Identity via commonality

Just a quick thought… I’m new to this whole blogging thing, despite having dabbled with similar features in Apple’s iWeb software over the last few years. I think it’s fair to say that this blog is something of an experiment for me, with the aim being to see what kind of reactions I might create in people based on what I write.

One of the struggles I’ve had in putting this together is finding the right visual theme for the site. I care almost as much about visual presentation of media as I do about audio quality in general, so finding the ‘right’ look from a bunch of free, online common themes is a challenge.

So along came a blog announcement on WordPress earlier today about the new ‘elegant grunge’ theme, which I’ve applied to the site. I think it fits the slightly eclectic, rough-around-the-edges content I seem to have found interesting enough to post lately.

Maybe I’ll stick with this one for a while…

Truth doesn’t always need solving, nor does it always fit in a neat little box.

I’ve been plagued by emails recently from companies with whom I’ve raised support tickets and have failed to see the cases resolved to our mutual satisfaction.  Presumably these cases are festering deep in the guts of their CMS systems, which have been set by management to automatically close any cases that have been inactive for a certain period of time, marking them as “Solved” and emailing the end user.

From a management perspective this seems a great way of reducing the number of “pending” or “unsolved” cases held in their systems, which undoubtedly makes the statistics look good.  As an end-user, my experience
is usually that the case is not at all solved, and the reason for the lack of action is usually due to either the customer or techsupport department being overloaded and treating the case as a low-priority item.  Alternatively the customer gives up all hope of the company either caring about or being able to solve the problem, and goes on to buy another solution.

For those of us working in, designing for or managing technical support roles, this daft situation highlights the need to allow for the fact that some cases are never “solved”. We need our “unresolved” and keep details of why, if only for future reference during either further support or development.  We need to understand that the truth doesn’t always want to be stored in neat little boxes, nor does it always need solving.  Just acknowledging, accepting and archiving by some means.

Meanwhile where I do some across emails in such “unresolved” cases, I’ll simply bounce them back to keep the case open until a human reads the case and deals with it in a more meaningful way.  It takes just a few seconds to send a reply saying “you say it’s solved.  It isn’t”.  It’s not about being awkward, it’s about wanting to make sure that companies can’t say “everything’s great.  We couldn’t be doing better” when the end-customer experience can be rather different.



New music: Innocence 2010

I spent much of this weekend re-writing an old tune of mine from some ten years ago – perhaps more.  Yes, the song was originally written for a girl (I thought I was *so* romantic!), and that relationship never came to anything.  While I was working on this new version, I was thinking about what I would tell my ten-years-younger self, given the opportunity?  Would I actively help him make sense of everything he’s seeing, thinking and feeling?  Would I just listen?  Or would I perhaps just say the simple words “it gets better”?

Innocence 2010 by Abstractnoise (MP3)

In taking on the re-write, my main aim was to attempt to get to know a combination of music software on my mac,  so the whole thing was produced in Reaper (a nice MIDI/Audio sequencer), FreeAlpha (making most of the sounds heard in the track) and SampleTank 2.5 (which provides the 808-a-like snare and hats, and the mellotron which I absolutely adore!).

For those who remember it, I hope I’ve added to the story without losing too much of the slightly childish, simplistic feel  of the original.  Ten years is a lot of life and musical experience…

BBC to launch “HD” sound on Radio 3 iPlayer

It seems that the BBC is due to launch “HD” audio streaming for its online radio broadcasting, starting with their Radio 3 service in December 2010. They’ll also be running a trial of the technology for this year’s Radio 2 Electric Proms on 28th to 30th October 2010.

Currently we’re used to listening to many BBC national and local stations on iPlayer, most (perhaps all) of which use 128Kbps AAC encoding in stereo. These streams have not been running in their current form for all that long, and brought significant improvements over the previous up-to-56Kbps RealPlayer streams both in terms of quality and accessibility, making hi-fi playback of online radio streams pleasurable for the first time, and certainly a big improvement over the audio quality DAB currently offers.

Initially the new “HD” stream will only be avalailable for Radio 3, and will use 320Kbps AAC-LC stereo encoding. Experts with more knowledge than I can explain what the difference means from a technical perspective, and therefore why it is seen as such an improvement. I’ve not yet listened to any of the trials that were arranged for this years Proms, but in my work I find myself playing with many different audio and video compression systems for online distribution and I have to say that there is a significant difference between 128Kbps and 320Kbps AAC audio. The former is “good enough” for many, but the latter is so close to either “lossless” or “PCM” in various forms that many won’t be able to tell the difference between compressed and uncompressed sources.

