Warm Pink Noise — A Darker Pink-Noise Variant
Warm Pink Noise is a custom darker noise texture, not a second copy of our standard Pink Noise master. It prioritizes warmth and reduced hiss over strictly following the usual pink-noise spectral formula.

Press Play; nothing starts automatically. With JavaScript, the shared player keeps listening active across pages and gives access to Volume, Sleep Timer and Dark Screen. Native MP3 controls remain available without JavaScript.
This master passed automated source checks. The site owner has approved the current 10-minute audio master. Realism varies by listener; use a comfortable volume.
Compare Warm Pink Noise with other sounds
Hear the actual, different audio files. Switching selections preserves the existing sleep-timer deadline; recordings are not automatically matched for loudness. Start at a low volume when changing tracks.
To read details about another recording rather than just audition it, use its dedicated page: Pink Noise · Brown Noise · Soft White Noise.
What does Warm Pink Noise sound like?
Ideal Pink Noise has a slope close to −10 dB per frequency decade. The measured Warm Pink master is considerably more low-heavy, so the label is a perceptual description of this variant rather than a claim of textbook 1/f noise.
How it differs from related sounds
If you need a scientifically conventional Pink Noise reference, use our standard Pink Noise page. Warm Pink is better treated as an alternate bass-weighted listening option, with its true measured characteristics stated below.
Five-band spectrum of Warm Pink Noise
A custom low-weighted alternate render, not standard 1/f pink noise. This chart displays sampled decoded-signal amplitude density, grouped by frequency. Values come from our source QA measurement code; no frequency response is guessed from a color name.
Bars are relative to the strongest band of this track only, not calibrated SPL or loudness at your ears. Numeric dBFS values are for decoded source measurements, not decibels in the room. Audio was measured with 16,384-point Welch analysis across four sampled portions of the 10-minute master. The fitted 120–6,000 Hz spectral slope is -41.65 dB per decade. Digital integrated level: -25.5 LUFS; true peak -12.9 dBTP. Neither proves a particular hearing-safe volume.
Understanding Warm Pink Noise
What “warm” means for this file
Warm Pink Noise is a descriptive label for a custom 600-second recording, not a new conventional acoustic color. Ideal Pink Noise follows a power-density relationship close to 1/f, often described as −10 dB per decade. Our Warm Pink audio measures about −41.65 dB per decade over the analyzed range because additional shaping, including a cutoff around 2,000 Hz, strongly reduces much of the higher end.
It can therefore sound noticeably darker than standard Pink Noise, even though the word “pink” is still in its title. For textbook spectral comparison or audio measurement, use the original Pink Noise reference instead. This warmer variant is offered as a listening option with its actual measured behavior disclosed, not as a scientific calibration file.
Warm Pink versus Brown and Deep Brown
Although its upper range is filtered, Warm Pink still has a different measured profile from Brown Noise and the especially deep Deep Brown Noise variant. A darker tonal curve may be pleasant for some listeners, but the perceived result changes across earbuds, laptop speakers and full-range monitors. Compare at low volume and choose by sound, not by a claim of therapeutic benefit.
For conventional spectral definitions, see IEEE's colored-noise overview and the American Academy of Audiology's listening-volume caution. These are references for the physical principles, not endorsements of the recording.
Choosing a listening situation
Try it when standard Pink Noise feels too bright, comparing at a comfortable level. A low-heavy spectrum can reproduce differently on earbuds, laptop speakers and a larger speaker.

Questions about Warm Pink Noise
Is Warm Pink Noise the same thing as standard Pink Noise?
No. Its measured spectral tilt differs substantially from the conventional 1/f curve; it is a custom tonal variation.
Can I compare them using the same device volume?
You can, but the tracks are not automatically loudness-matched and equal percentage settings do not guarantee equal perceived levels.
Does the sound stop after ten minutes?
No. Ten minutes describes the MP3 master; the player uses continuous HLS or MP3 looping until stopped, the timer expires, or your device interrupts playback. HLS repeats the master rather than creating additional independent audio.
Does Warm Pink Noise follow the usual 1/f rule?
Not across the whole tested band. Its measured fitted tilt is −41.65 dB per decade after additional filtering, considerably steeper than ideal Pink Noise's −10 dB per decade.
How is Warm Pink different from simply lowering playback volume?
Frequency shaping changes the balance of highs and lows, whereas lowering a volume slider reduces the overall signal without changing its spectral distribution.
