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 difference between saturation and distortion
* …and how to use them creatively
* The difference between a perfect 5th and a power chord
* ...and how to play chords on a trombone

The Mastering Show #79 - Dan Worrall on non-linear processing

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 uncomfortable conversation... or you might be surprised.

Some of the topics we cover include:

 * Why do DJs demand loud masters for club playback ?
 * Luca’s strategy to deliver this without sacrificing dynamics for streaming
 * Hint - it’s NOT all about limiting and compression
 * How loud Luca's masters are (which may not be quite as loud as you think)
 * The club genres that DON’T demand extreme loudness
 * Where things might go in future

The Mastering Show #83 - Mastering for clubs & DJs with Luca Pretolesi

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:

 * Why it’s so important
 * How much music online is REALLY normalised anyway ?
 * Why the answer is surprising to many musicians and engineers
 * Why Apple finally made this change
 * A few quirks and gotchas
 * Why it’s good news
 * And what to do about it (and what NOT to do!)

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 online mastering service is actually a better option for a musician starting out (gasp)
 * Eric's favourite limiter, how he uses it and why
 * How loud he makes his mixes
 * Recent potentially game-changing developments...
 * And why they might make mastering engineers obsolete !

The Mastering Show Podcast #85 - Mixerman versus Mastering

As mastering plugins become more sophisticated and more technical, there’s an interesting trend towards making the interfaces… less so. 

As well as traditional technical terms and numbered scales, controls labelled with less technical terms like “warmth”, “bite” and “colour” are becoming more common. And some interfaces are just… bizarre ! 

Is that good ? Or not ? In this episode Jon and I like at some more unconventional plugin user interface designs, and discuss:

    Why technical interfaces can be a problem
    When a more creative approach can be a good thing...
    …and when it’s not
    Some of our favourite ‘unconventional' plugin designs
    But are they better than just closing our eyes ?!
    Should plugins emulate the design of the hardware
    And does it make them sound better ?!?

The Mastering Show Podcast #86 - Mastering plugins - technical versus creative

It’s amazing what mastering can achieve - but it’s also amazing how many things can influence the results we get right from the recording stage.

In this episode Ian talks to Mike Senior about how to fix mastering problems at the recording stage, without using a time machine ! Topics include how to avoid:

    Muddy mids
    Harsh guitars
    Sibilance
    Resonant snares
    Boomy or hollow vocals
    Exposed vocals
    Stereo image issues

And many more !

The Mastering Show Podcast #87 - Fix mastering problems - in the recording !

DJs get a lot of flak, especially about loudness. There’s a deep-seated belief that “loud” masters are still a requirement for club music, and that DJs are somehow to blame. 

But is this fair ? The reality is much more complicated and interesting than the popular cliche that DJs will only play loud masters, and in this episode Ian dives deep into the issue with Joe Caithness, who works as both a DJ and a mastering engineer. Topics include:

    The reality of DJ-ing
    The problem with peaks
    Loudness ? Or consistency ?
    The power of Pioneer
    The shocking missed opportunity of loudness metadata
    The ‘sound’ of loudness

And much more !

The Mastering Show EP #88 - Do DJs REALLY want loud masters ?

If you’re not already listening to Matt Boudreau’s fantastic podcast Working Class Audio, you need to start now !

Matt is a highly respected mixing and mastering engineer who has recently moved into working in Dolby Atmos, where he’s already picked up some seriously impressive credits - oh, and also produces one of the top Audio podcasts around.

Which is why if I try to think of anyone better to learn the fundamentals of good audio for podcasting and journalism from… well, I can’t. And the great news is that Matt has put together a new “PodClass” course to help people with just that.

In this episode we talk about the course and what inspired it, but also plenty of other great stuff, including

    Making the move from pro musician to audio engineer
    Getting started in Atmos - workflow, dynamics and more
    Work-Life balance - is it better to be a lark, or a night-owl ?
    The secret advantages of running your own podcast...
    …and the crucial importance of great audio (And what it has to do with COVID lockdowns !)

The Mastering Show #89 - Sonic Fundamentals for Podcasters with Matt Boudreau

Everyone is talking about inter-sample peaks and True Peak limiters - or in fact it’s more accurate to say they’re arguing about whether ISPs are audible or not, and whether True Peak limiters sound bad !

In this episode I’m joined by Alexey Lukin, iZotope’s “godfather of RX”, to talk in detail about exactly what ISPs are and why they’re so confusing - including:

 * How are inter-sample peaks measured, and why do you see different results with different meters ?
 * What are DSP overshoot peaks, and how are they different ?
 * What does over-sampling have to do with all this, and why is it important ?
 * Do True Peak limiters really sound bad, and how should we test them ?
 * Why will they NOT prevent lossy decoder clipping, sometimes ? And
 * What the hell are we supposed to do about all this ?!?

The Mastering Show #90 - Inter-sample peaks and True Peak limiting - the devilish details

It’s virtually impossible that you haven’t heard music of some kind mixed by Alan Meyerson by this point - he’s one of the most prolific and successful film score mixers in the business.

