About theory and practice

June 20th, 2013 by Graham Attwell

We have been running a series of workshops for the RadioActive project on developing internet radio stations. Part of this is about content and part around the technical side of streaming internet radio.

In theory the technical side should be easy – we take a series of feeds – from microphones, MP3 players, from a computer and mix them through a 8 track mixing deck before returning the signal to the computer, streaming it to a streaming server in London and hence to the internet. Indeed, so easy we thought it, that we designed the technical training as a breakout session from the main workshops.

We were wrong. The struggle with the technocracy has proved to be the main problem with the RadioActive project. And we came to realize the problem. We had showed people how to set the computer and deck up. But we had not explained the underpinning theories and ideas behind the audio set up. Fine if it all worked our of the box. But if it didn’t then without an understanding of what different components are doing, it is mighty hard to diagnose where the problem is.

Secondly we paid insufficient attention to the issue of leveling. Fairly obviously different inputs will have different levels (just like people – I am make an incredibly loud input). And one of the skills of the technician is leveling those inputs, both using presets during a sound check and adjusting the faders (and if necessary, the gain) during the broadcast. Also, post processing on pre-recorded items can help in getting a common level.
I could sort of operate the deck and system myself. But I had just picked it up as I went along and had no real knowledge of what the different buttons did.

And one of the issues was that people kept asking for us to tell them the ‘right’ why to do it, when , in truth there are many different ways to set the system up. But, once more, to understand the different possible set ups, which is useful when you discover you have left a key connecting cable behind, means having a more theoretical understanding of what we are doing than just following a diagram.
So we have revamped our technical training for internet radio. We have turned it into a two-day module and are experimenting with outcomes based accreditation. Dirk delivered the first workshop for the London partners two weeks ago. And I followed the same programme in Bucharest with our partners from Romania.

One of the critical aspects is we go far further into the theory, explaining what each part of the equipment does before even trying to connect it all up.
And it seems to work. Our Romanian partners broadcast a wonderfully smooth programme last Friday lunchtime. We still have some things to learn – we had forgotten to teach them how to use remote recorders. But the programme is getting set on the right course. Next step I think – is to try to produce some open educational resources and multimedia to supplement the face to face training

    To me this RadioActive-Project sounds really great. Now I’m really keen on listening to the results. Isn’t it possible to provide some links to get the productions? (O.k., looking for the content might be “old school” after Mc Luhan proclaimed that “the media is the message”…, but I stand by it).
    Thanks.

    Hi yes of course I should have added that Werner. Radioactive has a European portal for the different national partners involved in the project. These give access to the podcasts of the radio shows. The portal is at http://de.radioactive101.eu/.

    You can listen to a German language broadcasts on the German language part of the portal e.g. at http://de.radioactive101.eu/2013/06/26/002_raeu-special-events-kelt2013/

    Racial bias in algorithms

    From the UK Open Data Institute’s Week in Data newsletter

    This week, Twitter apologised for racial bias within its image-cropping algorithm. The feature is designed to automatically crop images to highlight focal points – including faces. But, Twitter users discovered that, in practice, white faces were focused on, and black faces were cropped out. And, Twitter isn’t the only platform struggling with its algorithm – YouTube has also announced plans to bring back higher levels of human moderation for removing content, after its AI-centred approach resulted in over-censorship, with videos being removed at far higher rates than with human moderators.

    Gap between rich and poor university students widest for 12 years

    Via The Canary.

    The gap between poor students and their more affluent peers attending university has widened to its largest point for 12 years, according to data published by the Department for Education (DfE).

    Better-off pupils are significantly more likely to go to university than their more disadvantaged peers. And the gap between the two groups – 18.8 percentage points – is the widest it’s been since 2006/07.

    The latest statistics show that 26.3% of pupils eligible for FSMs went on to university in 2018/19, compared with 45.1% of those who did not receive free meals. Only 12.7% of white British males who were eligible for FSMs went to university by the age of 19. The progression rate has fallen slightly for the first time since 2011/12, according to the DfE analysis.

    Quality Training

    From Raconteur. A recent report by global learning consultancy Kineo examined the learning intentions of 8,000 employees across 13 different industries. It found a huge gap between the quality of training offered and the needs of employees. Of those surveyed, 85 per cent said they , with only 16 per cent of employees finding the learning programmes offered by their employers effective.

    News from 1994

    This is from a Tweet. In 1994 Stephen Heppell wrote in something called SCET” “Teachers are fundamental to this. They are professionals of considerable calibre. They are skilled at observing their students’ capability and progressing it. They are creative and imaginative but the curriculum must give them space and opportunity to explore the new potential for learning that technology offers.” Nothing changes!

    someone was asking me about jobs as sandwich artists the other day. I though it was a joke. But no this is what subway call jobs as “popular options for part-time job seekers who are currently attending college or who just need a bit of extra spending cash”

  • RT @rafaelaganga Bit of context: the far-right Portuguese male presidential candidate criticised the female presidential candidate @mmatias_ for wearing 💄 on debates. A wave of 💋 is invading social media and showing this “facho” that: fascism in 🇵🇹 never again 💪
