Hyperaudio at the Mozilla Festival
This year has run contrary to previous years of my life in the sense that it seems to have lasted much longer than the year before. This may have something to do with a small addition to the family that arrived in March and the consequent ramping up of waking hours, but I prefer to think it’s because things are moving so quickly in that wonderful place we call the worldwide web, that it seems that too much has happened to compress into a year.
It was only a year ago for example, when I started tinkering with jPlayer to couple text and audio and was asked to show off a very small demo at the first Mozilla Festival in Barcelona last year.
A few months later I was introduced to and became involved with something known as Hyperaudio and was given the opportunity to create a couple of proof-of-concept demos : Denmark Radio’s Hyperdisken Demo and the Radiolab/Soundcloud collaboration ( a shout-out to Henrik Moltke for doing much of the groundwork for these demos and my colleagues at Happyworm without which they just wouldn’t have been possible).
Further on through the arc of this epic year, I took part in the Mozilla Knight Journalism challenge where I was encouraged to research and blog some ideas on a tool I called the Hyperaudio Pad. Happily I was flown over to Berlin with other like minded MoJo peeps, for a week of intense discussion, collaboration and hacking and managed to get the first semblance of an actual product out of the door.
Which brings me in a round-about way to this year’s Mozilla Festival, where I will again be demoing and chatting about the coupling of text and media and the other things that Hyperaudio is (or could be) about. This all at the Science Fair on Friday, 4th of November and a Hyperaudio Workshop / Design Challenge on Saturday, 5th.
The Science Fair will be all about demos, chatting to people interested in the general Hyperaudio concept and making sure I don’t spill my drink over my laptop. Meanwhile in the workshop we hope to put the Hyperaudio Pad through it’s paces and actually make something with it, while gathering ideas and maybe hacking on some of them into the bargain. It should be a fun mix of hacks, hackers, designers, audio buffs and basically anybody curious enough to be involved. The session will be fairly free flow but the plan so far is to:
- Briefly chat about and demo the Hyperaudio concept, what it can do and with whom we can collaborate.
- Breakout into groups to come up with new ideas, applications and designs.
- Reconvene and talk about the group’s ideas.
- Breakout into groups to work on these ideas, whether it is creating a programme, UI mockups, story-boarding functionality or even developing small demos.
- Creating something we can show other people - hopefully a program created with the Hyperaudio Pad but also some new ideas.
Hopefully we can cram this all into 3 hours. Folk from the BBC, Universal Subtitles, Sourcefabric and other cool people are planning to be in attendance, which should make for some interesting crossovers and fantastic opportunities to consult and maybe even influence organisations in a position to use the stuff we’re making. Additionally the BBC are providing us with some fantastic media to work with.
All will be revealed over the weekend, book your place and get your eyes and ears ready to be part of the Hyperaudio experience.
The Hyperaudio Pad - a Software Product Proposal
Imagine
Imagine that making your own video or audio news programs was really easy.
Imagine if you could pull together news stories from various sources, combine them and publish the results in minutes.
Imagine that the story you made came complete with a transcript, was fully accessible and could be picked up by search engines.
Imagine that you could easily embed your story into a web page and that others could incorporate your story into new stories.
Imagine that viewers of you story could share any part of it in seconds.
Imagine all this and you are imagining the functionality of the Hyperaudio Pad.
Listen to a use case.
Watch the screencast.
Hypertranscripts
Currently, the process of putting together a media program, the process will probably involve some fairly complex audio/video editing software. The result - a fairly ’static’ representation. The whole process is time consuming, wasteful and inflexible.
By changing the way we think about media, we can create a new way of manipulating it. The Hyperaudio Pad allows quick manipulation of media and takes advantage of a form of media representation referred to as a hypertranscript.
When we tell a story we invariably use the spoken word, the spoken word can be transcribed, and once transcribed can be used as an accurate reference to the media it is associated with.
Hypertranscripts are part of a broader concept dubbed Hyperaudio by Henrik Moltke, they are transcripts hyper-linked to the media they represent, a type of fine-grained subtitle, they are separate entities from the media they describe, existing as a word-level aligned references expressed in HTML.
Tools and services exist to create Hypertranscripts, word level timing can even be approximated from subtitles. In the past I have used libraries such as Popcorn.js, jPlayer and data from the Universal Subtitles project.
The good news is that Hypertranscripts already exist, here are a few examples:
Screencast [youtube] of the Danish Radio Demo
Screencast [youtube] of the Radiolab Demo.
Quick and simple demo I put together.
Demos by others include: Minnesota Public Radio Demo, Voxallead News and Liris Interactive Transcript
Using Hypertranscripts we can:
- Navigate through the media via the text.
- Select and play parts of the media by highlighting the relevant parts of the text.
- Share parts of the media creating URLs that contain start and end points.
- Make our media more discoverable (via search engines)
- Make our media more accessible.
- More easily visualize the media.
