How to use bitcrushing to add brightness

Just a little crush

Modern digital production has ushered in an era of extreme sonic brightness that producers of yesteryear couldn’t possibly have imagined. Part of this is down to the increased fidelity and dynamic range of modern equipment, coupled with the tools to boost frequencies with far more precision and power than ever before.

The other reason is sonic one-upmanship, whereby as one track gets brighter, the next has to at least match it or risk sounding dull by comparison. The effect on the industry has been a veritable snowballing of top end as each track is mixed to stand out from the crowd, and making the track brighter is an easy and obvious way to achieve this. And in an era where more people are mixing more tunes for release, with more powerful tools than ever before, some of the more subtle craft of the best mixing engineers has been shouted down.

But among those at the top end of the profession there is the realisation that brightness can be taken too far, and that you can’t just make every part in a mix brighter without making the overall mix much more harsh. Fortunately, there are various other ways to give a channel that sonic edge that cuts through a mix but which don’t necessarily add huge amounts of bright and harsh top end.

One of the oldest, and the best, is our old friend distortion, which is of course most commonly associated with guitar parts. The distinct harmonics of distortion give these sounds an edge (subtle or obvious) that sets them apart from others - and in this age of technological marvels, digital bitcrushers can impart a similar edge without producing that tell-tale thrasher sound. Let’s have a look at the best ways of getting this done…

For a comprehensive selection of effects tutorials and techniques, check out Computer Music Special: Effects (issue 47) which is on sale now.

Stand out performers

Step 1: We have a simple mix, and we want to get our guitar and vocal to stand out a little more without brightening them too much. We turn to our guitar first, leaving the vocal until last – as we want the vocal to cut through everything, we need to know how the guitar will sound first.

Overdrive

Step 2: Next we add an overdrive effect to our guitar. We don’t want it to be very strong, as we aren’t after a distorted metal-style sound. Other options here would include valve-style overdrive effects, whether as standalone plug-ins or included in another plug-in, such as preamp or EQ. These can also add a nice harmonic edge.

Bringing the bite

Step 3: Now we simply tweak the overdrive signal until it adds a little subtle bite, allowing the guitar to retain most of its original character but with enough edge that it makes its presence in the mix known. We might also consider adding a tape-emulating plug-in at this point to remove any digital harshness that may have crept in.

The vocal

Step 4: Now we turn our attention to the vocal, and for that we’re adding the free plug-in, TAL-Bitcrusher from Togu Audio Line. The default setting is almost what we’re after - it’s just a little bit too strong, so we pull down the dry/wet balance, allowing just enough wet signal to make the vocal stand out.

White noise

Step 5: There is also a white noise generator on TAL-Bitcrusher, which is another useful tool to give edge to a sound, but on this vocal channel we will use very little (if any) as it doesn’t sound as natural. On a snare or other percussive sound, on the other hand, we’d probably use much more.
