Vocals are often one of the most important elements in a song, regardless of genre. So, it’s safe to say that how you approach mixing vocals can make or break your track. Have you ever heard a hit record, or even just a really good song, with a poorly mixed singer? Probably not…and it’s especially uncommon with the pristine pop vocals we’re accustomed to in modern music.
Mixing vocals can be tricky, even when you’re working with a well recorded, talented artist. The following tips are a great place to start in order to achieve better, more professional sounding vocals.
We’re all familiar with basic compression and EQ, but how often do you consider saturation when mixing a vocal track?
When we use the term “saturation,” we’re referring to plugins that emulate what analogue equipment used to do to a recording. Saturation adds rich harmonics/overtones and a bit of distortion to make a vocal “fatter” and more exciting for listeners. It can help push a performance to the front for an “in-your-face” sound.
Experiment with saturation to give a vocal more edge, helping it stand out in a dense mix. Lo-Fi, included with Pro Tools, is just one example of these types of plugins that can enhance an otherwise dry/dull vocal.
For those who are new to mixing, compression can be a rather mysterious signal processor. On paper, it’s easy enough to understand that a compressor smooths out a performance by bringing peaks down and valleys up. However, it’s sometimes difficult to determine its effects for ears that are unaccustomed to it.
If you find yourself struggling with vocal compression, the following is an excellent starting point to orientate yourself.
Set a ratio of 4:1; set the attack time to medium or fast; adjust for a medium release time; and adjust the threshold for about 4-6 dB of gain reduction.
These rules aren’t hard and fast, so use your judgement and compress to taste! What works for one track may not work for another, and so on, but these guidelines are a wonderful place to start.
3. “Magic” Frequencies for Mixing Vocals
Akin to the compression starting points outlined above, knowing specific frequencies and how they effect vocals means you can make quick, precise adjustments with less guesswork. Check out these five areas of interest for vocal EQ:
- 120 Hz: Fullness
- 240 Hz: Boominess
- 5 kHz: Presence
- 4 to 7 kHz: Sibilance
- 10 to 15 kHz: Air
Experiment with each of these frequencies or bands and see how they effect your particular vocal mix. If a performance feels muddy, try cutting a bit around 240-250 Hz. If sibilance is particularly harsh, sweep between 4 and 7 kHz to find the most offensive frequencies and tame them. As always, listen and use what best suits your personal taste.
4. Don’t Neglect Reverb Pre-Delay
When we use reverb, we’re trying to create a “space” for a mix element to live. Oftentimes we add it with the intention of bringing our vocals to the front, when in reality we find we’ve only pushed them further away.
The quick fix? Pre-delay. Many reverb plugins have this parameter, and it functions by separating the dry signal from the wet signal via a user-set delay. The result is hearing the space and dimension that we wanted from our reverb without pushing the dry vocal into the recesses of the mix.
5. De-Ess, De-Ess, De-Ess
Sibilance–that hissing noise produced with “s” sounds–is a naturally occurring phenomenon within the human voice. While we don’t consider it unpleasant in conversation–if we notice it at all–on a recorded vocal, sibilance can often be overwhelmingly harsh.
Using a de-esser to control sibilant frequencies, generally somewhere between 4 and 7 kHz, is crucial. A great de-essing plugin will retain presence/clarity without totally flattening out an exciting performance.
An awesome trick for mixing vocals is to boost the top end with an EQ and control it with a de-esser. You’ll get the brightness and clarity from boosting with the EQ, minus the exaggerated “s” and “t” sounds thanks to the de-esser.
6. Mix in Context
This concept applies to every element in your mix–not just vocals. Soloing a track and making it sound fantastic by itself is nice, but what about the bigger picture? When we rely on the solo button for too long, we lose our frame of reference and can find that the processing we’ve done doesn’t sit right in the full mix.
We can save time and avoid headaches by frequently un-soloing to make sure the changes we’ve made are working. No one wants to reach the end of a long signal processing chain to find their vocals sound amazing–but only by themselves.
The 6 steps above should provide some tips and tricks to try out next time you’re mixing vocals. Don’t be afraid to take these guidelines and run with them. As always, trust your ears!
