The Art of Listening Part Two

The Art of Listening Part One

Mixing sound is both an art and a science – a collaboration between the feeling, intuitive right-brain, and the analytical, logical left-brain. Last month I talked about critical listening and how, as a monitor engineer, to interpret a musician’s requests. This month we’ll examine how to separate different audio elements within a mix, and I’ll describe how I EQ individual inputs. It’s by no means the only way, but in 20-plus years of trial and error, I have found this method to be the most efficient and effective for me.

Monitor mixes need to be easy to play an instrument to / sing to as well as sounding good. They particularly need to provide clear, functional information about pitch and timing, so it’s worth considering what is supplying useful information to a monitor mix, and what is unnecessary filler. For example, some sounds are useful for an artist to pitch to or time to, or they carry a signature riff within the song; other sounds might create a pleasing fullness for FOH but reduce the clarity of a monitor mix and make it hard to play along to. This is especially true when it comes to hard-drive tracks – some elements are more useful than others. Sounds like strings and percussion are typically pretty helpful; effects might be less so. PFL is your friend when it comes to identifying different sounds, particularly when multi-tracks are involved because the sounds are likely to change from song to song. Frequent PFL’ing of your inputs will familiarise you with what’s coming in, and helps you to identify useful audio information.

Judicious use of the most basic of EQs – a high pass filter – goes a long way to eliminating unnecessary frequencies that can muddy a mix, and it’s my first port of call in the EQ process. Consider the range of frequencies that each sound exists within and where the defining characteristics of that sound lie in the audio spectrum. Let’s take a hi-hat as an example – there’s not much useful information in the lower frequency ranges, in fact, the mic is picking up spill from the rest of the kit – so it’s good to clean up and get rid of the extraneous low stuff. Personally, I set a HPF at around 600Hz for cymbals, but try it for yourself – solo the mic, use your ears and see what you think. Follow the same process with your other inputs, and tidy up anything that isn’t providing useful audio information – play around and consider where you might set hi-passes for different drums, vocals and so on. You can do the same thing with lo-pass filters, but be very careful with these. A bass guitar for example is primarily low frequencies, but if you set a LPF too low, you’ll lose a lot of the ‘attack’ – the finger-on-string sound which gives a bass its definition – because that attack sound is actually quite high up in the frequency spectrum. (Try boosting a bass guitar in the 5kHz region and see what you notice.) Likewise vocals – most of the action is in the 300Hz to 3KHz range, but set your filters there and you’ll lose low ‘body’, as well the ‘super-Ks’ – the very high harmonics which give a sound its ‘air’. So listen, listen, listen and experiment!

Identifying frequencies is obviously a vital tool for a sound engineer, and learning this skill really is just practice and repetition. I spent many hours in a PA company warehouse with a mic and a graphic EQ, making a wedge feedback and gradually learning what different frequencies sounded like. Once you’ve got a decent idea of that, you can start to refine your skills using the parametric EQ on the channel strip of the desk, and this is the next EQ tool after the HPF for your inputs. My preferred way to precisely locate a frequency is to solo the (muted) input on cans/IEMs, set a filter with a tight bandwidth or ‘Q’ around the frequency I’m looking for, and boost it quite hard – say by 10dB. Then I sweep the filter up and down slightly until the frequency I’m listening for me pops out (you can close your eyes as you do this if you like, to make sure you really are using your ears and not letting your assumptions fool you!) and with that identified I can then reduce or boost it as appropriate. You might want to keep the Q really tight if it’s just one frequency that’s over or under-represented (which is what I’d usually do with toms), or you might choose to do a big old scoop – my typical kick drum EQ has a wide low boost for ‘boom’, a wide high boost for ‘thwack’, and a wide gap in the mids where there’s nothing useful or sonically pleasing going on.

Approaching EQ like this means that you start to carve an audio landscape, with different instruments occupying different areas of the frequency spectrum. In my experience that gives a nice clarity and ‘separation’ to your mix – the opposite of audio ‘muddiness’. It’s all about trial and error, so grab every opportunity you can to play around – the advent of virtual soundcheck playback systems has made it easier than ever to refine your skills, so if you’re lucky enough to have access to such a system, make use of it. Tip – most high-end desk manufacturers have demo rooms set up with exactly that, and are usually very amenable to potential end-users coming to try out their equipment, so don’t be shy about calling them up and arranging a session! It’s a great way to hone your craft, learn different desks, and make contacts.

Until next month, SoundGirls – happy listening!