This is a huge step in the right direction – digital audio broadcasting in the UK has long suffered demonstrable quality issues that are easily audible even on small DAB receivers and laptops, so anything that kills these audio data compression artefacts is a very good thing. Despite the lower-quality MPEG encoding currently used by DAB, I’d love to see them lose some of the fringe stations and put the extra bandwidth to better use on the national stations.

Certainly I’ll be very interested to hear the new HD streaming during the Electric Proms – and will report back here with my findings.

Live sound: Fine-tuning channel EQ

I’ve just been unexpectedly covering sound duty for our two morning services, and took some time to really play with the EQ facilities offered by our new desk, particularly during the sermon.  Above is a picture of the EQ section for the radio-mic I was using, and it looks pretty extreme, huh?  Lots of huge cuts if the gain indicators (the red LED’s at the bottom) are anything to go by.

Now, if someone showed me their analogue desk and I saw a channel EQ with quite so much taken out as shown, I’d have taken them back on for more teaching about gain structure and microphone choice/placement among other things. On most analogue desks there’d be nothing left of the original signal. You’d end up with an EQ curve looking a bit like the yellow line shown here:

Extreme EQ, “standard” analogue desk style. Low shelf frequency is around an octave higher here than most analogue desk EQ, and high shelf around two octaves lower. The yellow line goes off the lower scale, it’s so extreme.  You’d need to add at least 12dB of gain to the fader or pre-amp to get the original signal energy level back, assuming you don’t distort the pre-amp or other areas of the desk!

On our iLive system, things are a little different, as shown in the image below. We now have the ability to notch out problem frequencies with much more precision, mostly because we now have the ability to create very narrow (in terms of the frequency range affected) EQ filters. For live sound, this means we can make deep, narrow cuts to problem (resonant) frequencies and leave the rest of the signal alone.  This means that the problem frequency bands can still be attenuated, but without losing anywhere near as much of the overall signal energy.

This allows us to run with less gain at the pre-amp stage, which makes for less background noise and less chance of distorting any audio stage in the desk, whether digital or analogue. Because I’m not having to boost the pre-amp gain, I’m not changing the gain structure in any way, which is a Good Thing™ for too many reasons to detail here.  Because I’m not boosting either overall levels or particular frequency bands, I’m not introducing new potential feedback points to my mix – again a Good Thing™.

Of course, this benefit isn’t unique to the iLive system, but I used it to illustrate the problem as a) I have one and b) I happen to like how it sounds!

Random tip: Cleaning a French Press

 

Cleaned French Press!

Cleaned French Press!

 

On a more positive note than I normally tend towards, I thought I’d post up a quick tip about cleaning stained French Press gauzes, as shown in the photo above…

I’ll admit I’m not always the quickest at getting things like washing-up done, so occasionally my coffee-making paraphenalia can start to become a micro-biosphere.  This sometimes leads to thick deposits left behind on the filter gauze that is resistant to all known forms of scrubbing or cleaning agents.

Except biology.

Sometime between walking my wife to her train this morning and returning to our flat to get ready for the rest of my day, I had a brainwave.  Coffee is a biological product, right?  And okay, whatever grew in the pot is also biological, right?  So why not use some kind of biological agent to break down the stains?

Now where would I find a (near) free source of suitable enzymes?  When I loaded the washing machine I hit upon the answer – we use biological washing tablets for laundry – perfect!

With that idea fresh in my mind, here’s what I did:

  • Put some warm (<40 degrees Centigrade) water into the press, measured by being warm to the touch.
  • Drop one biological washing tablet into the water.
  • Allow tablet to dissolve, then stir the solution.
  • Insert the plunger, so that it sits submerged halfway between the water surface and the bottom of the press.
  • Leave for 15mins.
  • Pull plunger up and down a few times.
  • Leave for 15mins.
  • Stand the French Press in the sink, then fill the sink with enough warm water (as used for the solution) to match the top level of the solution in the french press.  This sets up a warm water bath, and helps maintain the bio-active solution at a good working temperature.
  • Leave to stand for the day while we are at work.
  • On returning home, pull plunger up and down a few times, empty the solution from the French Press and rinse with clean water.