And luckily for us, he’s also super-generous and open about the information he shares, including his perspectives on mixing and ‘mastering’ music for the movies. So in this episode we dig deep into all the details, including topics like:
* Is there really such a thing as ‘mastering’ for film ?
* What needs to be delivered, and what is the process ?
* How loud does it need to be - are there any standards ?
* When does Alan deliver mixes in Atmos, and why ?
* How he uses the centre channel and surround channels
* Why you might want to use saturation or pitch-shifting (!) in a movie score mix

The Mastering Show # 91 - Mixing and mastering music for the movies with Alan Meyerson

You can't go a day without someone telling you how loud your music should be, these days.

"Everything has to be -8 LUFS"
"EDM has to be -6 LUFS or louder"
"-11 is the perfect balance"
"Just master everything to -14"

...but they can't all be right !

In fact, none of them are, and even more importantly, they may not even be talking about the same thing. And the differences are really important. So in this episode I try explain really clearly and concisely:

    The 3 different types of LUFS
    The difference between them
    Why it’s crucial to know which type you’re talking about
    Why mastering to integrated targets makes no sense
    When -14 LUFS isn’t loud enough – and why ?
    Why it’s not about ‘how loud’, it’s about how you make it loud
    Why integrated LUFS values are the result, not the goal of mastering

The Mastering Show Podcast #92 - These are not the LUFS you are looking for

I’m always arguing for balanced dynamics rather than loudness for it’s own sake, but some people have a different opinion - high loudness is important, and even beneficial.

Nick Di Lorenzo is one of them - he says that loudness is important regularly on his YouTube channel. So in this episode I invited him on to explore that idea in more detail, and really get into the nuances of the topic. Do you need to be mastering loud ? Topics include:
* The practicalities of loudness
* What makes things sound loud anyway ?
* Record labels versus loudness
* Why loudness IS important
* Why LUFS don’t matter, and
* The difference between loudness and LUFS

The Mastering Show #93 - Do you NEED to be mastering loud ?

People are always asking me about mastering for vinyl, and I’m happy to try and help based on the experience I have. I don’t actually cut vinyl myself though, so that advice is always limited and second-hand. 

So for this episode I decided to talk to a genuine expert on the topic - Scott Hull from Masterdisk - and really get into the details. 

Scott’s knowledge and experience of cutting vinyl is enormous, as you’ll hear, and I took full advantage of that in this episode ! Some of the things we talked about include:

    The 4 stages of vinyl production, and why each is important
    How making assumptions about vinyl mastering can backfire
    Why choosing which plant is going to press the records is crucial
    The crucial role of the lathe - and it’s setup
    The myth of duration on vinyl - why “20 minutes per side” isn’t a hard and fast rule
    Why less limiting allows you to cut louder on vinyl
    What is the magic of vinyl ?

The Mastering Show Podcast #94 -The truth about vinyl (with Scott Hull)

The Billboard Top 50 global singles from the first half of 2024 have an average loudness of -8.3 LUFS

So that’s how loud we should be making our masters, right ?

Well…

It certainly might seem that way, but in reality it’s a bit more complicated than that. This is only one of the interesting results that Ian Stewart presented in his latest blog post for iZoTope, and in this episode I asked him back on to really dig into some of the details and nuance.

Plus I also wanted to talk to him about the amazing plug-in that got invented during the last episode he was on ! (Well, that’s my story and I’m sticking to it 😛)

During the show we talk about:

 * What that -8 LUFS average result REALLY means, and how much attention you should pay to it
 * Who the most successful artist in the Top 50 is, and the loudness statistics of their music
 * The problem with the title iZotope chose for the post
 * All the other results, trends and biases in the data
 * Basslane Pro, the plug-in Ian worked with Tone Projects to develop, why it’s unique - and how The Mastering Show helped it happen !

The Mastering Show Podcast #95 - Loudness trends in 2024: should you follow them ? with Ian Stewart

We’ve been using “soft clipping" in mastering for over 20 years at this point, but it suddenly feels as if it’s all anyone is talking about ! New plugins, new suggestions about how to use it, and wild new claims about how amazing it sounds. 

Except it doesn’t.

At least – not all the time, and not for all material.

In this episode Joe Caithness and I dig deep into the details and talk about:

* What clipping is, and what it isn’t
* The crucial differences between hard and soft clipping
* What makes a great clipping plugin (and why comparing them is a nightmare)
* Some of our favourite clipping plugins and how we use them
* The kinds of material that work best with clipping, and what type to use
* The golden rule to follow if you want to experiment with clipping yourself

The Mastering Show Podcast #96 - Flippin' Clippin' !

The term “legend” gets thrown all the time in audio production circles, but my guest this episode really deserves it. 

I’m sure you already know this but Ken Scott has worked with the Beatles, David Bowie, Elton John and Supertramp amongst so many others, so I was delighted when he agreed to join me for this episode !

There were so many things we could have talked about it was hard to know where to start, but here are just a few of the topics we covered:
* Why Abbey Road trained their engineers in mastering before they were ever allowed to engineer a recording session
* The value of mentors - and being thrown in at the deep end
* Mixing in sections (instead of using automation)
* When limited resources are a Good Thing
* Re-mixing Ziggy Stardust in Dolby Atmos (with added drum samples…!)
* …and how the new mix translates to stereo