- Combine, embed and easily integrate media (using simple tools)
The Hyperaudio Pad
The Hyperaudio Pad is a tool to allow users to easily assemble spoken word based audio or video from Hypertranscripts.
It will allow users to create their media by simply copying and pasting text from existing transcripts into a new transcript. These Hypertranscripts link to the actual media that they transcribe, so when parts of the transcripts are copied the references to their associated media are also copied.
Note that the media itself is not copied, just references to parts of it, the result is mash-up of video or audio and an associated representative transcript.
The tool will be :
- Web based, cross-browser, cross-platform (work on mobile devices) and open source.
- Simply presented, taking cues from minimalist distraction-free tools such as iAWriter.
- Intuitive and extremely easy to use, taking advantage of the text editing paradigm.
- Extensible - written in such a way that it can easily be built upon.
The interface should be clear and minimal, the user can search for and choose from existing hypertranscripts, open them, play them and copy parts of them to their ‘document’ all from within the same page.

Who is this tool for?
- Newsroom journalists who need to very quickly assemble media from different existing sources and perhaps adapt the result as news unfurls.
- Podcasters, citizen journalists and mediabloggers who want a free and easy way of putting together media programs or newscasts.
- Anyone who wants their resulting media programs to include a transcript for increased accessibility and visibility.
- Anybody who is happy for their results to be taken apart, re-combined or referenced by others.
How does it work ?
Hypertranscripts are essentially defined in HTML. The simplest possible example for the use by a tool such as the Hyperaudio Pad could be:
WORD-FROM-THE-TRANSCRIPT
Example:
burgeoning
Note, we can add to this format should we wish to include meta and other data, for example :
WORD-FROM-THE-TRANSCRIPT
(from Julien Doran’s MetaFragment proposal document)
Transcripts will contain a series of these marked up words each individual word containing enough data to describe it’s associated media and at which time in the media it occurs.
Note that copying the Hypertranscript into any text editor will result in valid HTML and so can be used in other tools and applications external to the Hyperaudio Pad.
It is likely that the user’s resulting transcript will reference several different pieces of media and so it may beneficial for the application to ‘load’ and possibly cache the various media sources in advance for smoothest possible playback. We can achieve this by parsing the transcript after every save.
Future developments could include a simple scripting language that users can insert between transcripts to make transitions smoother and even the possibility to add background music or sound effects for example:
[fade out over 5 seconds]
or
[background fade in 'threatening music' over 3 seconds]
and then at the bottom

You may say I’m a Dreamer
In order to start using the Hyperaudio Pad to its full potential we first need our media to be transcribed and to do this we need to make tools that make this easier and if possible free. However I believe that hypertranscripts deliver so many benefits that the incentive to transcribe media is high.
The Hyperaudio Pad is just one of many tools that could be built on the underlying Hypertranscript platform. To build this platform we should collaborate with others to :
- establish a standard markup for transcripts
- make the platform easy to build upon and enhance as new technologies become viable
- create a community with a pioneering spirit
- develop an ecosystem to facilitate the creation of a toolkit
During the course of this project it’s been a pleasure to find many other participants interested in the general theme of describing/transcribing media and utilizing the result. Over the last couple of weeks I have been collaborating with Julien Dorra, Samuel Huron, Nicholas Doiron and Shaminder Dulai. The excitement has been palpable and although only communicating virtually it felt like we were sparking off each other.
So I guess at least as far as this dream is concerned, I’m not the only one. 
Accessibility, Community and Simplicity
In last week’s Mozilla News Lab we were treated to webinars from Chris Heilmann, John Resig and Jesse James Garrett.
Chris (a Technical Evangelist for Mozilla), took us on a useful whistle-stop tour of HTML5 and friends, technologies that I certainly wish to take advantage of in my final project. I feel that there’s so much potential yet to be tapped, it’s difficult to know where to start, but I’ll definitely be using the new audio and video APIs and looking into offline storage. Chris also touched on accessibility, something that I want to bake into any tool I come up with. To me accessibility is interesting, not just from the perspective of users with disabilities but also because I hope to do is make news (and the tools to create news) more accessible to all people.
John’s talk was fascinating to me as a project coordinator of a JavaScript library, relating directly to the News Lab I found it interesting that many successful projects are a product of both good tools and strong community. The community aspect cannot be underestimated and is perhaps more important than the quality of the tool or service (which can always be improved by the community). I spoke about ‘Community Driven Development’ this year at FOSSCOMM and so is close to my heart, but to hear this confirmed by someone who has experienced success at the very highest level was great. I am now convinced that whatever ever form my final project takes, it will not only be community driven but it will have community built in, which to me means:
- Providing forums and methods of communication and feedback with the initial release
- Building extensibility into the tool so people can add functionality via plugins
- Encouragement of collaboration - make it easy for people to get involved
- Making sure that the documentation is comprehensive and clear (and can be contributed to)
- Fanatical support and encouragement
I also attended the ‘extra’ webinar given by Jesse James. In some ways this was the most useful to me as it focussed on designing the user experience or UX, something I’m keen to learn more about and who better to tell me than the author of The Elements of User Experience. It was fascinating to take a peak at how UX experts like Jesse approached the subject of design. I sat there transfixed as he broke down the process and discussed ideas such as psychology, emotion and how the user feels and their relationship with a given product or tool. Jesse spoke about the personality of a product and how users relate to tools as they would another person, using similar parts of the brain as they do when relating to people.
