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.

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. low-frequency-15.7z
If you are dealing with a recording containing this or other unwanted frequencies, engineers typically use: This specific spike has been famously identified in
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: If you are dealing with a recording containing
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.