PRESTO!  One restored French Press, that uh… now smells a bit like our clean laundry.

Review: Jarre 101010 @O2 Arena, London

intimate, and very much alive.

Jarre 2010 tour graphic

Jean Michel Jarre has long been a hero of mine right from when I first become musically sentient at around five or six years old. Since then I’ve enjoyed much of his studio-recorded material and had always wondered how it had been put together.  I had even been taken to see him live in London at his Destination Docklands show back in 1988 – where as a family we watched the drier Saturday night performance, rather than the Sunday night whose footage eventually got released as the (awful) official Mike Mansfield video. And so with those brief statements of bias over, on to the concert itself.

crowd

All age groups and ethnic/cultural backgrounds were represented, and much more univerally than one might find at most gigs.  There were families, couples, groups of friends, all talking quietly before the gig began. It was a shame that the majority of the crowd didn’t seem at all responsive except for the .  Sure, some arms were waving and a few people danced their way through Chronologie 6, but on the whole the crowd was terribly English.  It was more like being at a specialist classical Promenade than a pop concert.  Which is perhaps appropriate given Jarre’s roots and following.

music

I was pleasantly surprised by how little modern material was included.  Highlights from all albums up to and including Oxygene 7-13 were played very much in their original styles, with perhaps some hints at more modern sounds and technology.

Some lines from the Equinoxe numbers were missing, particularly the vocoder sections, which made me wonder whether Jarre et al. had somehow forgotten how to create the original sounds.

Otherwise the pieces took on a new life in their freshly-human-played glory.  There were some glitches, some tuning and timing errors and perhaps the odd mis-keyed note or two here and there, but I felt if anything these added to the “live” and “intimate” aims for both the performance and as it would appear, the whole 2010 tour.

The backing musicians were enthralling to watch, and their restrained minimalist motions looked very much more “Kraftwerk” than Jarre himself, who took on the persona of a mad scientist plotting and doing all kinds of terrible evil in a B-movie labroratory. A contrast that worked very effectively, and added a certain depth to the music we were hearing.

Success.

sound

The sheer depth that those synth sounds have in them was simply astonishing.  Every instrument was allowed full range of the sound system, subs and all.  And as if the impact of percussion and bass lines wasn’t enough, some of the leads were seismic.  Admittedly we were sat right by the sub-woofers, but even when they weren’t moving the earth, the warmth and immediacy of the analogue synths was immediately obvious.  As a case in point, any sound that used white noise as a basis for further synthesis was evident by the subs waking up even for cymbals – something one would never hear in a front room at even high domestic listening levels.  Standard mastering processes simply wouldn’t allow for that kind of depth.

Further, the dynamic range was immense compared with most concerts I’ve attended where sound reinforcement was in use.  The sound operator was clearly having a great time, and that meant the full impact of the music came through without having to blast anyone’s ears off.  Sure, there were loud passages, but this gig was mixed for impact and that really showed.

Alas there was one negative note:  those of us at the sides really didn’t get to hear much of the stereo image.  Many of the timing cues in Jarre’s percussion programming tend to be spread across the stereo soundstage, so we occasionally got lost!  A mono’d mix to the sides would have worked much better for us at the risk of losing some depth.

Over all?  Success, with some areas I’d love to see improved – particularly the distribution of the stereo field around the auditorium.

laser harp

Jarre at the Laser Harp

Allegedly “revised” according to the programme, though I’m not sure how?  The one at Docklands was a much more structral, fixed affair, that much is true.  But the one I saw this evening was markedly similar to many I’ve recently seen on YouTube.  Perhaps this tour has been running long enough that I’ve become accustomed to the new version, but I’m sure this isn’t all that new.  It certainly looked awesome, and some how having such a visual instrument was a key element to the show. Okay so perhaps Jarre is just showing off for the sake of it here, but let’s face it, if you could get that kind of sound out of lifeless electronics, why wouldn’t you try to make it look cool at the same time?

Verdict:  Cool.

theremin

Jarre plays the Theremin for "Babel's Tower".

Wow.  My jaw hit the floor pretty hard when he brought that thing out.  It’s a rare treat to see anyone use one of these, let alone at a live concert.  The soul and emotion he gave that instrument frankly brought a tear to my eye.  Astonishing to watch, all the more astonishing to hear the atmospheric and emotive effect it could have.

