بِسْمِ ٱللَّهِ ٱلرَّحْمَٰنِ ٱلرَّحِيمِ
Bismi Allâhi alrraḥmâni alrraḥeemi
إِذَا جَآءَ نَصْرُ ٱللَّهِ وَٱلْفَتْحُ
Iẕâ jâa naṣru Allâhi waalfatḥu
وَرَأَيْتَ ٱلنَّاسَ يَدْخُلُونَ فِى دِينِ ٱللَّهِ أَفْوَاجًا
Waraayta alnnâsa yadkhuloona fee deeni Allâhi afwâjân
فَسَبِّحْ بِحَمْدِ رَبِّكَ وَٱسْتَغْفِرْهُ إِنَّهُۥ كَانَ تَوَّابًۢا
Fasabbiḥ biḥamdi rabbika waistaghfirhu innahu kâna tawwâbân
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.
