If you are dealing with a recording containing this or other unwanted frequencies, engineers typically use:
Often used for true low-end rumble (20 Hz to 1 kHz). low-frequency-15.7z
This specific spike has been famously identified in major soundtracks, including Hans Zimmer's Interstellar . It is often debated in forums like Reddit's Audio Engineering community because many modern listeners using spectrum analyzers notice the spike, even if they can no longer hear that high a frequency due to age.

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? Managing Similar Audio Issues When dealing with low-end
In audio production, "low-frequency" usually refers to the 20–200 Hz range. However, the specific value is highly significant in technical circles for the following reasons:
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.
Tools like Soothe2 or standard notch EQs can target and remove a surgical spike like a 15.7 kHz whine without affecting the rest of the audio.
