Remix Radio - a personalised listening experience.

Podcasts and iPlayer have done much to hand control of radio listening over to the audience. Now, instead of having to make an appointment with your radio to hear your favourite programmes, you can catch up with the programme on the iPlayer at a convenient time or, in some cases subscribe to the podcast and listen to it wherever is convenient; for me that used to be the long train ride to and from work, but now I walk to work in our North Lab that has changed.Ìý

Now that we have many radio programmes available when and where you want to listen to it, could we take that control one stage further and provide radio how you like it, remixed and reworked to your personal needs and preferences? I think we could, but it needs a change in the way we think about radio production. That change might also bring about improvements in efficiency in the production of radio, and TV programmes. We already need to make different versions for different time slots and different platforms and podcasts often have to be edited to remove or reduce the length of some of the music for rights reasons. It was this problem which originally lead me to propose a change in the way we make some radio programmes, but my work on the intelligibility of speech in broadcast sound has brought this subject to the fore again. I am trying to get people interested in an object oriented approach to production and get people thinking about what it could mean for our audiences.

The idea behind making this happen is to treat the individual elements of a radio programme as objects with their own identity and behaviours, much like the way data is represented as objects in object orientated programming. For example in a documentary programme you have a number of different elements, each of which play a different role in the programme. You might classify the different parts of the programme as follows:-

±Ê°ù±ð²õ±ð²Ô³Ù±ð°ù/²Ô²¹°ù°ù²¹³Ù´Ç°ùÌý

* interviews (multiple voices)

* contributors/interviewees (single voices)

* actuality/narrative sound effects (e.g. the sound of a key event)

* background sound effects (giving a sense of place)

* foreground music (illustrating part of the story)

* background music (reflecting the mood or emotion)

* linking music (giving pace and timing or marking a transition)

Currently all these elements are combined on a single timeline in an audio editor and rendered as an audio file, and alternative versions are created by re-editing Ìýthe original version. The listener can turn the volume up and down, jump around in the time line and press pause and play, but cannot affect the mix and the pace of the programme. Some players allow variable speed playback with pitch adjustment, but this makes the voices sound unnatural and harder to understand.Ìý

If, however, the elements of a programme were available as separate objects which interacted with each other in a defined running order then the listener could change the way the parts of the running order interact to make a programme more suited to their requirements. So, if for example my train journey is 25 minutes, but I want to listen to a half hour programme, the player could take all the elements of the programme, knowing which parts are narrative and which parts linking elements and reduce the gaps between the key narrative elements. Alternatively, if I wanted to slow the pace of a programme down to give me more time to think about what was being said, then the player could lengthen the linking sections by playing more of the music or sound effects that join the narrative elements still leaving the speech to run at the same speed that it was recorded.Ìý

Of course if you have a programme available as a series of separate objects then you could also change the relative levels to create a version with reduced levels of music and background sound effects, trading a rich soundscape for improved intelligibility for those who need it. People who hate the use of music in radio programmes could remove it altogether. Some people might even chose to remove the presenter. The player could contain your preferences for radio listening, so it always offered you your preferred listening mode, or it could react to the surrounding conditions as you move around, for example removing background sounds when you are in a noisy environment.Ìý

There have been some explicit examples of things like this in the past, for example allowed you to remix the song 'Digging in the Dirt', but in fact interactive and reactive soundscapes are commonplace as a part of computer gaming. Could we bring more to our audience by delivering object based linear content, as in radio and TV programmes? Could such an approach deliver sufficient improvements for our audience to make a change in the way we make programmes, along the lines of create once but publish for may different individual members of the audience?

    Hello Mike. What I want to do is to first is to find things easily in "sequences". Let's take though the night on R3. I want to listen to a particular item. Indeed I want to listen to a selection of these at breakfast. This doesn't look to difficult to automate

    Others I know would like the music without the words from R3 'Breakfast' itself, may be with very simple added alternative presentation ("Next is Blog's squeals in F minor!") So the objects would be the music, and the presentation the words etc (in two versions).

    Now this would be ok but DRM would kick in I'm sure if on Radio 2 I asked for all Dylan songs played over the last 7 days!
