REFERENCE - Everything You Need To Know
REFERENCE can help you get closer than ever to the sound of your favourite music. It does this by giving you the tools and insights you need to get your productions sounding more like your reference tracks.
The Wave Transport allows you to create multiple loops so you can quickly compare various sections of your track to your reference.
The powerful Level Match tool allows you to instantly and accurately match the loudness of your track and your references. This is crucial for a fair comparison.
The time-saving Auto Align button identifies if you have different versions of the same song and lines them up automatically, so you can seamlessly switch between them.
The visuals in the Trinity Display show you how your frequency balance, stereo width and compression compares to your reference track. You can also solo the frequency bands allowing you to zone in on the intricate differences between your mix and your references.
To get started, load an instance of REFERENCE on the master bus of your project. REFERENCE should go after your metering plugin, we recommend our comprehensive metering plugin LEVELS of course
Wave Transport and Tools
Add A Reference
To load a reference track, drag and drop your file into the Wave Transport, or click the ‘+’ icon. You can drag and drop multiple files onto the waveform if you have more than one reference track.
MIRROR / FREE
In the bottom right corner of the Wave Transport you will see the MIRROR and FREE buttons. MIRROR will match the playback location of your reference to your DAWs transport. This is useful for when you have a different version of the same track you’re working on and want to seamlessly jump between the versions at the same point in the song. When FREE is activated, you can navigate to any part of your reference track by clicking on the waveform in the Wave Transport.
You can create loops in FREE mode. To create a loop, select and drag over the part of the waveform you wish to loop. You can create as many loops as you want. To toggle a loop on and off ‘Ctrl+Click’ on the loop inside the Wave Transport. To remove all loops, ‘CMD+Click’ anywhere in the waveform section. Loops are not available in MIRROR mode.
In the top right corner of the Wave Transport you will see the Level Match button. When selected, this will accurately match the perceived loudness of the track you are working on and your reference. This is an absolutely crucial stage in comparing audio. Louder sounds give humans the illusion that they have a thicker bass and more clarity in the high frequencies. By level matching you’ll be able to compare the tracks fairly and make mixing decisions with confidence. Click the Level Match again to remove the level matching.
If you have multiple reference tracks, another button will appear adjacent to the Level Match button. This button, when clicked, will level match ALL of your reference tracks and the original track you're working on.
When you have different versions of the same mix or master, there can be slightly different lengths of silence at the beginning of the tracks. This can be really annoying and time consuming when you have to line them up to jump between them seamlessly during referencing. The Auto Align button does this laborious job for you in an instant so you can spend your time mixing.
When you load a new reference track, the Auto Align button will show that it’s ‘thinking’ by the two lines moving back and forth. If Auto Align detects that you have loaded a reference track that is a different version of the track you’re working on (i.e. an alternate mix or master) the Auto Align lines will stop moving and become clickable. When you click Auto Align, the selected reference will become aligned to the original track you are working on. If the reference track is not an alternate version of the track you’re working on the Auto Align button will show a cross.
If you have multiple versions of the same song, another button will appear adjacent to the Auto Align button . When selected, this button will automatically align any tracks that are an alternate version of the original track you are working on.
(note: Auto Align works best when you play the original in your DAW from the beginning)
The Track Tabs display what tracks you’ve loaded into REFERENCE. Add a reference file by dragging and dropping your file onto the Wave Transport, or by clicking the plus icon to the right of the Track Tabs. Click the minus icon to the right of the Track Tabs to remove the selected file from REFERENCE. You can toggle between your different references by clicking on the tabs. Double click on a Track Tab to change the label.
Original / Compare Buttons
The Original button is selected as default and you will hear the audio you are working on in your DAW. The REFERENCE button will enable playback of whichever reference track is selected in the Track Tabs. The buttons are linked so you don't have to move your mouse to switch from Original to Reference.
(Note: Left arrow key toggles between Original and Reference. change this to any key you like in settings)
Both the Original and REFERENCE buttons have adjacent meters giving you the peak, integrated LUFS and gain readings for the tracks you are comparing. Click on the readouts to reset the meters.
LUFS, PEAK, GAIN - Main readout
Click on the LUFS, PEAK or GAIN text to switch between the three different readouts for your original and reference track.
LUFS (loudness units relative to full scale) is an incredibly useful measurement as it gives you an accurate display of the perceived loudness of audio material.
PEAK will tell you the peak of your audio measured in dB (decibels).
GAIN will tell you how much gain you have increased or decreased your track by.
You can use the gain slider to adjust the gain of either the Original or REFERENCE track. The gain slider has a default range of -12dB to +12dB (can be increased to +-18dB in the settings). When using the Level Match feature, the gain of one of the tracks will be changed to match the other. You can see any gain increase or reduction on the gain slider and you can adjust the amount if necessary. To set the gain back to 0dB double click or ‘Alt+click’ on the slider.
