ISEE how recording fits into engineering and how engineering fits into recording

Sorry, the title is a terrible pun on ISEE: the International Symposium on Engineering Education which I spoke at today. This is a bi-annual event where academics in engineering get together (this year at the University of Sheffield) to share ideas about teaching practice.

There were lots of really interesting and controversial presentations (the title of one of this afternoon's talks was Is attending lectures relevant anymore in engineering education?). I was presenting my thoughts on where in the recording studio engineering can (or does) take place. The paper that I wrote to accompany this presentation will soon be posted on the ISEE 2012 web site and I'll also put it on the dedicated web resource that will one of the legacies of this project. I focused on three areas of recording/processing: time-domain effects, dynamic-range control (particularly for mastering) and microphone array design.

The presentation was really well received (or maybe they just applauded at the end because I was the last to go on before lunch and their hunger - mine too, to be honest - was getting the better of them). I had lots of interesting questions and comments during lunch. Although sound recording is not something they usually cover at ISEE, it seemed to pique people's interest and I'm really grateful to all the delegates for their warm response and useful comments.

The paper writing doesn't finish there: I'm currently finishing off an interview for the Journal on the Art of Record Production and will then be starting on an article for an engineering journal. Before that I'm back at ISEE tomorrow to hear some more opinions and ideas on engineering and engineering education.

The final month!

Well, my eleven months on this fellowship are nearly up and, now that the teaching year has finished, the work rate for this project has now stepped up a gear from 'busy' to 'very busy'! Dave Beer and I are both writing up research outputs and I've been carrying on with interviews (most recently with four hugely influential figures in recording, see here), public engagement (most recently at the Big Bang Fair in York) and speaking at conferences about the project.

We've acquired many hours of interview and focus group data from well over two hundred people and this will live on after the fellowship in the form of an archive of transcriptions, papers and articles.

Right, better get back to work. I'll be back on here soon with details of how to access the archive and the latest news as the fellowship draws to a close.

Another free VST plugin for you...

Hi all

Another month, another plugin. As part of the Fellowship I'm releasing some free VST plugins that enable users to explore important areas of sound processing theory and practice. Last month it was panning, this month it's delay - an effect which recording engineers need to thoroughly understand if they are to be able to develop their own time domain processing tools (such as chorus and flanging units) from scratch. You can find the plugin (yes, it's free!) and the documentation here. Help yourself and let me know what you think!

There's more than one way to pan a source.....

One of the ways I want to engage people with the engineering that happens in recording studios is to provide free audio processing software that offers insight into commonly used tools that we might take for granted. For those who have any experience with recording, the pan control (short for 'panoramic potentiometer', believe it or not) seems a pretty much 'bread and butter' tool - it performs a basic, yet essential task for anyone not working in mono (i.e. the vast majority of us). It's one of those things that we don't usually think much about, but there is more than one way in which they can work and this has an effect on the quality of the 'spatialisation' that we do.

I've just finished a free VST plug-in (Windows only at present I'm afraid) which offers combined level and time based panning  (most, although not all, panners only offer level based control of source position). It's ready for use as a studio tool but also intended to be used for educational/experimental investigations into how panning actually works and the psychoacoustics behind it. In the accompanying documentation for the plugin there's some of the scientific background to the (apparently simple, you might have thought) task of moving a sound between two loudspeakers, along with some ideas for experiments and tests. You can download it from here.

Please give it try and let others know about it - whether they are teaching, learning or doing sound engineering. Feedback, as always, is welcome.

Things I'm learning

Last Friday I visited LIPA (Liverpool Institute of Performing Arts) to run a focus group with 3rd year Sound and Music Technology students. It was a fascinating session with lots of insights and ideas that haven't cropped up before. I learned a lot from these guys - which is the whole point of these sessions, so I'm really grateful to them and to LIPA for giving me the opportunity to chat to them.

This week I'm in Bristol for a four day course run by the Science Communication Unit at UWE, hopefully the embodiment of the adage that you're never too old to learn new things. Communicating via new media tools and podcasting techniques are amongst the things on the menu.

Your views

My piece in April's Sound on Sound has generated some really interesting responses. You can read the article here: When is an Engineer not an Engineer?

and here are some of the responses I've had, they are each fascinating and thought-provoking, just the kind of thing I was after. Dig in!

"Going back to the early seventies, it was not uncommon to find sound engineers wearing white coats - IBC and Lansdowne, Abbey Road, CTS spring to mind.

Certainly I think that the role of an 'engineer' has changed dramatically.  Back in the early seventies, a studio engineer was not expected to be or encouraged to be creative - that was the job of the 'producer'.  This itself was a similar bone of contention as many engineers resented the 'producer' and considered that the end result was totally the work of the engineer.  To emphasise the point, some would give the producer a fader labelled 'DFA' to influence the outcome . . . . (often justifiably!).

My first experience of working (as producer) was with one engineer at Lansdowne who simply refused to write any text on the channels on the mixing side of the desk on the basis that if I didn't figure out where things were appearing, I should not be sitting there in the first place.  I learned fast!