The Art of Listening

How often do you listen to music? I don’t mean throw some tunes on in the car or play the radio in the background, I mean really listen…. the kind of listening where you give the music your full attention, focusing on the qualities of individual sounds and noticing things which are not immediately obvious. That distant layered guitar chord; the faint timbale in the background; the different harmonies of the violins. The nuances of the reverbs, the tuning of the drums, the positioning of sounds within the stereo image. How often do you do that?

If you’re aspiring to be a successful professional sound engineer, I hope the answer is ‘a lot’.

This is the art of critical listening; the vital skill that every mix engineer needs, whether in the recording studio or TV suite, at front of house, or behind the monitor desk. Anywhere you find yourself with your hands on the console, you need the ability to zero in on sounds with Jedi-like focus, to discern what they add (or not!) to the overall mix. Only then can you begin to manipulate them to enhance the experience – because simply adding more and more sound sources indiscriminately can leave you with a nasty audio ‘mud’ from which it’s difficult to extract yourself. It’s a skill that is honed over time, but the good news is that can you start anywhere, with no fancy gear whatsoever.

You can start right now, by listening to lots of different styles of music on lots of different speakers and headphones. Never gotten into classical, reggae, country or samba? Give them a try!  I usually, listen to downloads in your car or on headphones? Beg or borrow a decent pair of domestic stereo speakers and play a favourite album on CD or vinyl. Clear your space of all other distractions and just listen. Prepare to be amazed at all the details you never noticed before. You can make it a game by writing down every sound you identify (if you don’t know the instrument, don’t worry, just describe the sound – it’s for your eyes only). Then try drawing a picture of the stereo image as though it’s on a movie screen. Is there a guitar sound to the left? A cello to the right? Are some things higher in the air, or nearer to the ground? Do you feel like some sounds sit further back, or closer to you? Do you perhaps start to feel that the stereo image is more 3D, than flat left and right?

Did you just blow your own mind?! I know I did, the first time I tried it – I can still remember the exact room I was in, and that was 25 years ago!

Doing plenty of listening practice puts you a step ahead when you’re eventually behind the desk. As an engineer, a smart move before working with a band is to get a copy of the proposed setlist and listen to all the songs, many times over. Obviously, if you’re mixing several bands for one day only at a festival then this isn’t practical, but if you’re doing repeat gigs then it’s really helpful to understand what the original song sounds like and what the musicians are used to hearing. You won’t necessarily try to recreate that – a monitor mix is functional as well as pleasant to listen to – but the reference point is invaluable.

There’s another sort of listening which is also vital, particularly for monitor engineers, and that’s the art of listening to what your artist is telling you. This is where we get into the realms of sound engineering as psychology!

I’ve written before about the importance of developing trust between the monitor engineer and musicians, and a great way to inspire that (after doing your pre-production homework and introducing yourself in a friendly and confident fashion) is to really listen to what they are telling you. (A wise person once said that we have two ears and one mouth for a reason!) Make eye contact, give them your full attention, and check anything you didn’t quite understand. Repeat keywords back to them, to make sure you’ve got it. This not only gives you a better shot at meeting their needs quickly but also helps them to feel heard – and believe me, that is a huge part of forming trust. Do you know those people who make you feel like you’re the only person in the room? Be one of those people!

Of course, the tricky part of monitor engineering is that you need to make every person on stage feel like that simultaneously, and if they’re all talking to you at once, that’s no mean feat! Use the ‘one at a time, but I see you’ approach – stay with the person you’re talking with, but give the interrupter a nod or say ‘I’ll be right with you John’ (or whoever). As soon as you’re free, say ‘now, John, what can I do for you?’ After a few times, they’ll generally stop jostling for position, because they come to trust that they’ll get their turn. Of course, there are often inter-band politics to deal with, and sometimes you’ll be caught in the crossfire of ego-contests. Experience teaches you how to deal with those, but if you stay calm, methodical and professional, you won’t go too far wrong.

Many artists and musicians are not good at describing what they need to hear, so you have to learn to decipher their requests, and again this comes with practice. Comments like ‘my voice feels muffled’ can often be addressed with mic technique and EQ (more about that next month), but simply being curious is the way to get clues – if you don’t understand what they’re getting at, ask open-ended questions. ‘Can you tell me more about what ‘crunchy/breathy/purple feels like?’ (Yes, people do come up with the oddest descriptions!) This has the added benefit of helping them to feel that you’re on their side and again, it builds trust. As a monitor engineer, your relationship with the band really is of prime importance – when they feel that you’ve got their back, they can relax and get on with their job of playing a great gig – and that’s what it’s all about!

Part 2 goes into detail about listening to different sounds within a mix, and how I approach EQ’ing individual inputs. In the meantime – get curious, keep listening, and have fun!
