Frequency Video Generator

Curve shape ?Pick the overall EQ curve: a symmetrical bell, a high-pass or low-pass rolloff, or a shelf that boosts/cuts everything past a point.

Direction · Gain ?Boost raises the curve, Cut lowers it. The slider sets how many dB the effect moves, from subtle (1 dB) to strong (18 dB).

+3 dB

Frequency type ?Single frequency targets one point on the spectrum. Band lets you set a min and max range instead.

Frequency ?The center frequency in Hz where the curve is applied. Drag the slider or type a value directly.

Arrow keys on the field: steps of one third-octave

Width ?How narrow or wide the bell is around the center frequency. Narrow is surgical (high Q), Wide is gentle and broad (low Q).

Band, min/max freq ?Sets the lower and upper edge of the frequency band in Hz. Min is always kept below max.

Min freq

Max freq

Range 20-20000 Hz: the min value is always kept below the max

Band shape ?Centered bell tapers smoothly to a peak in the middle of the band. Flat plateau stays level across the whole band with a clean top.

Mode ?Single shows one curve. A/B compare lets you build a before/after pair and step through both states.

Format · Export · Style ?Format sets the aspect ratio (16:9 or 9:16). Export sets the output type: MP4 dark has a solid background, MOV alpha and PNG alpha keep transparency, MP4 chroma uses a solid color key. Style switches between a technical look and a social-friendly look.

Timing ?Duration is the total length of the overlay. Hold-in keeps the start still before animating; hold-out keeps the end still before it disappears.

Duration s ?Total length of the overlay in seconds, including the hold-in and hold-out.

Hold-in ?Seconds the overlay stays frozen at the start before the curve animates in.

Hold-out ?Seconds the overlay stays frozen at the end, after the curve is fully drawn, before it disappears.

Video text · Curve color ?Optional text label shown in the video, plus the color of the curve line. Hz and dB toggles below control whether those values are printed on screen.

Hz in video dB in video (e.g. +6 dB)

File name ?Name used for the exported file. Leave on auto to generate it from the curve settings, or type your own.
