Taming Vocals Without Compression

During any given session, there is a good chance you will experience times where the artist gets really quiet, and parts when they get really loud. While dynamics are good to have in a song, having too much can hinder the mix and result in parts getting lost, or parts being too loud. Often times when this situation arises,  new engineers slap a compressor on the channel to tame some of the peaks and bring up some of the quiet parts. However, more times than not, this can do more harm than good because it doesn’t work for all the parts on the channel.  I’m going to show you a way to fix this problem without relaying solely on compression to do it for you.

When recording vocals, it’s common for the vocalist to move around , whisper, sing, rap, yell, all within the same take. If you are constantly getting overly dynamic recordings from quiet to loud to clipping, first take the time address it at the source. Start by giving your client a heads up to try and stay within a certain distance from the microphone for the best quality. If you mention that it will have a better result, chances are they will have no problem trying to keep their distance in check. Now, of course they still will move around, and things will still sound overly dynamic, but if it’s even 10% better than before, it helps.

Secondly, check the settings on your preamp. Most preamps have a built in compressor in them. “But wait, I thought you said taming without compression!”. Well compression on the front end before being converted into your DAW, not only becomes part of the recording chain before mixing, but can avoid clipping, and work wonders when it comes time to mix the song. Use compression at the source, not when it’s too late. 

Here at Studio 11, we have 2 main preamps that we use for vocals. The Manley Vox Box, and the Drawmer 1969 Mercenary Edition tube-preamp. Both have compressors built into them, and as a result become an integral part of the front end chain. If your preamp doesn’t have a compressor on it, look into putting one in your chain (but be careful to get one without too much coloration or you can do more harm than good). However if you do have a compressor, a gentle ratio, a fast attack with a few dB of gain reduction can work wonders. The fast attack will grab those loud transients to avoid clipping, tame some of the mid sized transients, and boost up of the quiet parts. If all is done correctly, you will end up with a hotter signal for your A/D converter (hotter the better for conversion), and a more solid, thicker looking waveform. But there will still be parts that are too quiet. As I mentioned before, the easy (and lazy fix) is to slap a compressor on there to bring out some of those softer parts. The problem with doing this is that it may work for some of the sound,  but when there are very loud parts, its going to sound very audibly compressed and lifeless (which you don’t want).  It’s a good rule of thumb to try to always use compression as a tool, not an effect. In most cases compression should be mostly translucent and shouldn’t take you away from the performance of the vocals. Of course there are some cases where over compressing can be used as an effect (think “All In” setting on the Universal Audio 1176), but most cases subtlety is best.

So instead of jumping right to the compressor, bring out that simple Gain plug in that you forgot existed the Audiosuite in Pro Tools. (or if your in Ableton Live, break the clip, and adjust volume of the section manually). Go through the track , using your ears and looking at the size of the waveforms, bring up those quieter parts so that they are on the same level as the rest. Now of course I’m not saying that the entire vocal track should be equally as loud, because that would be boring and dynamicless, but put them on a similar volume plane so they are always audible.  Keep in mind there will be parts that are supposed to be quieter ( think intros, bridges, outros ), but the parts that are in the middle of phrases , i.e words that were sung quietly when they moved their head from the mic, or maybe a word that was much louder than the other parts, can be gained up or down accordingly. 

If you prefer using a smoother analogous volume adjustment (instead of gaining sections), reach for that volume automation. Riding the volume to level out quiet parts can lead to a very rewarding result in the end, and will certainly be better than slapping a compressor to “fix” those spots. Once you fixed everything and everything is leveled out and audible, then you can put a compressor  with a gentle ratio to glue it even further (if you even need to), or to bring out quiet transients that you couldn’t access via that gain tool or automation. Following these steps will help your vocals feel more present in the mix, and will avoid that dreadful “overcompressed” sound that you hear so often. Just try it out, play around with the front end compression, gain, and volume automation and you’ll be well on your way to taming those vocals , without sucking the life out of them.

How To Make Your Digital Tracks Sound Analog… Using Digital

Let’s face it, with the convenience and quality of modern DAWS , plug ins, and virtual instruments, it’s hard to justify spending a fortune on physical analog gear. Digital (computer) processing has become so good that using the right plug ins and techniques, can yield a surprising (and convincing) analog sound . I’m going to show you just a few ways to bring the pleasing qualities of analog in that sterile digital recording.  