Also, apart from the core hardware, they knew how to mike up any instrument that was thrown at them.  There was also a training path of sorts through the 'tape op' system - that of course does not exist these days.

Most of the engineers that worked with at the time knew quite a lot about audio and recording, microphone techniques, etc - (they read electronic mags, not Q) and given that studio hardware was possibly less reliable back then, if anything stopped working, they needed to have sufficient understanding to fix the problem.  The more adventurous of them did indeed develop their own techniques to achieve astounding results - but this was more about impressing their peers than their clients!

Disc cutting engineers were even more technically savvy - which i think goes with the technology that they were working with  - and their coats were even whiter!

BBC sound engineers wre totally 'electronic engineers' and had no creative credentials, talents or musicality (actually there were a rare few who had musical abilities) and it still amazes me today that the BBC are totally unable to record and balance a rock concert satisfactorily - you can always tell when it a BBC recording - no vocals - maybe all bass or no bass at all - all hi-hat/no hi-hat - utterly lifeless and a travesty.  I dread to think how many rock concerts the Beeb has ruined over the years . . .

So, the blurring of the role of the engineer and the producer has taken place, plus it seems that with digital recording you can get away with far mor - or to look at it another way, get away with knowing far less.

There is much more of 'fix it in the mix' attitude than in former times.

Back in the early seventies, the company I worked for used to record six titles per session - and I had just four hours to mix twelve titles (from 8 or 16 track) - recently I had the miserable experience of working in a west end studio where it took the two house 'engineers' over two hours to set up the miking of a drum kit and routing stuff through the desk . . . . . . yes, times have indeed changed . . . ." (George Barker)


"
My training is in research science, but I’ve always had a keen interest in music; starting from the childhood piano lessons, through playing guitar in indie bands, until I discovered deep house music and moving more into production and putting together a home studio. I am currently an assistant professor in virology, but continue to produce EDM. I like to think I’m the only person who’s worked at biosafety level 4 and has a label deal!

To begin with, I have no problem with the use of the term engineer in an audio recording context, regardless of whether someone has a degree or attained chartered status. You can be a great artist without going to art college, and look at the great science that has been done in the past by hobbyists, and the clergy in particular. George Stephenson lacked any scientific education, invented the safety lamp by trial and error and was fairly convincing at designing steam locomotives. I think the current sociological climate, where so many have access to university, has made a lot of people think that, if you don’t have a degree, you can’t possibly be considered equal to those that do.

I also think that the person you quoted in the article who said “the audio ‘engineers’ you describe are generally not scientifically trained”. I don’t know of any engineers who are scientifically trained; that is not their job, and it shouldn’t be.

Science is an abstract concept, which uses experiment to derive a set of conclusions, which establish a working theoretical framework. Engineering is concrete; engineers take this framework and apply the knowledge to a tangible output. The scientists come up with the rules of fluid dynamics, the engineers build the plane, the scientists work out the laws governing transmission of forces, the engineers build the bridge. Building a bridge is not a place for experiment.

As for Drew Daniels’ comment about miking a guitar amp, for from being non-scientific, that is the essence of scientific discovery. Pure experimentation is what science is. If you look at the philosophy of the scientific method as put forward by people like Karl Popper, knowledge can only come through experience. If you don’t try that other mic at that other distance at that particular angle off the axis, you can’t know if it will sound better or not.

The major sticking point I see with the term ‘engineer’, is that is purely, and perhaps arbitrarily used to define the people either side of the glass. You can make a very convincing argument that hearing a guitar part and knowing that it needs a 3 dB peaking cut at 2.6 kHz and that compression from a Distressor will sound better than an 1176 is an artistic skill, rather than an engineering one.

My own personal thoughts are that the recording engineer is artist, engineer and scientist; it takes intuition, technical knowledge and knowing how to experiment to do the job. Engineer is just a job title. They may not be able to play the musical parts, they may not be able to build a mixing desk, they perhaps inhabit the middle ground, maybe they should be ‘artineers’…" (Fynn Callum)



"I am an artist, not an engineer.

I have owned 7 and currently own 5 mixing desks. I am self taught but that means learning from everybody I work with and from reading listening and watching. I try not to describe my self as a sound engineer, but the moniker chases me around. I also feel the word musician to be rather grand in my own case. However, I get paid to play in bands alongside excellent musicians and record and mix, and teach as good audio practice as I can. As long as I am honest and my skill level is sufficient for what I attempt, I am ok. God help me if I ever stop learning.

For a week, some years ago, I worked as the designated sound engineer on a youth project at Abbey Road. I looked cluelessly at the huge consoles in the two studios we used, never having encountered anything on that scale before. When introducing myself to the house assistant, he said "Ah, so you are the sound engineer", and I  knew I was in trouble and out of my depth. I soon earned his scorn, and if I won it back it was by project managing, getting my hands on when appropriate and leaving them off for most of the time. I did a good job but the title of sound engineer was the wrong one. A misnomer.

