Stereo Image Placement = Much Better Mixing

Uncategorized

This post focuses on the placement of sounds in the stereo image during the mix process.

Proper use of stereo imaging in a mix is probably almost as important (or even more important in sparse mixes) as equalization, yet it is largely overlooked as an area for improvement in engineers and producers of beginner and intermediate experience. Intelligent panning and equalization compose about 80% of a good mix, in my opinion.

The Stereo Field ‘Real Estate’

The stereo field can be thought of as your ‘real estate’ for sounds. In any real estate market, there are prime spots that should be reserved for ‘special’ things. In stereo, these spots are center, left, and right. When you choose to place anything in these key spots, make sure you have considered why. These are the spots that most affect the mix. Mixes with much use of hard panning will sound heavier and unfocused. Mixes with much use of the center channel can sound clustered and claustrophobic.

Conventions, Best Practices and their Reasons

As with any set of rules, these conventions can be broken to very good effect. There are good reasons for these standards to exist, however, and they have to do with the way sound is produced and heard. Back in the days of the Beatles, Abbey Road’s first console only had three panning settings: hard left, center, and hard right. Listen to their recordings before 1968ish and you’ll hear lots of unconventional panning (from today’s perspective).

Low frequency sounds such as kick and bass sound best in the middle. There are a couple of reasons why this is the case. First of all, sounds in the middle are being driven equally by both speakers. Bass sounds require a lot of energy to produce and having two speakers working at producing the sound means that the speakers don’t have to strain as much. Secondly, bass tends to be the foundation and anchor of the mix so, psychologically, having the anchor in the middle is reassuring to the listener. Choosing to have bass sounds panned will make a big impression on the listener… it’s obvious and catches attention. As such, panning a bass sound should be done in special circumstances when something specific is to be accomplished.

It is the natural inclination of just about everyone just starting out to pan reverb returns to full stereo: hard left and hard right. This is not a good idea unless your mix is very sparse. One of the things that reverb does is it defines the depth ‘space’ in which different sounds live. As such, it can also define the ‘space’, left and right, in which the sounds live. If one is contrasting a dry sound with a wet sound, panning the dry sound to ‘live’ outside the stereo span of the return makes the dry sound appear much drier and the wet sound appear much wetter. If the dry sound were to be panned within the span of the wet sound, its tight decay would be obscured by the decay of the reverb. Also, a hard reverb pan all the way to the left or right makes the edges of the mix sound muffled. As the left, right, and center channels are the most important, leaving these areas clear allows incidental and critical sounds to be heard without competition. If I need a reverb to return in the center, I pan the left and right channels ‘in’ a little bit (such as 80% right and 80% left). I often will pan a return exclusively to the right or left sides, ‘out’ from center and ‘in’ from the edges (such as 20% right and 80% right). Having reverb in the center of a mix will obscure the impact of critical rhythm sounds such as snares and kicks. The same general principles apply to delay returns, albeit a little less strictly as they tend to be sparser.

Another natural inclination of beginners is to pan stereo overheads and drum rooms hard left and hard right. This can work well for a very wide drum sound. However, in busy mixes it can sound better to bring the pan in a bit or even have the drums be mono altogether! Radiohead frequently uses mono drum overheads. I bet many of the records you listen to on a regular basis have mono drums and you haven’t even noticed. Mono drums give you more room to experiment and to fit sounds in the mix. Generally speaking, the simpler the drum part, the better it sounds in mono. Most ‘dance’ music has drums entirely mono to ensure that the entire club, both left and right, can hear the beat. This philosophy applies to other ‘club’ music, as well.

Rhythm guitars are generally placed very wide. If the guitars are a central part of the song and need to be heard prominently, panning them hard left and hard right makes sense. I usually make the wideness of rhythm rock guitars to be a top priority. If the guitars are merely texture, consider pulling them into the space in-between.

Avoid having any strident sounds panned to the edges of the mix, especially ‘sine’ type synthesizers. Ears don’t like sounds that don’t blend. Sine synths blend poorly and panning hard reduces blend even more.

Consider automating pans to create motion and to shift the image of the song from section to section.

Lead vocals are often panned dead center. This makes a lot of sense psychologically, particularly if the vocal part is solo and not doubled. If the part it doubled, it can be more effective to pan the doubles left and right a bit to make room for drums and bass.

Background vocals almost always sound best with an equal balance and with lower parts panned inwards. If the backgrounds are incidental, hard panning left or right can be very interesting. If the backgrounds repeat a lot, the 50%-70% ranges of left and right make a great target for carving out their home.

If you have a stereo synth sound to place, consider simply throwing away one channel. Often the other channel is merely a ‘chorused’ or delayed copy designed to make the preset sound bigger. Bigger is not always better in mixing.

Oh… and stereo widening gimmicks? Skip them. Leave that stuff up to an experienced mastering engineer.

General Philosophies for Panning

Some producers are really into documenting a performance. If this is your thing, it makes a lot of sense to pan the performers as they are literally spaced in their performance. Decide whether you want the image to be from the band’s perspective or the ‘audience’ perspective. If the drummer is considered the middle, the snare drum, for example, would be panned slightly to his left (provided he is right-handed), the hat further to the left, etc.

