The boundary effect microphone uses a large flat surface, such as a desktop or floor, to reflect sounds to the capsule. The shotgun microphone - equipped with a blimp-mounted windscreen and shock-mounted on a “fishpole” boom - is often the prime microphone for video productions where a separate sound operator is involved. A shotgun can be mounted on the camera or held by a separate sound operator. Stereo shotguns can create a wider sound mix. A mono shotgun is used to pick-up sound at a moderate distance from the source while rejecting sounds around the sides. Shotgun microphone with wind protected blimpĪ shotgun microphone has a long, tubular design that resembles a gun barrel. Most inexpensive lavalieres are designed for single-purpose use and suffer deficiencies when used away from the body. #One man band video freeLav mics are popular because they leave the wearer’s hands free and keep the microphone a fixed distance from the mouth. Current models are so tiny, they are almost invisible. This microphone got its name from the cord that hung around the wearer’s neck. The lavaliere is the catchall term for a type of miniature microphone worn on the body. These microphones often cost under $100 and are essential tools for any video crew. Many models include integral windscreens and shock mounts that minimize the noise when the microphone is handled live. The handheld microphone, commonly used for man-on-the-street news-style interviews, can be held by talent or mounted on a stand. Each type has a unique purpose in video recording. There are five common physical microphone designs: handheld, lavaliere, shotgun, boundary effect and studio. If you’ve ever heard an interview recorded this way, you know depending on the in-camera microphone is a major error. Yes, the on-camera mic captures general ambient sound, but that’s about it. These problems can’t be fixed with 32-bit float audio recording.įor far too many videographers, the key microphone is the one built into the video camera. Of course, the video operator still needs to do correct mic placement and use the right mounting gear and wind protection when working in the field. If distortion is introduced before recording - say an overloaded mic capsule or power line hum - 32-bit float won’t help. But in normal one-person shooting situations, these new recorders can save the distracted operator from getting over-modulated audio. The downside is 32-bit float audio files are about a third larger than standard 24-bit files. These field recorders allow the recording of useable sound no matter how the level is set. #One man band video softwareMost video editing software and digital audio workstations can now play back 32-bit float sound. #One man band video portableThis is not turning on the camera-mounted microphone and setting the switch to “auto.” That old pot luck scenario for audio recording may have allowed the video operator to get by in the past, but it was never acceptable professional practice.Ī number of companies now make 32-bit float portable audio recorders, including Sound Devices, Zoom and Tascam. ![]() Fortunately, life has gotten a bit easier, thanks to new audio technology now being adopted in the field.Ĭalled 32-bit float recording, that new technology allows camera operators to record audio without worrying about setting levels. #One man band video how toThe key to high quality audio-for-video is a combination of the right tools and the human knowledge of how to apply those tools to the recording situation. ![]()
