Stereo microphone is a process of recording multiple soundtrack tracks during film production. The signal-to-noise ratio, dynamic range, bandwidth, distortion, and crosstalk and phase shift of the main soundtrack material of the movie stereo are all stricter than those of the mono video. Recording system that digital video camera audio system. Most of the digital camera recording system for the PCM stereo digital recording system, optional 12-bit (recording frequency of 32KHz, two-channel) and 16-bit (recording frequency of 48KHz, two-channel) two different modes of recording. Let's take a look at the recording technology of a digital recorder.
Stereo recording on a digital recorder has a cross-shaped microphone shape that is much more complex than we thought to be with mono recording.
Recording dual-channel stereo, the main difference between time and sound pressure to create a three-dimensional sense of space, the time difference is the sound source to reach the left and right ears of different time and produce three-dimensional sense of sound pressure is different from the ear to receive the sound intensity and produce three-dimensional.
BOYA BY-V02 is a stereo condenser microphone，for use with DSLR cameras, camcorders, and audio recorders, it features cost effective is an ideal for video use. The BY-V02 measures 5.94" (151mm) in length and includes a dead kitten windscreen, camera hot-shoe mount, and replaceable rubber O-rings suspend the microphone on the shock mount and protect against noise due to movement and handling.
For stereo recording, there is another important factor is the phase. When using speakers or mixing left and right channels into mono, the same phase of the left and right channels increases the volume, but decreases the volume. Active noise reduction devices used in aircraft and some cars reduce noise by outputting sounds of opposite phases.
Stereo microphone placement (also known as standard) is very complicated, commonly used are the following:
A / B mode: two microphone pulled apart, parallel or at a certain angle toward the sound source. Simple but easy to produce sound field and phase problems.
All of the songs and pure music we hear are recorded by a microphone. Simply speaking a microphone represents a mono. General recording with multi-track vocals and various instruments, the resulting music is stereo.