I met John Oram recently. I absolutely consider him an engineer. He knows what goes on under the hood and at the controls. I am still a something though. I am more of a creative contributor who uses recording and mixing. Perhaps I am a sound designer. 4 years at art college and a masters degree in sonic arts would seem to make that a far better title and helps to expose the engineer myth. Mind you, I drive a car. I neither engineered it nor designed it. Maybe I am a sound navigator. Who really cares? 

Last year I made a sound art piece on my computer, uploaded it to the net and it went viral. The original blogger described me as a DJ. Something of an assumption, but more honestly it was a journalistic device to help describe me, where he could perhaps have said  'sound artist'. One subsequent critic said "where do these DJs get off?" Well I did not call myself a DJ at all.  So if you want to call me a sound engineer, feel free, I can't stop you. And you can't stop me messing with mixing desks." (Paul Chivers)



"First off, you need to know that I am from Canada, in the province of Quebec, where we have an association called the Ordre des Ingénieurs du Québec (roughly the Quebec Engineers Board) that protects the use of the term Engineer. To become anengineer, you have to obtain credentials that are approved by Canadian Council of Professional Engineers that define the study program required to use the title. This protection has made it impossible for people to call themselvesSound engineer in Quebec (the Council does not have a Canadian program for that, to my knowledge) and, as an example, Microsoft was forced to retire the term Microsoft Certified System Engineer (that I have passed) in Quebec (although MCSE is tolerated). I myself have studied Electrical Engineering and am part of the OIQ.
As you could guess from my reading of Sound on Sound, to which I actually subscribe, I am also deeply interested in sound and music. Actually, I originally had studied in engineering because I dreamed of designing and manufacturing sound synthesizers. The opportunities that followed my degree made it that I became a computer systems consultants and I worked very successfully for over 20 years in that field, until I thought I needed some change so I went back to school in 2008 to study audioengineering at a college level.


During this 20 years career though, I was passionate enough about music to educate myself and learn the tools of the craft: I had a personal computer running what was then Cakewalk sequencers in 1988. It must have been version 2 running on Windows! So I started with outboard synths, MIDI and grew progressively has the software upgrades got to market (Cakewalk Pro, then Cakewalk Pro Audio, and then Sonar) to learn about all the technical stuff involved in recording, mixing, mastering music using these tools.

And so in 2008 Im back on the school bench with kids 20 years younger than me, mostly interested in producingbeats with at best a secondary degree (which turns out to be 11 years of school here) so with very little technical, mathematical and scientific knowledge; and teachers just about my age (sometimes younger obviously) with no degree whatsoever but that had had a career (or something resembling it) in producing music in the Quebec music industry. I took this decision with the intention of changing career and make a living in something I loved. This is the place I understood the difference between engineers and non-engineers.

Most of the teachers were really musicians that had learned to use audio gear and computers to record their own music first and then work in studio to record others. They were pretty good at that and I enjoyed learning from them in general. But, I was told falsity more often than not when the course were very technical (think of artsies presenting the Nyquist theorem, acoustical principles, or digital compression techniques to an engineer). And also, these folks had a very negative opinions of engineers in general. They tend to look at me as too technical and notusing my ears enough to a point where I sometimes felt they were condescending toward the profession.

What I found the difference is, is a matter of efficiency. People that approach recording, mixing and mastering from amusical perspectiveear the results they want to get, but they will do a lot of tweaking and trial and error to get there; sometimes taking path that are actually pulling them away from the result. Evidently, people get better with experience, so I could not compete with the teachers in terms of efficiency. But humbly I could get a recording, a mix or a mastering job done in a quarter of the time my colleague would. Thats because engineers, to the contrary I think, will try to define a path to get to the results and follow that path, making changes as required in the process. The former are more exploratory, sometimes giving birth to very good ideas that we engineer will not find, but at the expense of taking much more time in the process.

It might not be the same everywhere, but to me it was a revelation.

After finishing the course, I tried to get a job into recording studios or gaming production facilities, but I could not compete with the low wages that my colleagues were commanding. So I decided to continue doing music as an hobbyist and pursue my former career in technology. After all, it is not so bad being an engineer, even if it is not an audio one!" (Sylvain Roy)

Final call for consultations

Since I last updated the blog temperatures are back on the right side of freezing - bringing blossom, birds and slightly longer reverberation times to my part of the world.

I've got two more consultation events in the diary: one at the Liverpool Institute of Performing Arts, where I'm also going to give a talk on the latest research that we're up to in the Audio Lab research group at York, and the second at University of Surrey with students of their Tonmeister course. It will soon be time to shut up shop on this part of the Fellowship and move on to the next phase of writing up and analysing everything I've gathered at these events. If you think you'd like to host one of these at your institution then please let me know via email, but hurry because time is running out to get these organised.

In other news I'm off to the CoDE (Cultures of the Digital Economy) conference in Cambridge next week to present a paper about Engineering in the Digital Recording Studio and I've had an opinion piece relating to the project published in Sound in Sound. On Thursday I hosted sessions for school children from Halifax and County Durham on 'The Science Of The Studio" as part of the University's annual Science Trail event. We looked at how time delays and energy differences between loudspeakers create 'phantom images' between them.
