AKARSH SHEKHAR Differences between MIXING AND MASTERING The differences: How to mix: How to master: Mixing creates a balance between individual elements whereas mastering gives your track a final polish. You can create a mix without mastering it, but you can’t master a recording without mixing it first. When someone’s done recording individual tracks, it's the time to mix. To make a rough mix, give each track an informative name. “Ld Vox” is easier than “audio_track_14.wav.” Instantiate gain plug-ins on each track to ensure that they are not too loud, not too soft, and about the same volume. Use your DAW’s faders to roughly approximate the levels for each track. Then, pan each track to create a balanced soundstage, while also giving each element its own spatial location. When your mix is finished, mastering is done to polish your mix up to its finest version and prepare it for distribution on CD, vinyl, or the internet. During mastering, you use linear-phase EQs, compressors, brick wall limiters, and vibe-enhancing effects like character EQs, stereo wideners, and tape saturation to give your mix a radio-friendly sound. Sufficient metering is also vital. A simple rock or pop mixing can contain 32 separate tracks, while complex projects can have track arrangements counts in the hundreds. Mastering sessions consist of one stereo or multitrack file per song, or possibly multiple stems. At both the mixing and mastering stages, you’re striving to achieve balance. During mixing, you’re balancing individual instruments. During mastering, you’re balancing complete songs and spectral broad strokes that affect the entire song. The mixing process is about enhancing the artist’s vision, making sure that the original emotional intent is conveyed. Mastering, on the other hand, is focused on sound quality. It ensures that the song sounds just as good (or better) than everybody else’s initial intent. Mixing gives you access to every instrument in a song. During mastering, you only have access to the final mix. This makes altering the balance between individual elements much more difficult. Next, apply high pass filters, low pass filters, and EQ to the tracks to carve out space for each element and to establish a tonally balanced mix. Compressors are employed to manipulate and contain each track’s dynamic range. Additional EQ and compression, as well as reverb, delay, modulation, saturation, and other creative effects are also applied to each track (and can also be applied to the entire mix, depending on your taste and preferences). Throughout the mixing process, you’ll be editing, adjusting pitch and time, manipulating fades, tweaking track levels, and applying automation. It’s important that your mix sounds equally great on a wide range of playback systems. That’s why it’s important to audition your mix on headphones or earbuds. Mastering is all about subtlety. If your mix needs to be drastically transformed to make it sound right, you should probably go back to the mixing stage and figure out what went wrong. Aside from providing sonic sweetening, mastering is the stage where an album is assembled. Adjust the volume of each individual song or add spacing and fades to the beginnings and endings of the songs — two seconds is the standard (not mandatory). Finally, label song names, add UPC/ EAN codes, CD Text, and ISRCs. Lastly, wait for a while after your mix is finished before starting the mastering process. This helps you regain the perspective and objectivity you’ve undoubtedly lost while you were slaving over your mix. Having somebody else master your mix is an even better idea. Both mixing and mastering are complex subjects and now you know their differences. The Score Magazine highonscore.com 35