Verdict:  Overwhelming. And cool.

(I’ll not mention the electic accordion).

video

Equinoxe "faces" video

The use of video effects was quite understated, perhaps to help support the much more intimate feel of the tour as a whole, and if that was the brief then it was very successful.  There was an interesting moment where “eyes”, particularly those of insects, were a dominant feature for some of the more modern Oxygene 7-13 material featured, and I didn’t quite understand where that was coming from, nor what the possible message might be.

Stats for Jarre's UNESCO solo. I don't remember that he gave a title for it?

Jarre played a solo piece on what looked like a Triton, dedicated to the work of UNESCO.  The piece alone was moving enough, but the simple animated slide behind it (shown above) put some commonly-found statistics and environmental issues into startling perspective.  Simple, and very effective.

Where live footage was used it was usually processed into a film-noir, German expressionist look, which looked both futuristic and incredibly old-fashioned at the same time.  Very much a nod to the old “Industrial Revolution” theme of the 80′s Docklands event.

The closing song (Calypso 3) made use of Jarre’s trademark Keytar, and the live footage focussing on him with a Cyanotype monochromatic effect was incredibly striking, and even more so with the full-width rear-projection screen.

A great use of the current technology, and probably some prototypes the rest of us mere mortals might be able to afford in 5-10 years.

lighting

Moody, yet understated lighting!

Like the video graphics, the lighting was understated compared with what previous Jarre concerts have been in the past, but a very full palette of both colour and texture.  If there were a word I’d associate with the design, it was “tight”.  Like Jarre’s music, everything was there in its place, for a reason.  Anything else was left out.  In particular the use of shuttered lighting to use the Mellotron backs as wash-light sources was particularly impressive, not perhaps in itself, but certainly as an example of the fine detail that went into the design.

Multi-coloured laser effect (Click to see a bigger version)

As now seems compulsory for a Jarre concert, we saw extensive use of lasers and similar effects, giving the earlier material a “Tron”-like look that felt completely appropriate.  The lasers were multi-coloured (perhaps visible in the above image, the “white” beam actually made up of red, green and blue beams merging together) – a first for any gig I’ve seen!

At no time did I feel the lighting was distracting from the showa job well done, I think.

summary

In all then, the show was very much worth both the wait and the money.  I’d recommend the show anyone with even the slightest interest in Jarre himself or the electronica genre that he has helped create.

If you get a chance to see any other leg of his 2010 world tour, go see it!  You won’t be disappointed.

Coming up: Jarre 101010 – Live at the O2 London and online

Really looking forward to this concert – and interesting to see that things are happening online too, with “something special” or “something strange” happening on the night depending on which source you read/watch.

Having been to the Docklands concert back in 1988, I’m really interested to hear how his live music performance has progressed since those days, as well as how his use of the visual arts has progressed. My ultimate question will be… does technology help or hinder the artist?

Well, the tour page of his website is here, if you’d like to follow the action!

Review: Bit Literacy – Mark Hurst

As I return from a weekend get-away spent in Oxford, I must confess to having spent my reading time in a rather geeky way – reading about how to be ‘Bit Literate’.

“Bit Literacy” is both a book title and a descriptor for being efficient in our handling of digital data. The benefits of being bit literate in some manner of speaking can apply equally to domestic and commercial situations and are mostly common sense, such as ‘never send hundreds of photographs by email’ or ‘always have a backup’. ‘Consider the user’ and ‘consider your future self’ seem to be constant reminders and motivators through the text.

In his book, Mark Hurst describes quite concisely the problems most computer users describe. His prescription is essentially a good dose of common sense, but some aspects of his book are less than obvious, and essentially involve taking the time and discipline to only use proprietary tools or filesystems (such as Microsoft Word, or pretty much any email client) when absolutely necessary, and to use simpler, more open methods such as creating and storing most textual data as ASCII .txt files from Notepad or TextEdit.

Hurst writes in a way that appears to draw more from experience and experimentation than commercially-driven bias. While some if his suggestions seem outlandish to many, I will certainly make a point to try out his methods in the coming weeks – many of them appeal to my own ideals and filekeeping methods anyway. In time, I predict I’ll be recommending all commercial organisations (my own employer included) train their staff with such methods and enforce the use thereof.

Watch this space. Thank you Mark for your informative guide.
