Often used for true low-end rumble (20 Hz to 1 kHz).
15.734 kHz is the horizontal scan rate of legacy NTSC analog video displays (CRT monitors). In recording environments like those used for film scores, if a CRT screen was used—for example, to communicate with a musician or display a score—it could create a high-pitched "whine" captured by sensitive microphones. low-frequency-15.7z
When dealing with low-end frequencies (bass/kick), it is critical to ensure phase alignment to prevent "wobbly" or weak sounds. 7 kHz noise from your own audio? Often used for true low-end rumble (20 Hz to 1 kHz)
If you are dealing with a recording containing this or other unwanted frequencies, engineers typically use: engineers typically use:
