To mix a song, you balance every element so nothing fights for the same space: set clean gain levels first, carve room with EQ, control dynamics with compression, place sounds across the stereo field, and build depth with reverb and delay so the listener hears one clear picture instead of a pile of tracks. A good mix is not about loudness or fancy plugins. It is about decisions - what should be loud, what should be quiet, what should sit forward, and what should sit back. Get those relationships right and the track translates to phones, car speakers, earbuds, and club systems without falling apart. This guide walks the whole process from a raw session to a mix that is ready to master.
What is mixing, and how is it different from mastering?
Mixing is the stage where you take all the individual tracks in your session - drums, bass, synths, vocals, and everything else - and blend them into one cohesive stereo file. You control the level, tone, dynamics, and position of each element so they work together. Mastering comes after that. Mastering takes your finished stereo mix and polishes it as a whole: final tone balance, loudness, and consistency across an album or against commercial references.
The simplest way to think about it: mixing is about the relationships between parts, mastering is about the finished whole. You cannot fix a bad mix with a great master. If the vocal is buried or the low end is muddy, mastering will only make those problems louder. That is why you finish the mix first, then master. If you want a deeper breakdown of where one ends and the other begins, read mixing vs mastering.
Where do you start when mixing a song?
You start with gain staging, which just means setting sensible levels before you touch a single plugin. Bring every track down so your loudest peaks sit somewhere around -6 dB and your master bus is not clipping. Working with headroom gives your plugins clean signal to work with and leaves room for the master later. If you start with everything slammed to the top, every EQ move and compressor adds gain on top of gain, and the mix turns into a wall of mush.
Once your levels are safe, build a rough balance with faders only. No EQ, no compression, no reverb - just volume. Get the kick and bass solid, sit the vocal where you can hear every word, and place everything else around that. This rough balance is the most important part of the whole mix. If the song already sounds good with faders alone, every plugin after that is a refinement rather than a rescue. If it does not sound good yet, no plugin will save it, and that is your signal to keep moving faders until it does.
How do you use EQ to make everything clear?
EQ is how you carve out space so each sound has its own lane. The most common problem in amateur mixes is that too many elements occupy the same frequency range and smear together. Your job is to decide what owns each part of the spectrum and cut the rest back.
Start with a high-pass filter. Roll off the low frequencies on anything that does not need them - vocals, guitars, synths, hi-hats, most percussion. There is a huge amount of unused low-end rumble under 100 Hz on tracks that are not the kick or bass, and clearing it out instantly cleans up the whole mix. Then look for build-up in the low mids around 200 to 500 Hz, where "mud" lives. When too many tracks pile up there, the mix sounds boxy and tired. A gentle cut in that region on the offenders opens everything up.
Think in terms of subtraction before addition. Cutting what you do not want is usually cleaner than boosting what you do. Boost only when a sound genuinely needs more presence or air, and do it with a wide, gentle band. If your mix feels cloudy no matter what you do, work through how to fix a muddy mix for a step-by-step fix. For vocals specifically, the exact cuts and boosts that make them cut through are covered in how to EQ vocals.
What does compression actually do in a mix?
Compression controls dynamics - the difference between the loudest and quietest moments of a sound. It turns the loud parts down (or the quiet parts up, depending on how you use the makeup gain) so a track sits at a more consistent level. That consistency is what lets a vocal stay present through a whole verse instead of jumping forward on loud words and disappearing on soft ones.
The controls that matter most are threshold, ratio, attack, and release. Threshold sets where compression kicks in. Ratio sets how hard it clamps down. Attack decides how fast it reacts, which shapes how much punch and transient you keep. Release decides how fast it lets go, which affects how natural it feels. A slow attack keeps the snap of a drum or the front of a word; a fast attack tames peaks harder but can dull the life of a sound.
Do not over-compress. If you squash everything flat, the mix loses its breath and starts to feel lifeless and fatiguing. Use compression to steady a sound, not to kill it. For vocals, which almost always need it, the full approach is in how to compress vocals.
How do you get the low end and 808s right?
The low end is where most home mixes fall apart, because you often cannot hear it properly on small speakers, and it eats more energy than any other range. The first rule is that the kick and the bass (or 808) need to share the low end without stepping on each other. If both are fighting for the same sub frequencies, the low end turns into a muddy, undefined boom that pumps and loses punch.
The usual fix is to give each element a clear job. Let the kick own the punchy attack while the 808 owns the sustained sub weight, and use sidechain compression so the bass ducks slightly every time the kick hits. That tiny duck keeps both audible and gives the groove its bounce. High-passing everything else off the sub region keeps the bottom clean so the low end feels tight instead of woolly. Because 808s carry both pitch and weight, they need their own treatment - saturation to make them audible on small speakers, tuning to the key, and careful level control. Everything specific to that lives in how to mix 808s.
How do you use panning and stereo width?
Panning places sounds left to right across the stereo field, and it is one of the fastest ways to un-clutter a mix. If everything sits dead center, every element is competing for the same spot and the mix feels narrow and crowded. Spread things out. Keep the anchors - kick, bass, lead vocal, snare - in the center where they belong, then pan supporting elements like hats, background vocals, guitars, and ear-candy out to the sides to create space and width.