If you’re more interested in producing a unique environment, throw that idea out the window and do whatever you feel.

As you can see, panning is a complex and subtle process. To review… don’t have a bunch of things panned in the same area. If you find that certain sounds are ‘stacked’, try soloing those sounds and make sure they don’t interfere too much with each other. I like to have sounds evenly balanced in the space. A typical mix of mine would probably find sounds panned, from left to right: 100%, 85%, 75%, 65%, 50%, 30%, 20%, center, 20%, 30%, 50%, 65%, 75%, 85%, 100%.

Panning can be a lot of fun….

    One tell-tale sign of limited tracks in the 60s was the way “clumps” of instruments would pan around together.

  2. Alan says:

    I remember listening to Steppenwolf’s first album on a dodgy cassette deck that sometimes didn’t put out both channels.

    Various major instruments (guitar, organ) were completely missing depending on whether it was putting out the left or the right channel at the time. They had some hard-panned instruments!

    Don’t think I’ve seen any panning that extreme since.

    i must sound like such a noob but i searched stereo bus on google and this came up so would you be able to give me a detailed explanation of stereo bus because i dont know what it is

  4. Dan Connor says:

    Nathan – hey, it’s cool. It’s not a very intuitive phrase. Basically, busses are audio groups that you can pipe audio down, like off of a mixer or out of a workstation. The two main groups used to create a stereo output are called the stereo bus and usually have some special controls associated with them to control level and whatnot. You can also have a six-channel output bus for surround, for instance.

    Mike,
    Fantastic music & site. Everything sounds great. Love the vocals and all the arrangements.

  6. luke says:

    Super helpful and well written!

    Thanks!

  7. Shone says:

    Can I ask you a question?
    I’ve read some of the music production books, and they say some stuff about panning at 10:30, or 4:00, 9:00 etc.Can you explain what that means?
    Thanx

  8. Dan Connor says:

    Shone,

    Back when all mixing happened on analog mixing consoles, the knobs were circular, turned radially from left to right, and had a notch cut or a line drawn on them like a clock hand.
    Panning pot

    As you cans see, full left is about 8:00 and full right is about 4:00 with 12:00 being right in the middle.

  9. Shone says:

    Oh…I would never guess something like that!Thank you very much!
    I guess that that full left is 9:00 and full right 3:00…So is there any difference between 12:00 and 6:00?

  10. Shone says:

    Don’t answer to the last one,I totaly forgot that those knobs can only turn 2/3 of the whole circle :)

    Hey, I’m learning to mix from internet articles like your and am finding them so useful but one thing I come across is people talking about panning the same sound left and right to widen them in the stereo field. I tried this and noticed that they sill sounded like they were coming from the middle…which in stereo terms they were. I got around this by learning to put a slight difference in the two channels, IE, a very short delay on one of the channels, a few milliseconds, and hey presto the sound magically widens in the stereo field. I’ve done this with a tiny pitch shift too -0.1% mixed 100% wet on one channel, but it only works panned hard left and right, the closer you pan the more of a horrible out of tune chorused sound.
    Sorry for the long reply here but my basic point here is that if you pan an identical sound left and right it still sounds like it coming from the middle…a lot of people talk about panning left and right to widen the field but don’t mention this My question is am I doing something wrong…?? Should panning an identical sound produce a wider effect in the stereo field..??

  12. Dan Connor says:

    Your experience is exactly correct. Most people who suggest panning the same sound hard left and hard right don’t know what they’re talking about, unless the mix is very bare. What you’re doing with delay is basically what makes a ‘chorus’ effect turn mono sources into stereo sounds. It’s also what most synths use to produce ‘stereo’ sound. My recommendation is lose the second channel and mix with mono sources unless it’s ‘true’ stereo – i.e. was recorded with two microphones. Otherwise you’ll run into phasing issues that could turn everything to mush under certain listening situations.

  13. J-Rock says:

    My best advice is: firstly-AFTER RECORDING,fully EQ everything into it’s own frequency range so each track shines thru when played together. Then pan rhythm guitars 75-80% L & R. I would not go all the way out to 100%, as this leaves a big hole in the sides of center position. Use a modestly small amount of stereo width to your double tracks so as not to make things muddy. Pan drums from an audience point of view; panning from the drummer’s chair will sound unnatural, as people do not hang out by the drummer when listening to music. Also, in Rock music, NEVER AUTOMATE DRUMS FROM SIDE TO SIDE. THIS SOUNDS VERY AMATEUR so leave them in a set position. Do not compress every track unless needed, as this will kill dynamic definition overall. ALWAYS widen the low end of the stereo image less than the high end for a tighter sound. DO NOT USE THE SAME FORMAT FOR EVERY SONG, as every song is different in texture… and lastly, MAXIMIZE YOUR HIT! (that’s the fun part!)
    Most importantly, do not give up. Read all the help you can find and try everything til something works for your project.

  14. J-Rock says:

    Mixing is all about perspective. DO NOT MAKE ONE SPEAKER HEAVIER WITH TRACKS, as this will not be pleasing to the ear and you will quickly lose listeners. Your final master should sound BIG and right in front of you on speakers, and somewhat surrounding you with good headphones.

    PROBST!

  15. Dan Connor says:

    Naturally. The real question, of course, is how to achieve that big sound :)
