Welcome to Day 31 of 31 Days to Better Recordings.
For this final day of 31 Days to Better Recordings, I called in the big guns. This is a guest post by Ian Shepherd of the blogs Mastering Media and Production Advice. He is a professional mastering engineer in the UK.
Mastering is probably one of the most widely misunderstood aspects of audio production. So let’s start by getting this straight – what is mastering ? Well, here’s one answer:
And here’s another, more detailed attempt to answer the same question:
Great mastering can make all the difference to your music – as Tom Volpicelli said recently, it’s like finishing a painting – it isn’t ready to be viewed until it’s been framed.
Great mastering turns a collection of songs into an album – it balances songs against each other, creates a “line” through their sequence, paces and contrasts them perfectly – I like to think of it as finding their “centre of gravity”.
One of my favourite things is starting out with an album where you think – “this is almost perfect” to begin with – but after four or six hours of detailed listening and tweaking, the whole suddenly sounds far greater than the sum of the parts. Listening to each of the individual changes they might sound hardly any different, but as a whole, the effect is transformed.
On the other hand, there are plenty of projects where the difference is like night and day !
Now, I’ve been a professional mastering engineer for over fifteen years now, so it probably won’t come as a surprise to hear that if you want your music mastered, my best advice is – go to a full-time mastering engineer 🙂
So, why has Joe asked me to post here, then ?!?
Well, I’m also a realist, and I recognise that most of us with home studios simply don’t have the budget to get our music professionally mastered, and I’m passionate enough about what I do to hope that if people do decide to master their own material, they should do the best job they can, and at least avoid doing any damage without realising it. There’s a huge amount of poor advice out there, and I want to help put that right.
So, here are some suggestions to help you get the best out of mastering your own music. It’s too huge a subject to cover in one post, so I’m just going to throw some ideas out there with links to some posts with much more detail, if you’d like to read more:
Know What You’re Listening To
Mastering is very different from mixing, and ideally you need a whole different room and set of monitors to do it in. Obviously we can’t all have dedicated mastering studios though; it’s hard enough getting space for a home studio in the first place !
But if you have a decent hi-fi, how about using that, instead of the studio speakers ? It might sound insane, but one of the most important things about mastering is to know how things “should” sound when they’re right, and where better than in the place you normally listen to music ?
If that isn’t possible, the next best thing is – wherever you master – learn what music should sound like on them. Here’s post that tells you how – I wrote it about mixing, but it applies equally to mastering too:
If you ARE lucky enough to have a space to use just for mastering, here are some pointers on what makes a good mastering monitor:
Balance, Don’t Match
I see lots of talk about “matching” the sound in mastering, and even plugins designed to do it for you, but that misses the point. You don’t want all the songs to sound the same, you want them to sound “right” next to each other – you want the loud stuff to kick, and the soft stuff to sound gentle without getting lost – the bassy tunes to sound big and warm, and the aggressive guitar stuff to bite.
So, find the “centre of gravity” as I mentioned above, and then balance the songs around it – don’t try to match them all with each other.
Less is More
I’ve seen so many posts talking about mastering that suggest throwing the kitchen sink at it, but the truth is that at it’s core, mastering is just EQ, compression and limiting. So, use as little processing as you can to get the results you need. If a single-band EQ will do what you need, use that. If you can get away without extra compression, all the better.
Know your Sh*t
To get this minimalist approach right, you need to really understand EQ and compression – here are a couple of posts to get you thinking about this from a mastering perspective:
(This is written about mixing, but the hints and tips apply equally to mastering too)
And, again less is more – rather than chopping and changing EQ and compressors all the time, pick one of each that you like and take time to learn how to use them really well.
Don’t Become a Victim of the Loudness Wars
No post on mastering can avoid the loudness issue, and this one is no exception. The best advice I can give is here:
(Bear in mind that the suggested levels are for mixing, though – when mastering, a dynamic range of 8dB on the loudest moments can sound great)
And the key point is – keep it dynamic. Without quiet, there can be no loud.
If you really must squeeze every last ounce of level out of your tunes though, here’s my guide on how to do it without killing them stone dead:
Just remember – less is more ; )
Be Objective, Trust Your Instincts
One of the best things about having your music mastered by someone else is getting an objective, outside opinion. If you’ve performed, recorded and mixed your own music, the chances are you’re very close to it, and making good, clear decisions about it will be really hard – but you need to try !
So imagine you’re a mastering engineer, listening to the tunes for the first time. Work fast, be bold and trust your instincts. This is another reason mastering on a different system to your mixing rig can be a good idea – just to get a different perspective. It’s also a reason some people find it helpful to listen in the car and on earbuds, although this can be a two-edged sword – too many perspectives can be confusing !
Stand on the Shoulders of Giants
The chances are if you’re a musician or engineer you have idols – people whose work you love and aspire to copy. Well, find some reference points in mastering, too. Find some records you love, and play them alongside your own masters to get an idea how they should sound.
Use the TT Loudness Meter to avoid anything that’s too heavily compressed, though – and, be realistic. Choose something in a similar genre to what you’re working for, and think of the bigger picture – remember you’re not trying to match this stuff, just get in the right ballpark.
Day 31 Challenge
So, Joe has been setting challenges for you, so I will, too ! There are two stages:
Start thinking like a mastering engineer
Don’t try to actually do any mastering, right away – just start getting into the right place. Hit “shuffle” on your iPod and listen to a bunch of tunes and think about the mastering choices. How loud are they ? Do they have a balanced EQ ? Do they have a wide or narrow stereo image ? Most importantly, how do they sit next to other tracks on the album, or in your music collection ?
Start practising – on other people’s material
This is crucial – don’t use your own stuff ! Pick two or three tunes you think will work well together but don’t sound right yet as a group, and imagine you’re releasing them as an EP. Pick the one you like the sound of most, and adjust it’s level so it’s not too loud – tweak the EQ if necessary. Then try balancing the other tracks against each other, using as little processing as possible. Just enough, but not too much.
This is an invaluable exercise, and will soon get you focusing on the things that really count. Using other people’s tunes will give you the perspective you need – all you need to do now is apply it to your own music !
