Turn a reference track into a style prompt
Load a track you like, let the page measure its tempo, brightness, weight, density, dynamics, stereo image and vocal presence, then read back a Suno-grammar style line in English and Turkish — plus the closest entries in this site's own styles library.
Every value below is an estimate computed from the decoded audio in your browser. The result describes measurable properties — tempo, spectral balance, dynamics, stereo image — and turns them into a prompt you can paste. It is not a copy of the reference recording, it does not extract stems, and it cannot reproduce the original performance or production.
1 · Reference track
Waiting for a trackmp3, wav, flac, m4a and ogg are decoded by the browser. If a file cannot be decoded, the status line says so instead of guessing.
2 · Measurements
All values are estimates, not certified measurements.
3 · Style prompt
Descriptor order is fixed: genre → instruments → mood → vocal → production → tempo.
Opens the builder with this style line already filled in, in the language you are reading the page in.
4 · Matches in the styles library
0 entries in the libraryScored against this site's own styles library by shared tags, category, mood, prompt wording and tempo proximity.
5 · What to tweak
Short, concrete changes that would move your reference closer to the matched style — or make the prompt describe your reference more exactly.
How each number is estimated
Tempo: autocorrelation of a spectral-flux onset envelope, folded into the 70–180 BPM window. Half- and double-time reads are common and expected.
Brightness: the average spectral centroid across analysis windows, in Hz. Higher means more energy sits high in the spectrum.
Warmth: share of total spectral energy below 250 Hz.
Density: peaks in the onset envelope per second — roughly how busy the arrangement is.
Dynamics: crest factor, peak over RMS in dB. Low values mean a squashed, heavily limited master.
Stereo width: side energy over mid energy, clamped to 0–100%. Mono files report mono.
Vocal presence: a heuristic from how much energy sits in 300–3500 Hz and how strongly that band moves frame to frame. It is a hint, not a detector.
Questions
Does my audio leave this device?
No. Files you pick are decoded in the page. Only a link you paste yourself is fetched, and that goes through this site's own proxy so the browser can read it.
Why does the tempo sometimes read half or double?
Beat tracking from a short excerpt is ambiguous by nature: a 140 BPM track with a half-time feel reads as 70. Check the estimate against the track and halve or double it if it is off.
Will the prompt recreate the reference track?
No, and nothing here claims it will. The prompt describes measurable qualities of the recording. A generator given that prompt will make something in that neighbourhood, not a copy.
Why are there two style lines?
The same descriptor set is rendered in English and Turkish from one bank, so the two lines say the same thing in the same fixed order. Use whichever language your generator handles better.
