Loudness Processing Examples: Here are examples of some of the different processes you might use to match the loudness of your mixes to commercial reference tracks. This mix ( Ex19.01: WAV/MP3 play_arrow ) has a lot of detail in it, and also some deliberate buss compression ‘pumping’, but no loudness-enhancement processing. Now listen to these loudness-enhanced versions: with ‘top-down’ squeeze (full-band Ex19.02: WAV/MP3 play_arrow ; multi-band Ex19.03: WAV/MP3 play_arrow ); with ‘bottom-up’ squeeze (full-band Ex19.04: WAV/MP3 play_arrow ; multi-band Ex19.05: WAV/MP3 play_arrow ); with limiting (full-band Ex19.06: WAV/MP3 play_arrow ; multi-band Ex19.07: WAV/MP3 play_arrow ); with subtle multi-band distortion ( Ex19.08: WAV/MP3 play_arrow ); with digital clipping ( Ex19.09: WAV/MP3 play_arrow ). Note that the digital peak level for all these files is identical (-0.3dBFS), so any subjective loudness differences are independent of peak level. To assess the undesirable side-effects of these loudness-enhancement processes most effectively, line up the WAV files in your DAW system and then make sure to match their subjective loudnesses (by adjusting the channel faders) before switching between them.
Automation For Long-term Mix Dynamics: To demonstrate the need for automation to adjust effects levels between sections, listen first to this dry mix ( Ex19.10: WAV/MP3 play_arrow ). Applying effects levels suitable for the more thickly textured chorus section leaves the preceding verse sounding swamped ( Ex19.11: WAV/MP3 play_arrow ), whereas reducing the effects levels for the verse using automation ( Ex19.12: WAV/MP3 play_arrow ) means that the verse sounds closer, therefore demanding more attention, while the chorus can then arrive with more authority by virtue of sounding more expansive.
Creating Build-up With Arrangement Techniques: Mix Rescue May 2010 featured an unusually long build-up during its outro section. For the remix, much of this build-up was created using a progressively more complex guitar arrangement, which I’ve isolated in this file ( Ex19.13: WAV/MP3 play_arrow ). Now that you’ve heard it on its own, check out how it works in the context of the completed remix ( Ex19.14: WAV/MP3 play_arrow ).
Intelligent Trouble-shooting With Automation: This acoustic guitar part has over-prominent fret noise ( Ex19.15: WAV/MP3 play_arrow ), which can be remedied surprisingly effectively with an automated EQ band ( Ex19.16: WAV/MP3 play_arrow ). This one, on the other hand, has sporadic soundhole ‘boom’ ( Ex19.17: WAV/MP3 play_arrow ), and this unevenness can be dealt with using automated EQ notches ( Ex19.18: WAV/MP3 play_arrow ).
Perfecting The Mix Balance With Automation: The foremost use of automation for fine balancing has got to be in relation to lead vocals, in order to maximise intelligibility. To understand what this means in practice, compare this mix without detailed vocal rides ( Ex19.19: WAV/MP3 play_arrow ) with this version where the vocal level has been automated extensively ( Ex19.20: WAV/MP3 play_arrow ) – it’s not as consistently upfront-sounding, despite heavy compression, because the processing isn’t intelligent enough to judge how audible the vocal needs to be within the context of the mix. It’s also not uncommon for dynamic tonal changes to creep into vocal recordings (for example if the singer moves relative to the microphone while performing), and in vocal-led mixes both fader and EQ automation may therefore be called for. In Mix Rescue February 2012, for instance, in addition to my usual fader rides I also automated the gain control of a very broad high-frequency peaking filter centred at 7.6kHz to really lock the vocals subjective position in the balance. Here’s a section of that final mix with the fader and EQ automation active ( Ex19.35: WAV/MP3 play_arrow ) and with both bypassed ( Ex19.36: WAV/MP3 play_arrow ). The effect of just the EQ rides can be heard in isolation in the following lead-vocal examples from Mix Rescue November 2011 (with EQ automation Ex19.37: WAV/MP3 play_arrow ; without EQ automation Ex19.38: WAV/MP3 play_arrow ). Vocal effects levels are also often automated both for balance and to make an artistic statement. Mix Rescue January 2010 features a good middle-of-the-road example of this kind of automation. This is the isolated lead vocal, complete with its automated send effects ( Ex19.21: WAV/MP3 play_arrow ), and here’s the effects returns on their own ( Ex19.22: WAV/MP3 play_arrow ) so you can hear the automation more clearly. Now listen to how these effects rides work within the context of the final remix ( Ex19.23: WAV/MP3 play_arrow ). Mix Rescue March 2010 features a more extreme special-effect application, where automated delay ( Ex19.24: WAV/MP3 play_arrow ) and reverb ( Ex19.25: WAV/MP3 play_arrow ) create an arresting combination. Although vocals often claim the lion’s share of detailed rides, other instruments do also benefit from them. For example, here’s a practical demonstration of the Andy Wallace-inspired cymbal rides mentioned in the book (without automation Ex19.26: WAV/MP3 play_arrow ; with automation Ex19.27: WAV/MP3 play_arrow ).