 

Adding Warmth: Analog Modeling plug-ins, EQ, De-essing

One way to add warmth to your digital sounds is running them through some analog modeling plug ins. Instead of grabbing that stock Pro Tools compressor, try using plug ins like the CLA2A from Waves (modeled after the infamous LA2A compressor), or the SSL bus compressor. You’ll find these compressors will react a little differently than a stock digital compressor, and tend to have more coloration, more natural saturation, and a bit more noise (all characteristic of analog) to add to the signal. For EQ, Waves also offers an API parametric EQ modeled after the modules in their analog consoles that sound great. Actual analog EQ will add harmonic distortion (more on this later) simply because they are slightly non linear, where digital EQ can introduce harmonics not related to the fundamental which sound unnatural when pushed hard.  But you’ll notice when using the digital versions of the EQ, in particular the API EQ, that they took the non linear harmonic distortion of the actual unit into consideration when designing it, and as a result more closely resembles an “analog” sound. Another simple way to warm up a track is by subtractively EQing some high end content . Rolling off, or reducing some unwanted highs (specifically the harsh 4khz -8khz range), can add a smoothness to your track that analog processing naturally gives. Also , experiment with de-essing things other than vocals such as cymbals, guitars (renaissance de-esser works great) to have a similar smoothing effect. Take some time, learn the characteristics of each plug in. You will be able to utilize and control them much more when you do.

Adding Harmonics: Harmonic Distortion, Emulated Tape Saturation

A common problem with digital sounds , is that they sometimes lack harmonics that analog naturally adds from it’s physical circuity. Even simply running a sound through an analog console will add pleasing harmonics related to the fundamental pitch by the time it reaches the end of the circuit. There are a couple ways to add harmonics to a track in the digital domain. A go to plug in I use to add a bit of harmonics or grit is the Lo Fi by Waves. Even with just a small amount of the saturation or distortion or bit/sample rate reduction , you can introduce new harmonics to give the sound a ton more analog character. Another favorite of mine is the Kramer Tape emulation. Achieving a similar sound as the Lo Fi, in a slightly different way (tape compression, instead of bit and sample rate reduction), you can add tons of warm harmonics that a real tape machine would reproduce. Adding harmonics in this way can also be referred to as adding distortion to the signal. Some people think of distortion as a negative thing in audio (especially in the digital domain), but when used subtly can not only make the sound more rich and pleasing to the ears, but it can increase the subjective loudness of it as well (by shifting the perceived frequencies closer to our sensitive hearing range). …So if you want to make your mixes appear louder…hint hint.

Increasing Noise: Raising the Noisefloor

In a modern digital system the noisefloor is pretty much close to complete silence. This can be looked at as a good thing if you want crystal clean sounds, but one of the pleasing qualities of analog is that it is not clean but in fact a little dirty. So bring up a sample or generate a sound of white noise, vinyl noise, or background hum, and put it in the background of the song so that it is just barely audible. The way I usually add noise is through a free plug in by iZotope called Vinyl. Just put vinyl on a separate track (so you can have better control over it), increase the “mechanical noise”, roll off some of the low frequencies with an EQ, and have it sit quietly in the background. Aside from the noise sounding aesthetically pleasing, and adding to the overall harmonic content of a song (increasing subjective fullness), it also fills in gaps of a song that cut out to silence (drops, breaks). Hearing complete silence in a digital domain really just tends to sound strange to our ears, especially after or before a full spectrum of sound. This weirdness is most noticed on headphones  where your ears are blocked off from outside noise (giving the impression that for a split second you think your wearing ear plugs!) We like a noise floor and hear it every second of every day. It not only adds an analog quality,  but it also adds a very desirable human element.


 

These are the basics of how to make your digital tracks sound more analog using digital plug ins. There are even more things you can do (adding tape wow and flutter in some cases for example), but these are good starting points to bring a little more analog flavor into your digital tracks. Play around with the different combinations, listen to analog recordings, and try to mimic them, you’ll find that you had the tools to do it this whole time.