Width is not just panning, though. Stereo effects, doubled parts, and subtle widening can make a mix feel big and immersive. Just be careful: the more you widen, the more you risk phase problems and weak mono playback. Keep your low-frequency information - kick, bass, sub - in mono, because low frequencies do not benefit from width and can lose power when spread. Width belongs in the mids and highs, where it makes the mix feel open without hollowing out the core. If your mix feels flat or small, opening up the stereo field is one of the moves covered in how to make a mix sound fuller.
How do you create depth with reverb and delay?
Panning handles left and right. Reverb and delay handle front and back. Depth is what turns a flat, two-dimensional mix into a space you can picture. A little reverb pushes a sound back and glues it into the room; a dry, up-front sound feels close and intimate. Using different amounts of reverb on different elements creates a sense of distance - the lead vocal stays close and dry while background parts sit further back in more space.
Delay is often better than reverb for keeping things clear. A timed delay adds size and movement without the wash that heavy reverb creates, so the vocal can feel big while staying crisp and present. Use sends rather than inserts so multiple tracks share the same reverb or delay, which glues them into one believable space and keeps your CPU sane. And keep effects out of the sub range by high-passing your reverb and delay returns, so all that added ambience does not clutter the low end.
How do you make vocals sit in the mix?
Vocals are the hardest part of most mixes, because they are the focus and they carry the most detail. A vocal that sits right feels effortless - loud enough to lead, clear enough to understand every word, and glued to the beat instead of floating on top of it. Getting there is a stack of small moves rather than one trick.
Start with level and compression so the vocal stays steady and present through the whole song. EQ to carve space, cutting mud in the low mids and adding a touch of presence and air up top so it cuts through the instrumental. Then use a little reverb or delay to place it in the same space as the beat, so it does not sound pasted over the top. The order and the reasoning behind those moves are laid out in how to mix vocals into a beat. If you want the fastest possible route to a broadcast-ready vocal without diving into every plugin, Vocal Polish handles the balance, tone, and presence for you.
How do you make a mix fuller and louder without crushing it?
Fullness and loudness are two different problems that people often confuse. Fullness is about frequency balance and layering - making sure the whole spectrum is covered so there are no gaps that make the mix feel thin. You get it with good arrangement, layered sounds, saturation that adds harmonics, and careful low-mid balance, not by simply turning everything up. When a mix feels empty, it is usually missing content somewhere in the spectrum, and the fixes for that are in how to make a mix sound fuller.
Loudness is about perceived volume, and the trap is chasing it by slamming a limiter until the mix distorts and pumps. The real answer is a clean, controlled mix that already has consistent dynamics, so the master can bring up the level without a fight. Tight low end, controlled peaks, and balanced tone all translate into a mix that gets loud gracefully. For the full method, work through how to make your mix louder. Loudness is best treated as a mastering job, not something you force during the mix.
How do you fix a mix that sounds muddy?
Mud is the single most common complaint, and it almost always comes from too much energy piling up in the low mids, roughly 200 to 500 Hz, plus low-frequency rumble on tracks that do not need it. When every element has its full bottom end intact, all that energy stacks up and turns the mix into a cloudy, indistinct blur.
The fixes are systematic. High-pass everything that is not carrying real low end. Find the tracks that are contributing to the low-mid build-up and cut them back there. Make sure only one or two elements own the sub region. Check that your reverb is not washing the whole mix in low-mid energy. Do all of that and the mix clears up dramatically, and instruments that were hidden start to breathe. The complete checklist lives in how to fix a muddy mix.
Why does mono compatibility matter?
A lot of listening happens in mono or near-mono: single Bluetooth speakers, phone speakers, club systems summed to mono, and plenty of laptops. If your mix falls apart when summed to mono - the vocal drops in level, the bass thins out, or a widened element vanishes - a huge share of your audience hears a broken version of your track.
The usual culprit is phase problems from heavy stereo widening or out-of-phase doubles. Check your mix in mono regularly while you work. If something disappears or gets weaker, back off the widening on that element or fix the phase relationship. Keep your low end in mono, be conservative with stereo effects on important parts, and your mix will hold up everywhere. Mono compatibility is not about making the mix narrow - it is about making sure the width you add survives the trip to real-world speakers.
How do you know when a mix is ready to master?
Your mix is ready when it sounds balanced and clear at a comfortable volume, translates across multiple playback systems, and has headroom left for mastering. Practically, that means leaving your master bus peaks around -6 dB with no clipping and no limiter slammed across the whole mix. Mastering needs room to work, and a mix that is already crushed leaves nothing to polish.
Test it. Play it on your monitors, your headphones, your phone, and your car if you can. If the balance holds up - vocal clear, low end tight, nothing harsh or buried - across all of them, you are done. Do not chase perfection forever; at some point the mix is good and it is time to hand it off. Take a break, come back with fresh ears, do one last check, and then master it.
