The Mastering Show

You’ve probably heard of Eric Sarafin, aka Mixerman, but have you heard what he has to say about mastering ? As always it’s entertaining, potentially controversial but also thought-provoking, so it seemed like a good idea to get him on the show and ask him to explain himself ! We talk about: * Why he thinks if you don’t make money from your music, you shouldn’t pay for mastering * Whether an onlin...

This is huge - Apple have finally started using LUFS for their loudness normalisation, which means all the major streaming services now use the same method to measure loudness ! And perhaps more importantly, they’ve enable Sound Check by default on new devices. As always there are plenty of devilish details to be aware of though, so in this episode we talk in detail about this change, including: *...

In this episode we tackle one of the biggest challenges in modern mastering - the demand for super-loud masters in the dance & EDM genres. Our guest is Luca Pretolesi, and we talk to him in-depth about his approach to mastering for clubs & DJs. Luca’s masters are loud and we're always emphasising the value of balanced dynamics in mastering on this show, so you might think it would be an uncomforta...

Dolby Atmos has moved the goalposts for loudness, all the way down to -18 LUFS. This was one of the main topics of conversation for this year’s Dynamic Range Day, with the Atmos versions of 5 albums being nominated for the award - and in fact, the overall winner was an Atmos mix & master. In this episode I talk to Nick Rives from Capitol Studios, who mixed the winning album, and we discuss: *...

Apple’s announcement of Dolby Atmos support has caused an explosion of interest in the format - after all, it means almost any iOS user can stream immersive audio, even if they only have a pair of earbuds to listen on. But how does that even work? And for that matter, what is Dolby Atmos, and why should we care? And what about mastering for Atmos? Is it possible, or even necessary?  In t...

Time for another Q&A show! Thanks for all your comments, reviews and questions, please keep them coming. In this episode we tackle: * Are tools like SplitEQ fundamentally changing mastering? * Level automation - before or after the limiter? * Should you make separate masters for broadcast? * Can (and should) we correct absolute phase in mastering? * Do you need a dedicated headphone amp? * What ha...

What is non-linear processing, and why does it matter?  In this episode we dive deep into the topic with our guest Dan Worrall, and talk about: what non-linear processing is, why it can sound great and when it can sound terrible, and how to know the difference. Along the way, we also discuss  * Is reverb non-linear ? And why it’s confusing * How linear processing makes top-down mixing a good idea...

The Audio Engineering Society has just released new recommendations for the loudness levels streaming services should distribute their audio at - but they’re not for you and me. Having said that, understanding how they work is a powerful tool for predicting what will happen to your music when it's streamed. In this episode we talk about: * Who the TD1008 guidelines are for * Why they’re needed * H...

We round up a few different “loudness news” topics this episode, including: * Why Spotify have removed their limiter * But when they haven’t * And what it means for the way your music will sound * Plus, how the new loudness normalization options in Reaper might be useful for you * But why you need to be careful with them * What we think of Apple Music’s new lossless streaming feature * And more !...

People are interested in mastering for vinyl again - and stereo bass is a big problem, right? You should always mono it to avoid problems? Well actually, no. There are some challenges raised by a very wide stereo image on vinyl, especially in the bass, but as always it’s not as simple as it seems. In this episode we talk to our guest Ian Stewart in-depth about this issue, and dig into some of the...

It’s either the most powerful mastering technique known to man, or it isn’t really mastering at all, depending who you ask. Some people love it, others hate it, and some are mortally offended just by it’s name. Why does stem mastering provoke such passionate debate ? In this episode we dig into the topic to figure out the answers to these and other questions... * What is stem mastering ? * In fact...

It’s happening. Spotify are switching to using LUFS for their loudness normalization. If you’re thinking ‘I thought they already used it', that’s understandable - but they didn’t. They will in future though, and in this episode we talk about why the change matters, especially in the short-term. But also about when it doesn’t matter, and why it will hopefully matter even less as time goes on. Topic...