When you listen to your reference track and you compare it to your own music, it can be difficult to put your finger on what changes you need to make. The one-of-a-kind Trinity Display uses intelligent algorithms to show you how the frequency balance, stereo width and punch of your track compares to your reference. You can create from 1 to 5 moveable frequency bands in the Trinity Display. Each band gives you a specific reading of how the punch and balance of your track compares to the punch and balance of your reference in the corresponding frequency band.
The Frequency Bands
The Trinity Display lets you analyse your music using from 1 to 5 frequency bands. To solo one of the frequency bands click anywhere inside the band. Click once more to un-solo that band and listen to the whole mix again. Soloing the bands is a great way to zone in on the intricate differences between your mix and your references.
To create a new frequency band divider, ‘Ctrl+click’ anywhere on the Trinity Display. Once a divider is created you can move it by clicking on it and dragging it. To remove a divider, ‘Ctrl+click’ on the divider itself.
The Stereo Spread displays the stereo width of both your original track and your reference. Each frequency band has it’s own Stereo Spread display allowing you to quickly identify which frequencies are wider or narrower. The two horizontal lines represent your Original track (the upper horizontal line) and your reference track (the lower horizontal line). Whichever you are monitoring will be highlighted white.
Understanding the stereo spread of both your original track and your reference will help you get closer to the sound you want. You can use panning in your DAW or a stereo tool to reduce or increase the width of a frequency band in your track.
The Trinity Display has a thin, faint white line through the middle. This represents 0dB. The white horizontal Level Line tells you how much perceived volume that frequency band has compared to the same frequency band in your reference track.
The white Level Line will move into the upper half of the Trinity Display if the frequency band has more perceived volume than the corresponding band in your reference. The Level Line will descend into the lower half of the Trinity Display if the frequency band has less perceived volume than the corresponding band in your reference.
Looking at the example below, we can determine that from 0-200Hz, our original track has less energy than our reference. This might prompt us to boost the volume of our bass, or add a low-frequency EQ boost to our kick. We can also see that from 200-2kHz our original track has a similar amount of perceived volume to our reference. So we might not change this at all. Finally, we can see that from 2kHz to 20kHz, our track has more perceived loudness than our reference. We might decide to musically reduce the high frequencies sticking out in our mix. Alternatively, we might decide that we like the clarity of our mix and leave the EQ balance as it is.
The purple Punch Dots in the Trinity Display will tell you how the short-term dynamic range of your track compares to the short-term dynamic range of your reference. The Punch Dots will move towards the white Level Line if that frequency band is more compressed in your original than in the corresponding frequency band of your reference. The Punch Dots will move away from the Level Line if that frequency band is less compressed in your original than in the corresponding frequency band of your reference. The more opaque the dots are the larger the difference between the punch of your track and the punch of the reference.
In the example below we can see that the low frequency band from 0-200Hz is showing the Punch Dots moving towards the Level Line. This tells us that our original track has more compression in the low frequencies than the reference track. This might prompt us to reduce the compression on our kick or bass elements. We can also see that from 200-2kHz the Punch Dots are barely visible. This means our original track has a similar amount of compression to our reference. Finally, we can see that from 2kHz to 20kHz, the Punch Dots are moving away from the Level Line. This means that the high frequencies are punchier in our track than in the reference. We may decide to compress these transients using a multi-band compressor, or we might decide that we actually like the punchy top end and leave it just as it is.
Changing The Scale
The Trinity Display has 4 different scales, +-5dB, +-10dB, +-15dB and +-20dB. By default the range will automatically change depending on the readings. To change the scale manually to a broader or more magnified setting, click the +/- numerical readouts at the bottom left or top left of the Trinity Display. If you are mastering a track and you want to visually see the intricate changes you have made then +-5dB would be the most magnified setting. Click the ‘A’ button to engage Automatic range setting.
Why The Trinity Display Works
Trying to get your mix or master to match the frequency spectrum of a reference track simply will not work. This is because there are so many variables that affect how a track sounds (such as instruments, tuning, performance, samples etc). The music won’t necessarily sound good even if your track and the reference look the same on the frequency spectrum. The Trinity Display has a unique approach to this…We use a modified version of LUFS calculations to identify how our ears perceive sonic differences between two tracks.
You can change the default settings of REFERENCE to suit your workflow. Click the (S) icon in the top right corner, choose your preferred defaults then click save.
Create Your Own Presets
Create and recall presets using the plugin wrapper in your DAW. When you create a preset you will be able to recall the reference tracks, the loops, the Level Match adjustments and the Trinity Display settings.
We recommend creating presets categorised by genres you work in. You can then quickly recall your favourite reference tracks with the loops already created.
