PROCESS. AUDIO SUGAR
This one-stop enhancement plugin packs an arsenal of behind-thescenes effects into a deceptively straightforward interface
The debut plugin from the newly formed software division of audio training providers pureMix is a ‘sweetening’ effect (geddit?) for use on mixes, busses and individual instruments. Sugar ‘intelligently’ applies compression, EQ transient shaping and other processes across four frequency bands, with no user-accessible parameters for them beyond the amount brought to bear.
Pour some Sugar
Each of Sugar’s four bands (Low, Medium, High and Air) offers two different processing modes – see Put your bands together – a Bypass button, and, in the default Stereo setup, a fader for ramping up the effect. In Mid/Side configuration, the last becomes a pair of faders for Mid and Side. Simply raise the fader for the band (or its M/S channel) you want to enhance until you like what you hear, flipping between the colours for two different vibes. The process is entirely additive, and the big Wet Inject knob in the middle raises and lowers all four bands together. This is an eye-candy alternative to a band link button, really, but it’s certainly convenient as a global ‘more/less processing’ control.
The FX Only button lets you hear the wet signal in isolation, while activating Level Management compensates for level changes by automatically moving the Output Gain slider up and down. The spectrum analyser, meanwhile, visualises the effect in terms of input and output levels across the frequency range.
The band crossovers are linear phase, but this can be defeated when minimal latency is required or if you just prefer the (noticeably different, especially in the higher frequencies) sound without. The crossover frequencies are fixed depending on the mode selected for each band, and while we understand the thinking here – that their positioning is intrinsic to the tuning of the processes – the ability to move them would be welcome nonetheless, even if only for creative experimentation.
Any excesses at the top and bottom can be reined in using the onboard High- and Low-pass filters, which are switchable between 12dB and 48dB/octave roll-off, with cutoff frequencies ranging from 10Hz to 22kHz. The filters also follow the linear phase setting, changing to an IIR minimum phase algorithm when it’s disabled.
Finally, at the very end of the signal path, the Saturation module offers three increasingly strong styles of audio punishment: Drive, Distort and Crush. Once the amount of saturation dialled gets past about 40%, even Drive is anything but subtle, so this particular component needs to be handled with care.
Sweet treat
Sugar does exactly what it sets out to: making stuff sound more present, focused, coherent, saturated and powerful via a minimal set of controls. The Air band, in particular, is pure magic in its lifting effect, and it’s always worth trying both modes for every band, as the differences between them can be profound. We find it most effective on busses and mixes – partly due to the unadjustable crossovers, and partly because of the fairly high CPU usage.
With the caveat that it could easily do more harm than good if deployed without the guidance of a well-trained ear, we can heartily recommend Sugar as a beautifully calibrated and sonically impressive multiband enhancer for mixing and mastering.