I really want the tool I create to be as simple as possible to use, so my question to Jesse was :
“Is it possible to make a product so simple that it doesn’t need a personality, or needs less? Or is the simplicity its personality?”
The answer : “Simplicity is a personality.”
Great. Hopefully I’m on the right track then.
Further Experimentation with Hyper Audio
Following the fun we had making the Hyperdisken demo, I was happy to be asked by Mozilla, in collaboration with Radiolab and SoundCloud to help create another demo to show off the possibilities of hyper audio. This time we had an excellent Radiolab program as audio material and we wanted to get a little more ‘involved’. What was required was an application that would consist of many of the features of the Hyperdisken demo but also integrate deeply with SoundCloud API, and on top of this something extra, something to catch the eye.
I was fortunate again to work with the ideas-forge known as Henrik Moltke, who collaborated early on with Paul Rouget to produce something he dubbed the ‘Word River’ - a CSS3 manipulated flowing river of words that dynamically picked up content from an HTML transcript. We were also keen to make a pure HTML5 based solution and Paul helped figure out the hooks into the SoundCloud API that would allow us to achieve that. We were also very lucky to be given a great design by the multi-talented Lee Martin, SoundCloud’s experimenter extraordinaire.
So with proof of concept and some visual bling firmly in hand I was tasked with making this baby fly. Luckily I had help. SoundCloud engineers were at hand to answer any questions and crucially we had great support and code contributions from the popcorn.js group. I also managed to talk jPlayer author and all round JS media guru and of course, colleague Mark Panaghiston into giving me a hand. So despite the tight deadlines we were pretty much set.
Henrik has already blogged about the ideas and functionality that make up the demo. I want to write a little about the technology used.
Although I found out in retrospect, not strictly essential, we once again used jPlayer as our audio base, we’re familiar with it and we can move fast using it. It also meant that we could take much of the functionality developed in previous demos and plug it right in. Again, the excellent Popcorn.js was the engine that drove all the time based display of text and images and dealt with the parsing of data. Steven Weerdenberg, active Popcornista from Seneca College, very kindly wrote a plugin that grabbed, parsed and presented comments (amongst other things) from the track we used hosted on SoundCloud. This is where the Popcorn framework comes into its own as a plugin oriented architecture, something we took advantage of when we converted both the transcript and the word river functionality into plug-ins.
So where did the data come from? Well again the transcript HTML doubled as the source for richer interaction when used by the word river plugin. I like this approach I have to say. It means you don’t have to be a programmer to come in and immediately understand the content and change it accordingly. I also like the fact that the transcript is a separate HTML file, it pleases the separatist in me and means that it works as a standalone resource. We also used the standard speaker notations as a type of meta-data, the word river plugin hiding these parts for the purpose of display but using them to colour code each speaker’s text.
This part of the transcript:
is used to create this ‘word river’:
and this interactive transcript :
Data-wise, everything else came via the SoundCloud API, this included their trademark wave-form, both ogg and mp3 audio sources and all of the comments. We also hijacked the comments to make a crude content management system. The idea being that any comments posted by the Radiolab account with references to images in them, were picked up and displayed as images in the main content area, and did not show up as comments on the timeline. If two images were present it meant they were square, one and it was ‘widescreen’ a blank image was used to remove images when they were no longer needed.
The last pieces of the puzzle and one we’ve still some polish to apply to, (if polishing puzzles makes any sense to you) was getting it all working on the majority of tablets and mobile devices. Since this demo didn’t use Flash this was actually a possibility and we got our web designer Silvia Benvenuti to come out of maternity leave and sort this out for us at the 9th hour, leaving me quite literally holding the baby.
This was a tough gig but all in all I’m happy with what we achieved, everyone seemed to really enjoy taking part in the process, and I certainly enjoyed bringing it all together. Hopefully it will inspire both program makers, designers and developers to come together and explore the limits of what hyper-audio can do. As Inspiral Carpets would say, moo!

Add a Stylish Audio Player to your Blog Without using Plugins
Admittedly, it’s a little crude, but it’s simple and it works.
If you’ve ever wanted to add an audio player to your blog post and didn’t want to go to the trouble of installing a specific plugin to do so, you can always embed jPlayer within an iFrame. The one-liner you need to achieve this would probably look a lot like this:
which could give you something like this :
Sure, it’s not that efficient, you may end up loading jQuery twice if it’s already included as part of your blog, but there’s the added advantage that the page will render progressively and you have a nice little sandbox to play in should you just want to alter the player.
I used to hate iFrames and shudder at their very mention, but I must admit I’m coming around to them.
