Understanding Mouth Noises andPlosives
Before diving into liquation strategies, it is essential to requenze the two distint type of unwanted sounds: mouth noises and plosives.
Mouth Noises
Mough noises included the speaker clicks, smacks, lip sounds, tongue clicks, and audible saliva. They occur when the speaker simps; rsquo; s mough is dry, when thee tongue or lips part suddenly, our when when swallowing between frases. They are of ten unslemous and vary from person.

PlosivesCity in Germany
Plosives are the harsh popping sounds produced when n pronouncing stop consonants like P, B, T, D, K, andCity in Germany G. Tese consonants involve a complete blockage of airflow followed by a sudden release, creating a burst of air. When that burst hits the microphone diaphone diaphreg directly, it causes a low-frequency thump or a sharp transient that can overload the preamp. Plosives are specilarly problematic wich large-diaphrasm condenser miphones and when the speaker is too cloche to the mic.
To zrozumiałe, że te acoustic cause of each problem leads to targed solutions. Many techniques adors both conteneously, but a few are specific to one type.
Microphone Selection andSetup
Te choice of microphone and how it i s positioned can dramatically feeft thee prevalence of mouth noises and plosives. Not all microphones are created equal in this regard.
Pick the Right Microphone for thee Job
- Mikrofony dynamiczne (np., Shure SM7B, Electro-Voice RE20) are generally mole forforforciving of plosives because their diaphragms are heavier and less sensitivie to low-frequency bursts. They also have built-in pop filters or grilles that reduce wind andd breath noise.
- Mikrofony Condenser (np., Neumann U87, AKG C414) capture more detail, including high-frequency mouth noises, but require careful placement andd pop protection. A large-diaphragm condenser im more contributible to plosives than a small-diaphragm or shootgun mic.
- Mikrofony Ribbon (np., Royer R-121) have a natural high-frequency roll-off that can reduce sibilance and mouth clicks, but they are fragile and need a dedicated pop filter to protect thee ribbon from air blast.
For dialogue work, a well-chosen dynamic mic with a cardioid Pattern is of ten thee easiest to work with in untreved rooms, while a condenser can deliver superior clarity when thee environment is controlled.
Optimal Microphone Placement
Pozycjonowanie is a cheap and effective tool. Te klasyczne zasady of thumb is to place thee microphone 6- 12 inches the speaker index; rsquo; s mouth, with the capsule aimed slightly off-axis (45 degrees left or right) rather than directly in front. This off-axis position reduces the direct airflow frem plosives whill capturing clear speech. Tilting the microphone dowd sward sd thet ipt pointiont tod thward the speaker move mmps; rsquo; s (instead of.
Jeśli te talenty to move their head while speaking, a larger working distance (10- 12 inches) gives more margin before plosives hit thee capsule. However, to far way inputes room tone andd reflections. A good comcomsome is to combinae a pop filter with a windscreen andd maintain a consistent distance.

Filtry Pop i Windscreen
Pop filters are te first st line of defense against plosives. They work by fizycally diffusing thee burst of air before it reaches the microphone diaphresm. Two type are e compann:
- Filtry Nylon mesh pop: They consist of one or two layers of fine mesh streched over a circular frame. They y effectively breake up airflow but can slightly reduce high frequencies, especially if placed too cloche to thee mic.
- Filtry metal mesh pop: Often made of perforated metal, thee e are more durable easyr to clean. They tend te be les acoustically transparent than nylon and can cause comb filtering if nott positioned correctly. Some premiummodels have a curved shape to further diffuse air.
- Wiatraki Foama: These slip over thee microphone capsule and work well for reducing wind noise and breath pops in outdoor or high-airflow situations. However, they can muffle high frequencies, and for indoor dalogue, a dedicated pop filter is usually more effectiva.
For best results, place thee pop filter about 2- 3 inches from the microphone capsule, and have the speaker position themselves 2- 3 inches from the pop filter. This creates a consistent spacing that minimizes both plosives and mouth noises while reserving clarity. If you still hear plosives after adding a pop filter, try tilting the entire microphone / pop filter assembly slightly ty thee side.

Acoustic Treatment andRecordng Environment
Kiedy nie ma bezpośredniego związku z tym, że to jest niemożliwe, to nie ma powodu, by myśleć o tym, że to jest niemożliwe, że to nie jest możliwe.
- Use absorptive panels or vocal booth to reduce early reflections.
- Umieść mikrofony na butach, w kolorze twardej skóry, like windows or bare walls.
- Ensure thee room has a low noise floor (turn off HVAC, fans, andd applicances).
A quiet environment means you can set lower gain, which dispens thee preamp noise loor and the perception of transient mouth sounds. This is especially important when recordg dialogue that will later be compressed or limited.
Speaker Technique andPreparation
Eun thee best microphone and pop filter cannot t compensate for pour technique frem thee talent. Educating the speaker (or yourself) on good habits is essential.
Hydration andMough Preparation
Dry mouth produces mone clicks andd smacks because the lips and tongue stick together. Drinking water at roem temperature ite simpleste fix. Avoid dairy products, caffeine, or sugary drinks before a session because they can create phlegm or dry out the throate before the throate.

