What is Post Production Sound Mixing?


Oftentimes when individuals ask me how my week is going or inquire into how my weekend was, my reply is “I have been/was mixing all week/weekend”. Nevertheless, I virtually all the time get a standard response, after they tilt their head like a confused canine does, “What kind of mixing?” or “What exactly is it you do?”

I typically overlook that folks outdoors this area may be overseas to what I do and what I contemplate widespread sense. Even individuals in my business have very limited information as to what goes on through the postproduction (submit) audio mix part. So I will do my greatest to offer a layman’s overview on what mixing entails and what my basic process is.

What do you mean by sound mixing?

The essential definition of sound mixing is taking all the elements of the movie’s soundtrack, i.e. dialog, SFX, Foley, and Music, and mixing them collectively to create one thing that sounds good. (For the document, SFX means special results like gunshots, automobiles, and so on. Foley means more “person” noise, corresponding to footsteps, clothes noise, eating noise, or the sorts of noises brought on by an individual.)

In additional specific terms, mixing/modifying is taking the dialog and making sure it is clean and usable. Any dialog that is not usable will want ADR (Automated or Automated Dialog Alternative), which is recording the dialog in a studio during submit with the actors. In addition to the dialog being clean, it also needs to be leveled so your dynamic vary is not leaping far and wide. Principally this means bringing the quiet elements up and the loud elements down.

SFX and Foley have to have this similar process finished. SFX and Foley have to be placed at proper volumes so you don’t have footsteps louder than dialog. Music must be added or composed and its degree must be automated so the music is not too loud or too quiet.

Once these elements are accomplished, every little thing needs to be combined together as an entire in order that in the long run there’s one seamless audio monitor that permits every facet of the film’s audio to reside in its own proper area.

The first thing I do once I start engaged on a new film venture for submit is to observe the picture lock edit, the place the video edit is last. From this I can study rather a lot concerning the amount of work that shall be concerned and what I’ll have to do. I wish to make notes of what sort of ADR I will need to schedule, and what sort of environments within the film I will need to painting sonically. At this level I also speak with the Director/Producer about any sound design that could be needed.

Once that is achieved I often get an OMF file of the film audio monitor from the editor and import that into the DAW I’m using. This is the place I spend quite a bit of time organizing. I take all of the dialog clips and put that onto its personal tracks. I do the identical factor for all the SFX, Foley, and Music(if any). I then create a Aux monitor(Stem), and have all the like tracks funnel into one monitor. By having all of these things tunnel into one monitor, it permits me to have control over the dialog or SFX as an entire. For example, if I need to make a whole scene’s dialog louder I can with simply make a couple of changes to the stems fairly than the individual tracks.

Essential Gear for Sound Mixing

So far as gear, aside from having a top quality pc that can deal with the processing of audio modifying/mixing, an important factor to have is quality reference screens. The distinction between screens and speakers is that speakers may be barely EQ’d to make music and films sound a bit of better. Screens often have a flat EQ to them. So you will hear issues exactly as they have been recorded. This allows you to combine so that your undertaking will sound its greatest regardless of what sort of audio system it is heard on in the long run.

Points involved with Sound Mixing

For probably the most part I discover the blending course of very artistic and satisfying, but there are typically points to be overcome. One difficulty I encounter is when the production dialog was not recorded correctly. Having a talented Sound Mixer on set is key to make postproduction sound mixing a lot simpler. One of many advantages of being someone who does manufacturing and postproduction audio is that it allows me to report the audio on set that I know I will need to save time in submit.

Along with that, surroundings noises could be difficult at occasions. Coping with setting noise like crowds and planes can create numerous time-consuming work. Typically uncontrollable environments can change from take to take so that once you edit a scene collectively, you might find that one shot has airplane noise and the subsequent doesn’t.

However the largest and most constant problem I’ve to cope with is time. Huge finances Hollywood films have a workforce of publish sound individuals and may spend six months or more in publish for audio. Within the indie world we don’t have this luxurious. Typically I have a weekend to get a brief accomplished or only a few months to complete a function. Making an attempt to do what teams of five or extra guys do in only two months is very irritating and troublesome at occasions.

Nevertheless, the satisfying elements of mixing far outweigh the challenges for me. I noticed I loved mixing the very first time I used to be hired to do it, which was for an indie function movie. Coming from a background in music recording and stay sound, I felt little to no artistic management in these fields, however movie was an entire new ballgame with infinite artistic prospects. With the ability to put my stamp on every challenge I work on provides me a much bigger feeling of function than I ever had before in other fields.

Why I really like what I do

Once I started submit sound mixing there wasn’t any strong information on the market on “How to mix audio”, so I sort of went into it blind. I approached it as if I used to be mixing a music for a band, and it had a number of similarities, nevertheless it was also much more work than I ever anticipated. Nevertheless, the errors I made on that first undertaking put me on the right path to the place I’m immediately.

I proceed to work in this subject as a result of I have loads of management over the emotions and emotions which are portrayed within the general film. I have a say within the forms of SFX used and designed. I have influence over the music that goes into the movie, or at the least an opinion, as well as how mushy or loud this music is. It is shocking how much one music can change your complete feeling of a scene.

It’s additionally fascinating to note that because sound and what you hear in day by day life becomes second nature, it’s a particular problem to duplicate that in a movie. Individuals will concentrate on loud sound in their day-to-day life, but for probably the most part we don’t even acknowledge what we hear all through our day. Even for those who have been to take a seat and take heed to the whole lot round you at this very second you’d in all probability decide up on rather a lot because you are focusing on it, but when asked to name every thing you heard in the final 10 minutes, you’d in all probability solely be capable of recall what you’re presently listening to.

In terms of mixing, it is my job to create the identical feeling. If dialog is out of sync, a footstep too loud, or the setting doesn’t match the visual, the mind will decide up on this instantly, but if it is all combined nicely, until you give attention to it, you gained’t discover it.

Sound individuals often don’t get recognized for distinctive sound, however it is all the time identified when it is dangerous. I all the time go together with the philosophy that when sound is not talked about in a assessment, meaning I did my job.

Most moviegoers in all probability don’t understand how much of what is heard in a movie is not from the original manufacturing audio however is added in later. How much of the audio is changed all will depend on the type of film. In massive blockbuster Hollywood films, little or no of what you hear was in all probability recorded on set. Actually I keep in mind watching something concerning the sound workforce for “Life of Pi” they usually mentioned you possibly can rely on one hand how a lot of the manufacturing dialog was usable for the movie. Which suggests most of that movie was executed in a studio.

Smaller scale indie films are a unique story. For a lot of the unbiased films I work on, I try to use manufacturing audio as a lot as attainable because it should sound probably the most pure. ADR is not the simplest thing to make sound like the unique surroundings. Nevertheless, typically I will use strains from totally different cleaner takes to keep from having to do ADR.

However it doesn’t matter what, I’m all the time learning and advancing my expertise. Sound is something that is all the time changing, whether it’s with new codecs or methods. It is a dwelling factor. No two movies I work on are ever accomplished the identical means. Every one is better than the last as a result of I take information and expertise and build upon it. Only recently I combined my first indie movie in Encompass Sound and it was quite the training curve. Nevertheless, now I’ll take what I discovered and the mistakes I made and proper them for the subsequent one.

And that’s it. That’s “What is Sound Mixing 101”, and why I personally take pleasure in it as much as I do. The subsequent time you see a movie, I hope this provides you an added appreciation for a way a lot of your enjoyment of film comes by way of your ears in addition to your eyes.
