Some basic mixing technique may be corrective enough to reduce any noise problems to the inconsequential. It is wise to have water available in glasses (plastic bottles can be noisy), a notepad (to aid memory and reduce unwanted interjections) and clean cloths (to dampen sneezing/coughing or other personal disasters). foam/fiberglass/cloth absorbent panels) and place diffusors on the closest walls to scatter sound waves and stop the dull muddiness that results from too much absorptive treatment in a small space.Īll speaking talent will need closed-back headphones that don’t leak sound excessively, a pop filter on their mic to reduce plosives and enough room to back-off of the mic when needed. Seal up windows, cover them with blankets, seal up doorways with weather-proofing (whether an interior or exterior door), dampen air ducts, reduce unwanted room ambience with acoustic treatments (ie. Make sure the room is devoid of anything that creates sound, including fridges, air purifiers, computers, cell phones or even hummy DC adaptor “wall warts”. Start with a room that allows spacing between the persons, with each speaker in the null(s) of the other’s mic(s) and seated in a circular pattern for large groups, which encourages interaction, allows more visual communication and rejects mic bleed. Start with a room that allows spacing between people, with each speaker ideally seated in a circular pattern. Capturing the cleanest signal possible helps iZotope Rx 8 Advanced create better processing results later on. The cleanest and purest signal possible will ensure less severe processing, more successful processing and undetectability. I’ll be using iZotope Rx 8 Advanced premium software in my examples, but there a number of competing programs that accomplish the same goals, in sometimes similar manners.īefore we delve into fixes, some effort should be spent making sure we are capturing the best audio we can before applying processing. Luckily today’s digital, analytical, often aided by machine-learning software programs (and certain hardware pieces) are capable of not only mitigating, but downright removing extraneous noise. It can be hard to stay focused on dialogue when competing voices, air conditioning, ground hums, noisy appliances, passing trucks, airplanes, sibilance, plosives, ticks, clicks and massive vortexes (actually breaths, amplified to ridiculous levels) are stealing our attention. Yeah right! The truth is that for most of us voice recordists producing podcasts, audio books and interviews our audio is polluted with unwanted sounds of numerous varieties that must be prevented or removed if we expect rapt attention to the content. With hosts, guests and talent comfortably seated in your purpose-built and acoustically-treated isolation room, the discussions are easily recorded with minimal bleed, defined clarity and no intrusion or distraction from unwanted sounds and noise. IZotope Rx 8 Advanced offers a number of modules for cleaning up spoken-word material, including (seen here) De-plosive, Spectral Repair, Voice-De noise, Dialogue De-reverb, Breath Control and Mouth De-click.