Vocal Warm-ups andRelaxation
Tension in the jaw, throat, or shoulders leads to forced speech andd more plosives. Simple vocal warm-ups like humming, lip trills, and tongue twisters help relax thee articulators. A luxed speaker produces sfluther airflow, reducing thee intensity of plosives and the frequency of involuntary clicks.
Breath Control
Plosive are often worses when te speaker takes a deep breath juset before a plosive consonant. Enbouge the talent to breathie naturally, and t o avoid rushing into thee next frase. A pop filter will help, but controlled exhalation before a empf; ldquo; P consolumph; rdquo; or consolump; ldquo; B consolummph; rdquo; can make a surprising difference.

Consistency in Distance andd Angle
Przemieszczanie się na głowie zmienia się, gdy jest to możliwe, i w związku z tym zmienia się ta zmiana, która powoduje, że zmiany te są bardziej intensywne i często występują. Using a boom arm and a visual marker (like a loop of string or a laser pointer) can help thee speaker stay on axis. Many voye actors mark the foop tape to maintain a consistent spot.
Monitoring andd Feedback During Recordng
Co ty na to, żeby nie było cię na liście, ale nie możesz się z tym pogodzić.
Software solutions like Izotope RX Nie ma mowy, żeby ktoś się dowiedział, że to jest możliwe, ale oni są niebezpieczni, że nie są w stanie tego zrobić.
Post- Production Techniques
Despite bett efficults, some unwanted sounds will considente thee recording session. Modern audio editing tools offer several ways to clean them up.
Manual De-clicking
In a waveform editor (np., Pro Tools, Reaper, Audacity), you can zoom im on thee transient of a mouth click or plosive and either delete thee sampe, applicy a short fade, or can zoom om or tool too redraw thee e waveform. For istated clicks, this is often thee cleett method. However, it is time time-consuming for long dialogue tracks.
Spectral Editing
Tools like iZotope RX Spectral Or Adobe Audition Resimpl.rsquo; s spectral display alloy you tu see unwanted noises as bright spots or streaks in thee frequency domain. You can then selectively delete or attenuate those artifacts with out affecting the speech. Thii s specilarly effective for high-specipency muff clicks that appear at as narrow vertical lines.
De-essers andd De-clickers
Dedicate plugins like iZotope RX De-click, Waves WLM De-esser, or FabFilter Pro-DS can automatically decret and remove transients andd sibilance. Set te volold carefly to avoid removing thee natural clarity of consonants. For plosives, a multiband compressor or EQ witch a high-pass filter (cutting below 100 Hz) cain tame low-end thump.

Equalistion andd Compression
After removing the transient, a narrow notch filter at te plosive sound thin; rsquo; s rezonant frequency can further reduce the boom. However, be cautious: over-EQ can te voice sound thin. Compression will bring up the level of any equiing mouth noises, so is bett to maphyt ty compression only after yove cleaned the track.

Advanced Techniques: Blending and Finessie
When editing dialogue at a professional level, thee goal is invisibility. Sometimes thee best approach is to replacee a problematic plosive with a similar sound another take (compring) or to crossfade around it. In film dialogue editing, condimpf; ldquo; room tone accormph; rdquo; is captured so that small deletions can by masked by by by space fill. For a click that falls on a sibilt, u might borrothe mph; ldquo; S mp; dquo; fr; bd.
Another advanced trick is to use a de-clicker that analyzes thee audio in real time during recordg (some DAWs offer this an insert effect). If you trust your monitoring, you can applicy a light de-click one thee way in, reducing the workload in postt. But always end a clean backup track with out any real-time processing.
Putting It All Together: A Workflow for Cleun Dialogue
- Przygotujcie ten talent: Hydrate, warm up, and practice off-axis mic technique.
- Set up thee room: Choose a quiet, akustyka leved space. Place thee microphone with a pop filter 6- 10 inches the speaker permanent; rsquo; s mouth, off-axis.
- Monitoror closely: Usie closed-back headphone and listen for clicks and pops during thee take. Do note be afraid to retake problematic frases.
- Rekord at moderate levels: Avoid hitting thee preamp too hard; leave headdroom for poct-processing.
- Edit in poct: Start wigh spectral cleaning ig to remove obvious clicks. Then applicy a gentle high-pass filter tr reduce plosive low end. Usie a de-esser if needed, but prefer manual Editing for thee mott transparent results.
- Final check: Listen to the entire track witch compression and limiting in place te to ensure no residual noises are brough up.
By combinang preparation, proper gear, and careful Editing, you can accesse dialogue tracks that sound natural, professional, and free from distracting artifacts. Every extra minute spent at te recording stage saves ten minutes in poct-production.
