracks). What you play, is going to take 2-3 seconds to get out past the server to your audience. How wouldn't this work: If you have a backing band, and want to use your iOS device to play an instrument to solo, or, play in time with the rest of the band. Thanks again for your contributions. All the best, Drew

#5 Amazing. so in theory I could

Amazing. so in theory I could if and when it comes out plug in a line in source in to the lightning adapter of my ios device, run boss joc which hasa mic button and if papaya is ever supported use it to stream to in conjuction with audio buss to a shoutcast/icecast servir. I woudl need to find a way to toggle the phone's mic sepratly though to I don't ' get problems. All of this is of corse in theory. as nothign exists for hardware for the iphone 5. Take care.

#6 Instructional Podcasts&Tactile Diagrams

I agree! The potential for iDevices in these areas is being realized very quickly now. All of the early adaptor/genius types out there are doing a great job figuring it all out and giving us helpful podcasts. Then, there are the people like me, who have a hard time figuring this stuff out. But, once we get it, we get it. I resolved my confusion, and increased my proficiency, by getting some folks involved in creation of the iPhone/iPad Tatile ScreenShot books. They helped me get pictures of the screens into my head so I could go a lot faster. So, I'm wondering how many of these apps are starting to be used by kids/adults in various educational settings and whether a demand could be created for diagram books to help people understand the screens, in ImproVox, for example. Of course, the other thing would be to get the developers on board in terms of VoiceOver accessibility to make the whole thing maximally user friendly. Anyway, the folks at Tactile Vision are asking me to come up with more book ideas, and it strikes me that Internet broadcasting and music production on iDevices would really be great areas to focus on. We become very "mainstream" if we can do this kind of stuff. Anyway, just throwing it out there to see what people think.
