Frequency
Sound generated from the letter values (abjad) of the text; independent of recitation.
Bar height = weight (count); position = frequency (logarithmic)

The total is shown as a number only; it is not part of the sound. The sound comes entirely from the letters.
Measurement charts
Charts fill while sound is playing.
Envelope spectrum — measured, 0.24 Hz resolution
Wave spectrum — measured (1–1200 Hz, logarithmic)
Variation spectrum — periodicities of the letter sequence
Position = period length (letters, logarithmic); height = power. Label: letters/period and its Hz at the chosen k.
How it works
Derived from letter values only, independent of recitation. Below 100 Hz: envelope modulation · 100 Hz and above: carrier tone; in a verse with no letter above 100 Hz the letters themselves carry, octave-folded. Sound is generated live in the browser; no file.
Sequential: in recitation order, each verse's own frequency profile (its carriers and envelope) plays one after another; verse duration is proportional to its letter count and the playing verse is marked in the list.
Flow: the letter sequence as one phase-continuous wave; each letter lasts k full periods of its own frequency (intrinsic duration = Σ 1/value). In the folded mode the per-letter tempo is fixed.
At surah level too the sound comes from letters only; in Sequential mode each verse plays with its own letters, in order.