Mix Revisions: Mix Rescue May 2010 illustrates how a client’s rejection of your first mix can help provide the information you need to deliver a more acceptable second version. In this case, although the first version ( Ex19.28: WAV/MP3 play_arrow ) wasn’t ‘wrong’ from a technical standpoint, it was at odds with the artist’s own sonic ideals. Discussing what was wrong with this version clarified the brief significantly, and the second version ( Ex19.29: WAV/MP3 play_arrow ) met with the artist’s approval. A more extended example of this revision/feedback process can be found in Mix Rescue February 2010, where the harp part went through five different versions ( Ex19.30: WAV/MP3 play_arrow ; Ex19.31: WAV/MP3 play_arrow ; Ex19.32: WAV/MP3 play_arrow ; Ex19.33: WAV/MP3 play_arrow ; Ex19.34: WAV/MP3 play_arrow ) before it hit the mark!
- Affordable Plug-ins For Mastering-style Loudness Matching: I’ve already mentioned masses of plug-in contenders in the other resources pages, but my own personal freeware favourites are Georg Yohng W1 Limiter; GVST GClip; Venn Audio Free Clip; LVC Audio ClipShifter and Limited-Z; Sonic Anomaly Unlimited; and and Vladgsound Limiter No.6. A couple of affordable payware options I also use a lot are IK Multimedia’s (particularly its ‘Advanced 1’ and ‘Clean’ algorithms) and Toneboosters TB Barricade. Another bit of affordable software I find very useful for comparing mix tonalities is Harbal.
Celebrated Buss Compressors: This ‘Classic Compressors’ article lists a good number of the most celebrated buss compressors, and provides a reference point when selecting suitable master-buss plug-ins for your own mix work, especially if you have access to a library of digitally emulated classic compressors.
The ‘Loudness War’ Debate: Here are a few good sites if you’re interested in the so-called ‘Loudness War‘: Turn Me Up, Pleasurize Music Foundation. For some thought-provoking in-depth exploration of this topic, check out the following articles: ‘Is Loud Music Better?’, ‘Dynamic Range & The Loudness War’, and ‘The End Of The Loudness War?’
What To Expect From Mastering: It’s my opinion that most small-studio mix engineers expect too much from mastering, a point which I felt was well illustrated in Sound On Sound’s Online Mastering Services Shootout, with its follow-up Online Mastering Blind Test Results and SOS forum polls (SOS Forum poll 1, SOS Forum poll 2, SOS Forum poll 3). Mix Rescue August 2015 also provides a good perspective on what mastering’s really about, especially as far as project-studio productions are concerned.
Demo-chasing & Mix Revisions: In Mix Rescue July 2010 I provide some advice on ‘chasing the demo’ at mixdown, and here some other Mix Rescues where I talk about dealing with mix revision requests Mix Rescue February 2010, Mix Rescue May 2010, and Mix Rescue July 2008.
