Headphonesty — "192 kHz Is Worse Than 44.1 kHz for Most Music"

Headphonesty, May 2025 — that is the URL path, /2025/05/, and it is all the dating the page offers: no byline, no visible publication date, no day. No published: is recorded in this page's frontmatter for that reason; a day would be invented. A roundup of six named practitioners arguing that 192 kHz/24-bit distribution is at best pointless and at worst slightly worse than CD standard. It runs no test of its own — everything here is quoted and linked from elsewhere, which is what puts it at T3 under this spoke's rule of tiering a page by what it rests on.

It arrives on a subject the corpus already holds at primary level, and the interesting part is the gap between them. See sample-rate for the mechanism as this wiki now records it.

The argument, as made

Nyquist first. Human hearing runs roughly 20 Hz–20 kHz, so 40 kHz sampling covers it; CD's 44.1 kHz exists to give the anti-alias filter room to "roll off gently before the Nyquist limit," reducing pre-ringing and phase distortion.

Then the claim that gives the headline its verb. Ultrasonic content above 20 kHz is not merely useless but a hazard, because consumer amplifiers and tweeters are not built to reproduce it and respond nonlinearly when asked to. Christopher "Monty" Montgomery of Xiph.Org is quoted:

192kHz digital music files offer no benefits. They're not quite neutral either; practical fidelity is slightly worse. The ultrasonics are a liability during playback.

with his worked example of two ultrasonic tones (30 kHz and 33 kHz) producing audible intermodulation distortion on imperfect hardware, and the summary "Its playback fidelity is slightly inferior to 16/44.1 or 16/48, and it takes up 6 times the space." Dan Lavry of Lavry Engineering, a converter designer, is cited from his own white paper: "Sampling at 192kHz is about 3 times faster than optimal. It compromises the accuracy, resulting in distortions."

Then the listening evidence. Mark Waldrep (AIX Records) is quoted saying blind studies with hundreds of listeners showed "no perceptible fidelity improvement" over CD. And the article's strongest citation is one this wiki already holds as a primary: Meyer and Moran's Boston Audio Society study (meyer-moran-adda-loop), quoted correctly —

The CD-quality A/D/A loop was undetectable at normal-to-loud listening levels… by any of the subjects, on any of the playback systems.

Then the practitioners. Bob Katz (mastering engineer, author of Mastering Audio): "48kHz/24-bit is a big, big difference… more than going to 96 or 192. High-res doesn't make it sound better. The decisions made in the recording and mixing process [do]." Dan Worrall: "Any audible difference between 44.1 and 96k? Negligible to inaudible… All that matters are the choices you make when mixing." Paul Maunder, a Pro Tools-certified field sound supervisor, adds the production-side cost: higher rates load the CPU, cut plugin headroom, and raise distortion risk in nonlinear processors such as saturators and vintage-modelled plugins.

And the concession, which is the most useful paragraph in it. High rates do have a job — during production. Pitch shifting, extreme EQ, time stretching and plugins that need oversampling to avoid aliasing all benefit from headroom above the audio band. Worrall's framing is that these are "engineering conveniences, not playback enhancements," and Katz masters at 48 kHz/24-bit. The article's answer to why 192 kHz reaches consumers anyway is marketing: "Slapping '192kHz' on an album is easier than doing a real remaster."

Where it overstates its own evidence

The headline says 192 kHz is worse. The evidence assembled underneath splits into two kinds that do not support that equally.

The listening evidence is a null result. Meyer and Moran found no audible difference; Waldrep reports the same. A null says nobody could tell, which is an argument that 192 kHz is pointless, not that it is worse. Used the other way it is the classic error of reading absence of evidence as evidence of a direction.

The worse claim rests entirely on the mechanism argument — ultrasonic intermodulation in equipment not designed for it — and that argument is a prediction about playback hardware, not a demonstrated listening outcome. Montgomery's 30 kHz/33 kHz example is an illustration of how the nonlinearity would work, not a report of anyone hearing it. Nothing quoted here measures audible IMD from real ultrasonic music content on real consumer gear.

So the honest reduction of this article is: no audible gain, a plausible mechanism for a small loss on imperfect equipment, six times the storage, and a real production-side cost in CPU and headroom. That is a weaker and more useful claim than the title.

What it leaves out

The AES paper that disagrees. digital-filter-audibility (Stuart & Craven) ran double-blind discrimination on the filters inside digital audio and found listeners are sensitive to them — the counterweight this wiki keeps beside Meyer and Moran as an unresolved tension. The article cites the study that supports its conclusion and not the one that complicates it. That is the ordinary shape of advocacy journalism rather than a scandal, and it is exactly why the corpus grades this T3 and keeps the primaries above it.

Bit depth is conflated with sample rate. Katz's quoted line is about 24-bit being the meaningful step, which is a different axis from sampling frequency; the article files it under a sample-rate argument without marking the switch.

Nobody is counted. "Experts agree" covers six people selected for agreeing. No survey, no denominator, no dissenting engineer quoted.

And it is affiliate-monetized — the page carries "Purchases made via our links may earn us a commission" above the first line, on an article whose closing advice is to spend money on headphones and speakers instead of on file formats.