Let’s face it, LUFS don’t work. No-one understands them, when you set a load of different songs to -14 LUFS they all sound a different loudness, and they weren’t even developed using music. RMS is just better, right ? These are just some of the objections we’ve been hearing about LUFS recently, and in this episode we investigate them. Is there any truth to these claims and statements ? (Hint - Yes...

This is so good it just needed it’s own episode. It’s a groundbreaking, unique new way to make music online - and everyone should try it out ! It’s not just bleeps and beats, either - there are plenty of people using it to make fantastic acoustic and sample-based live-looping music as well. I’m talking about Endlesss, the new live-looping-jam-with-friends-online iOS app developed by musician Tim E...

Real-time remote audio work IS possible - with surprising quality and flexibility ! In this show I’ll describe techniques and strategies to help you mix, master, teach and even record remotely - and even suggest some ways to jam live. Kind of. Amongst other things I’ll describe how to: Stream lossless, low-latency audio to any DAW or browser, for up to 40 people Combine this audio stream with mult...

Our guest this episode is LA mastering engineer John Greenham who just won a Grammy for his work on Billie Eilish’s album. We talk to him about how he came to work with Billie, and dig into his work on the album in depth, discussing topics including: * John’s mastering chain and philosophy * Whether “Xanny” is the loudest song ever * How to get RMS levels above zero (!) * Loudness, confidence and...

We talk on this show about making a master sound great all the time - but what does that mean ? How can you tell the difference between a good or a great master, or whether you’re doing great work yourself, or not ? In this episode we discuss all these questions, plus: * Is it even possible to tell a good or a great master ? If not, why not ? * Is it about great sound, or great work ? * Why “great...

I often get asked if it’s possible to restore dynamics to a heavily limited, clipped or compressed source, to achieve a more dynamic master. The answer is… it’s complicated ! So in this episode we do our best to answer the question. Topics include: Why you shouldn’t do this When you might have to do this When doing this is a bad idea How to do it (the simple way, the complicated way and the really...

People are talking about minus 14 LUFS loudness more and more these days, but why ? What does this number mean, where does it come from, and why should you care ? In this episode we answer all these questions and more, including: * Which streaming services are using -14 LUFS * Why Spotify aren’t using -14 LUFS, and why it matters * Why you shouldn’t use minus 14 LUFS as a target (or any number) bu...

Time for another Q&A episode !

Can you make money from mastering ? And if so, how ? If you’re already charging people for your work, how can you be more effective and productive ? Our guest in this episode is Graham Cochrane from the Recording Revolution website, which has been so successful that he’s started helping other people use some of the same ideas and strategies to get them started making money in the audio business th...

There’s been lots of buzz and discussion about aliasing online recently, and lots of confusion, too. Is it a flaw in the whole idea of digital audio ? Does it explain why analogue modelling plugins can never sound exactly like the real thing ? Or is it just inaudible mathematical theorising ? In this episode we try to answer all these questions, plus Ian attempts to give an easy visual explanation...

Usually on the show we’re talking about mastering music for CD, download and streaming, but there’s another important final destination for the audio we work on - broadcast. And the difference with broadcast audio is - there are standards. Having said that, there often isn’t a dedicated mastering stage ! In this episode we dig into the whole fascinating topic with our guest Dallas Taylor from Defa...

Everything gets streamed these days, and almost all streaming platforms use lossy data encoding: mp3, AAC, OGG etc (OMG!) And these lossy codecs do a pretty remarkable result of preserving the quality, considering they strip out anywhere between 60-90% of the original data. But it’s not perfect - far from it ! In this show we talk about: * How your audio can be damaged by lossy data encoding * Why...

You might argue that reading about audio is like dancing about architecture. Or something. But you’d be wrong! In these days of podcasts and YouTube it’s easy to forget how many great books there are about audio, and what a fantastic resource they are for getting inspiration, ideas and learning new topics and techniques. in this show we share some of our favourites, including: * The book that took...
